Asphalt material is used in construction of pavements because it lasts for long and has the ability to support heavy loads. Nonetheless, this material needs proper maintenance to last for many years. Different factors affect the quality and life of asphalt including sunlight, snow, water, salts, and gasoline products. By consulting an asphalt company Maryland area, you can install new asphalt pavements or repair the damaged ones within your premises.
Despite the economic and aesthetic values of asphaltic material, they also suffer from structural defects. As the blacktop ages, it begins to disintegrate in strength. The binding properties of the petroleum-based binder diminish with time. A constant oxidation process takes place in asphalt pavement where the molecules are continuously shifting and re-assembling as they search for equilibrium status.
Apparently, this oxidation process takes place in the rest of the asphalt life. It is until the oxidation is over that they life of the pavement ends. This takes many years and lasts the lifetime of the paving material. However, the oxidation is accelerated by environmental factors meaning that the blacktop can disintegrate fast than expected.
Heavy loads cannot be supported when the subgrade is weak and soon other problems start occurring. The cracks enlarge and form potholes, and if the freeze-thaw cycle occurs, it leads to formation of many potholes. The asphaltic paving material is only as strong as the sub base in which it sits on.
The salts are applied as part of the snow clearance process during the heavy formation of ice in winter. However, those salts can react with asphaltic material and break it down leading to damages. Gasoline products such as engine oils and transmission fluids also react with asphalt material making the binding properties loose.
When you see the surface of pavement unraveling, it means that the aggregate mixture is wearing out. This is caused by deteriorating bonding structures of blacktop. When raveling continues, the asphaltic materials further weaken and the fine hairline cracks now spread wide as well as deepen. At this points, the cracks are clearly visible and you need a corrective measure to prevent further disintegration.
Most of the defects are corrected before they affect the sub base. Sealcoats are used to prevent ultraviolet rays and water from damaging the blacktop. A properly maintained blacktop can enhance the life of pavements because it shields and protects the sub base. Installation of sub base is costly and this section of the roads should always be protected by maintaining the blacktop in good condition.
If that water is allowed to remain stagnant on the surface, it can eventually enter the sub base and cause troubles. A firmly compacted base can promote the life span of pavements because it does not allow shifting of soils. A strong base helps the pavements support heavy loads preventing tearing apart of pavement surface or formation of depressions. By contacting an asphalt company Maryland area, you are able to install, repair, and maintain your driveways or parking lots in the right condition.
