Road Pavement Treatment Types

A bonded wearing course is relatively fast process, done using a single machine If used correctly, it can extend pavement life 10+ years, and cost less than conventional AC overlay Fog Seal A fog seal is a light application of a diluted slow-setting asphalt emulsion to the surface of an aged pavement surface...

Road Pavement

The Road Pavement is the portion of the road located directly above the subgrade, and beneath any wearing surfaceIn urban areas it is often bordered by kerb & channel, and in rural areas by road shouldersIt is typically constructed from compacted imported material such as crushed rock The road pavement is sometimes broken up into two components, namely the base and the sub-base...
