PS400 type Hydraulic Multiple-Hammer Concrete Road Breakers are the kind of special machines intended for rubblization technology of concrete pavement. After breaking the old concrete pavement, the sizes of fragments from top layer to bottom layer increase gradually. Through rolling, the top layer of fragments forms a flat surface and the lower layers of fragments forms an embedding and crowding structure. The road base can be effectively strengthened after paving new surface layer. The machine has been widely used in the reconstruction of old concrete roads in China and abroad. Users call it “King of Breaking”.
