What’s wearing down your old asphalt pavement?

wearing down your old asphalt pavement

We all want smooth, functional, and flawless pavements outside our homes that survive for decades. But this is a difficult thing to wish for. When maintained properly, pavements built by even the best of asphalt pavement companies wear down slowly eventually. After a decade of constructing the pavements, they start cracking and disintegrating. What leads to the breakdown and deterioration of your asphalt pavements? A number of factors are responsible for this. Given below are a few of them.

Sunlight

Asphalt is a combination of sand, rock and aggregates all held together by a glue-like binder known as asphalt cement. This binder starts breaking down due to constant and prolonged sun exposure. Once this binder fully dries up, there’s practically nothing that holds asphalt aggregates together, which results in asphalt disintegration and chipping.

Water

Asphalt surfaces are generally porous, and they allow easy water penetration through them. Water can seep in and wash out the base underneath it, causing it to crack, break down and collapse. If your asphalt pavement already has holes and cracks, it will be even more vulnerable to water damages. Not only this, the spots that experience continuous contact with water and have pools of water accumulated generally have softer pavement layer in those areas. These spots are prone to damage quickly.

Heavy Loads

Continuous heavy loads of vehicles cause asphalt to break down quicker. If your pavement is already exposed to other natural factors such as water and sunlight, constant traffic can fasten the process of breakdown and result in cracks or settlements.

Chemical Impact

If you park your vehicles and other appliances directly on the pavement, you might face the issue of pavement wear down often. Petroleum chemicals, oils, and chemical-laden gases used in these vehicles and appliances soften the asphalt pavement and cause it to break down rapidly.

Paving Errors

Sometimes, paving errors can lead to bigger pavement failures. Although the deterioration of asphalt pavement will happen eventually, errors in construction can speed up this process. Some of the common pavement errors include over or under compaction of the asphalt, improperly compacted base, improper asphalt temperature, poor drainage, etc.

Proper maintenance is key to protecting asphalt pavements from the external factors that wear it out. But the deterioration is inevitable. The best solution for this problem is to repair the asphalt pavement at the earliest to avoid any inconvenience.
