Analysis of Defects and Damages of Materials in the Pavement Structures of Highways of Industrial Enterprises and Methods for their Elimination

The problems of the formation and spread of defects and damages on the surface of the pavement of roads of industrial enterprises with rigid pavement are touched upon. The results of experimental studies have shown that the upper layers of the pavement (pavement layers) often have signs of under-compaction and increased water saturation, which indicates non-compliance with the rules during the laying of the pavement, as well as decompaction of the mixture during the operation of the road, caused by high loads. The calculated indicators of the residual resource of the surveyed road indicate a significant decrease in the durability of pavement structures. The proposed solution to the problem consists in removing the top layer of the asphalt concrete pavement, repairing cracks, cavities and other damage to the bottom layer, and laying a layer of geosynthetic material, followed by rolling under asphalt concrete. This method has repeatedly proven its effectiveness and the ability to significantly extend the durability of the pavement structure as a whole.
