How Sealcoating Prevents Damages on Asphaltic Pavements

Sealcoats provide a protective barrier on asphaltic pavements, which allows the asphalt material to oxidize slowly. The sealcoating prevents ultraviolet rays from directly reaching and heating the blacktop. When ultraviolet rays directly heat the asphalt material, they accelerate the natural or normal oxidizing process meaning that the pavements dry up and harden too fast than expected. This results to premature damages of roads and parking lots since fine hairline cracks start forming. 

"Sealcoating preserves the blacktop"

A sealcoat provides a membrane cover, which bars the ultraviolet rays from directly baking the asphalt material. When cracks are formed due to effects caused by ultraviolet rays, they allow water to penetrate and settle at the subgrade layer of roads and parking lots. Water causes more harm to the aggregate base, which is the building block for your roads. The base of roads supports the pavement layer and the loads that turns over the roads.

Water loosens the aggregate material and thus makes it start crumbling down. In addition, when water remains in the cracks, during the winter condition, it may freeze. As it freezes, the water expands and it enlarges the cracks in areas where is has collected. After the cold season, that frozen water melts down through the process of thawing and the enlarged cracks are left as empty spaces or voids.

What happens is that the material, which is on top of the void, that is, the asphalt pavement material, collapses and fills the empty space. This leads to formation of potholes in roads and parking lots. One thing with potholes and extensive deep cracks is that they are costly to repair. When sealcoats are applied in the right time, they prevent the speedy drying or oxidation of asphalt material. Sealcoats help improve the elasticity of asphalt pavements ensuring that they easily expand when heated and contract when cooled. This way, cracking is minimized.

Chemical substances like gasoline, de-icing salts, oil spillage, and transmission fluids also accelerate the oxidizing process in asphalt material. When a sealcoat is applied, it helps prevent these chemicals from coming into direct contact with the asphaltic pavement thus preventing premature damages.

In short, the oxidation process of asphalt is a complex molecular behavior, which can help understand how asphalt pavements are affected or damaged by factors like sunlight, water, snow, de-icing salts, oils, gasoline, and transmission fluids. A pavement, which is treated with use of sealcoats, can last for long thus helping prevent unnecessary expenses associated with premature damages on asphalt pavements.

When is sealcoating done?
Sealcoating is done regularly as part of the maintenance process of asphalt pavements. When a new pavement is constructed, it should be allowed to cure or dry the surface oils before a sealcoat is applied. This may take a couple of months depending on the viscosity of the asphalt and how fast it dries up. If the sealcoat is applied before the asphaltic blacktop cures properly, the coating may not fasten or bond well with the asphalt material.

After the first coating is done, other coats are applied in a period of about 2 to 5 years. This is a continuous process, which should be undertaken periodically until the end of the life of the pavements. When you notice that the color of your asphaltic pavements has changed from dark black to gray, you need to ensure that you sealcoat your drives, parking lots, and road surfaces to prevent further damages from occurring due to accelerated oxidation.

How Environmental and Man-Made Factors Cause Damages On Asphalt Pavements

Asphalt undergoes chemical changes at the molecular level and the intermolecular level also known as microstructure. Because of the complex nature of molecular interactions in asphalt, the oxidation of this material is complicated by the different molecules interrelation. There is a mixture of polar and non-polar molecules in asphalt. Polar molecules have a positive charge on one side and a negative charge on the other side while non-polar molecules have their electrons distributed in a way that there is no abundance of charges on both sides. 

"Cracks developing on asphalt surface"

In essence, there are predominantly thousands of chemicals with open chain structure in asphalt, which makes the material to have a considerable level of un-saturation in its molecular structure. It is this open chain molecular structure of asphalt, which allows it to easily interact with weather elements, chemicals, and salts. Molecules from other substances can attack and disintegrate the asphaltic material molecules leading to changes in its structural composition.

