The tests conducted prove that the lack of interlayer connection of the asphalt layers or improper its performance cause that the construction layers work independently weakening as a result the construction of the road.

Proper connection of construction asphalt layers of the Surface increased significantly the durability of the whole road structure which allows for holding larger loading. Well combined layers work together as one monolith structure.

In addition, the performance of condensations of the sub-bases and asphalt layers aims at:

  • additionalstabilizing the sub-bases from aggregates;
  • preparingbase for the layers from mineral-asphalt mixtures;
  • sealingparticular layers;
  • performingfixed connection of construction layers.
