Asphalt Pavement Jan 21, 2017

Aggregates for bituminous binder pave the way for increased resistance and damage capacity of natural factors on pavement, so less dust and waterproof, durable pavement roughness. Therefore, the road of asphalt pavement pavement was the most widely used in the construction.

Asphalt layer in asphalt pavement itself, belongs to the category of flexible pavement, but its base in addition to flexible materials, cement concrete or rigid or semi rigid hydraulic material.