In the microstructure of asphalt, there are three-dimensional relations of polar molecules, which are referred to as asphaltenes, and these are dispersed in a fluid made up of non-polar or low-polarity molecules, which are known as maltenes. The intermolecular bonds are weaker than the bonds of the fundamental hydrocarbons in asphalt material. This means that these intermolecular bonds break up first and determine the behavioral patterns of asphalt material.

The intramolecular and intermolecular relationships in asphalt material make it behave in two major ways. First, it is elastic due to the effects caused by polar molecules interrelation. Second, it is viscous since the different parts of the polar molecules are able to move relative to one another when dispersed in the fluid non-polar molecules.

When oxidation occurs in asphalt pavement, it makes the material become dry and brittle. Exposure of asphalt to oxygen triggers a molecular process, which leads to creation of new polar bonding sites or zones. What happens is that the increased polar sites or zones in asphalt materials make the molecules to rearrange and shuffle about as they search for bonds that can create equilibrium or bring a thermodynamic stable state.

This is a self-assemblage process, which continues for the rest of the life of the asphaltic pavement material. With time, as the polar sites discover molecules to attach on, the asphalt molecules bond firmly together with the aggregate material. The result is a pavement, which is stiffer, harder, and brittle. As asphalt oxidizes and dries up, it loses its elasticity and starts to fail.

One sign that signifies the failure of asphalt due to oxidation is the change in color. Initially, asphalt has a jet-black color but over time, due to oxidation process, it turns to light black and ultimately changes to gray. The drying asphaltic material begins to crack as it loses its bonding properties. Before the oxidation process reaches an equilibrium point, it may take about 5 to 15 years depending on how the material is affected by other factors like sunlight, chemicals, and water. This substantiates the reason why the estimated lifespan of asphalt pavements is about 20 to 25 years.

When oxidation process stiffens the paving materials, its ability to support heavy loads is reduced. This causes asphalt fatigue leading to formation of cracks and premature failure of asphalt. Heat from the sun causes the asphalt material to cure and dry fast than intended. Moisture from rainfall can accelerate the damage on oxidizing asphalt since it contains a large amount of polar-constituent molecules, which in turn attract the water molecules. Sealcoating can help delay or slow the rate at which asphalt naturally oxidizes.

How Sealcoating Delays Asphalt Oxidation Process and Prevents Premature Pavement Damage

Sealcoating is an integral part of asphalt maintenance. Asphalt is a commonly used paving material in driveways, parking lots, and roads. It is preferred in constructing road surfaces because it is relatively cheaper to install compared to other materials like concrete blocks. However, when asphalt is laid down, it undergoes chemical changes throughout its lifespan, which can affect its visco-elasticity properties and durability.

Asphalt pavements have a life expectancy of about 20 to 25 years but this lifespan can be reduced by effects caused by environmental factors like ultraviolet rays, snow, and water. Asphalt paving material used in road construction undergoes an aging process known as oxidative aging. From the time the asphalt is laid down, it starts undergoing oxidation. When examining how environmental and manmade factors affect the quality of asphalt pavements, it is important to consider the asphaltic molecular structure and its changes.

Manmade factors like oil spillage and de-icing salts can also degrade the quality of asphalt pavements. The vulnerability of asphaltic paving material to weather conditions and chemical substances can be reduced by applying a top membrane cover known as sealcoat through the process of asphalt pavement sealcoating.

Asphalt pavement material is made up of aggregate, fillers, and binders such as bitumen, which help in holding together the mixture. Since asphalt pavements will naturally degrade with time, understanding the elements, which speed up the degradation process, can help in putting up preventive measure thus prolonging the life of roads, driveways, and parking lots.

What is sealcoating?
Sealcoating is the application of a weatherproof membrane layer on top of the blacktop of a road surface. A sealcoat is a surface treatment aimed at preventing damages on blacktop caused by things like heat from the sun, moisture, and oil spillage. The sealcoats are made of asphaltic material like emulsions, cutbacks, and paving grade-asphaltic cement and are modified with asphalt liquid mixtures such as latex and polymers.

