A pothole is a type of failure in an asphalt pavement, caused by presence of water in the underlying soil structure and traffic passing over the affected area. Water in the underlying soil first weakens the supporting structure. Traffic then fatigues and breaks the poorly supported asphalt surface in the affected area. Continuous use ejects both asphalt and the underlying soil material to create a pothole. Conventionally the road maintenance is done by adding the road patching material into the potholes. There are various state of the art being used currently, however they do not solve the problem permanently.
The road patching material is developed using recycled asphalt from pavements. The invention even offers superior features. The material being used has been tested by certified laboratories and has conform to the standard and quality required. It is cost effective, environmentally friendly and reliable as a permanent solution to potholes.
The road patching material has been invented as a permanent solution to asphalt roads that are proned to develop potholes over time. It can be used as part of regular road maintanence works to improve the surfaces of heavily used highways. The material can be also stored as cold mix asphalt.
This invention affords the following advantages to customers:
