Technical Field

The utility model relates to the technical field of road pavement structures, in particular to a black pavement structure reconstructed from a white and black pavement.

Background

The cement concrete pavement (cement concrete pavement) is a pavement which takes cement concrete as a main material and is a pavement layer, and is called a concrete pavement for short. Also known as rigid pavement, commonly known as white pavement, which is a high-grade pavement. The cement concrete pavement is composed of various pavements such as plain concrete, reinforced concrete, continuous reinforced concrete, prestressed concrete and the like.

As far as China builds China, a large number of cement concrete roads are built in China, most of the cement concrete roads are repaired by adopting a method of adding white and black after being damaged, the problem of reflection cracks is easy to occur after operation, damage of different degrees is caused, the structural stability is poor, and the service life is seriously influenced.