One thing with asphalt sealcoats is that they only provide a protective barrier and do not cure problems that may exist underneath the pavement such as large cracks and road foundation failure. This means that before a surface treatment is done with use of sealcoats, if there are any damages on pavements and sub-base layer, they should be repaired. Otherwise, the sealcoat may only mask the problems and soon cracks and other deformities on pavements begin to show up again.

Remember to take a first aid class before your next camping experience. 

Planning ahead of the camping trip helps in having all the necessities in the camping list identified and sort. An enlightening and fabulous camp experience is one that is free from inconveniences caused by missing camping supplies. With your finances, a camper can budget for all the requirements. One should jot down essential items, which include a tent, food items, right cloths for the prevailing weather conditions and of course the travel documents. 

A first aid kit and personal cleanliness items are also important for your Safari. The tent should be of the required size depending on the number of pax included in the camping trip. There are different types of camping tents and the number of people and your pocket determines the one to buy or hire. It is recommended that a camping trip experience needs to be as simple as possible. Even if your finances allow, one should try to buy a simple tent.

During your camping experience, you certainly want to enjoy those camping recipes, which you have missed in your daily menus. Source for simple but rare camping food ideas and pre-cook the camping food especially the meat. You can buy pre-cooked food items from the food stores and keep it refrigerated till the moment of camping safari. Ask your family members and especially the children to help you identify the camping food items they need to be included in the menu.

The menu should be easy to prepare. Simple camping recipes such as sea food burger can be sourced. The sea food can be pre-cooked and packed. Consider deep frying or pan frying as this helps it last longer. It is recommended that food that doesn’t require refrigeration is more appropriate. Bread rolls, buns, nuts, and fruits. However, you definitely need some cooling items for the perishable items such as vegetables and pre-cooked food. Coolers and ice blocks can be sourced.  

The weather should determine the kind of camping cloths to wear. You need to inquire from the meteorological department or tour agents on the weather conditions to expect on the camp site. In extreme cold weather, you need to have the heavy woolen cloths. Bright sunny days require light cloths. 

You should remember that bright day can be preceded by cold nights. You need to be prepared for such weather variations. Rainy weather implies that rain coats should be packed in your bags. You may need to hang up your wet and damp cloths on a clothes line. Cloths pegs are also essential.

Your camping first aid kit is significantly important. You may fall on those rocky grounds or be pierced by the thorny shrubs. Other items you need to have are gazebos, sleeping bags, picnic rags, simple barbeque cooker, lighter, camping lantern and chair and needless to mention umbrellas. Your personal cleanliness’ items such as tooth brush, tooth paste, bathing soap, towel, and anti-sun radiations lotions should also included in the camping checklist.

Don’t even think you have exhausted the camping checklist just by the first jotting. You will surely be surprised how many essential items you may have omitted when you go through the list with your family or friends. Consult them over and over again until the moment of camping. 

Don’t forget to refer to friends who have had such an adventure. They will more likely mention to you the areas they failed during their camping and what they did not include in their camping checklist such as the camping gear. This way you are able to improve on your camping preparation. Experts may as well help you out to plan for your camping more comfortably. If you have difficulties, consult them.

Dubious High Yield Investment Companies Stealing Billions of Dollars

Dubious high yield investment companies stealing billions of dollars from consumers every year in what appears to be a cold-blooded theft. Even the internet giants who should be shielding consumers from these malpractices are continuing to promote the sites. Search engines and electronic money transfer sites are some of the organizations who could help curb the menace but apparently, these sites continue supporting the perpetrators.

Internet seems to be the most vulnerable environment for consumers with billions of dollars being stolen from consumers. I am not talking of the high-end classic theft such as phishing and cyber crimes but about dubious websites that are operating freely and undeterred. They are using business models that never work, and they promise internet users of getting rich fast.

This never happens anyway, but why are the sites being allowed to continue operating yet they can be stopped. With so many complaints online, nothing seems to be happening yet consumers from all over the world are losing money?

Who owns 2 dollar clicks site yet this site is supported by one of main electronic money transfers. And, what about Ad Click Xpress, which has changed its name multiple times yet it is soliciting for people to continue pumping their dollars into their program. Surely, who owns the internet and who controls it?

Remember that ;

Wonga Releases 12 Portraits Film...What Does A Movie Has To Do With A Payday Lender?

Wonga released a 28- minute film, which apparently did not feature its name, nor the puppets that are associated with its site and ads. Wonga seems to be sympathizing with its exploits that are in pain accusing the payday lender of reaping money from consumers who are regarded as financially unstable. The release of the movie comes at a time when Wonga is under pressure from the MPs accused it of imposing extra-hefty interest rates that are as high as 5,853%. 

Whereas the movie may give the impression that consumers are happy with the payday lender, this might not be the case. If those who feel they have been exploited by this lender could be featured in a similar movie, it would be tears of agony and bitterness. But, who is to blame for the pain caused by payday lender to consumers?

Gary Tarn, the BAFTA-nominated filmmaker was granted a free rein to produce a film for Wonga without an editorial control by the lender. This would create the impression that the lender was not biased in the content of the film. The series featuring 12 portraits of Wonga customers talking of their passions has been cited as an expression for many who feel that these loans have helped them greatly but their voices have never been heard.

All we hear is the tainted image and accusations of preying consumers of their hard-earned money by payday lenders but few seem to be excited about these lenders. The anguish and pain consumer are experiencing overwhelms the joy expressed in the 12 Portraits film footage. Whether it is a consolation gimmick or voice for the majority who have benefited and are happy about this lender, the feelings about payday lending are far from happiness.

Wonga is the most profitable payday lender in Britain, but its profitability may be resting on bitter feels. After all, much of the revenue generated by these cash advance service providers is derived from the fees and charges levied on consumers who rollover balances or take multiple loans. Payday loans are not intended for long-term financial solutions in the first place.

Any payday company capitalizing on penalizing its consumers for failure to repay their first loan as agreed on the term has a hidden agenda. Payday loans should only be borrowed once and should be repaid after the given period of lending. However, lenders lure consumers to become repeat customers or rollover their balances, and this is where the problem starts.

These lenders should discourage rolling over of balances or obtaining multiple loans within a given period because after all, the blame for preying consumers erodes their reputation and image. It might have been easy for Wonga to find 12 people who could speak, something passionately about the company, but what about the thousands of consumers struggling with heftily priced loans? Who would help them air out their voices? 

The subject of payday lending is very sensitive, and although the lenders say, the loans are for emergencies, consumers need to be informed on what is important and what is urgent. Every other financial need might be important but not an emergency. Many consumers who borrow Wonga payday loans have misplaced priorities and misunderstanding of what the implication is. A payday loan should never be rolled over and multiple borrowing should never be entertained. These loans are too costly to bear whenever there are rollovers and multiple borrowing.

Nevertheless, it cannot be assumed that these loans do not benefit consumers. A few people can attest to the fact that payday loans have helped them in a way they could never have been assisted . This should be praised and acknowledged but majority of borrowers are never happy with structure of the lending system and they feel reaped off their money. The 12 Portraits may just be another corporate video that is deemed to conceive the truth from the eyes.

Unfortunately, even if people can see the joy in the hearts of those who passionately praise the work of Wonga, the film might not erase the ill feelings of thousands of consumers who in one way or another feel they have been exploited. Consumers should borrow wisely and understand that payday loans pose a real danger to their finances. Installment loans are the new form of payday loans, which seem to be growing fast but although they attract less interest rates, they are also highly priced. Wonga loans can only help you when you are in critical need of cash but not just another emergence.
