Claims8
A road paver, comprising:
- a head;
- a body comprising a front end and a tail end;
- a feeding device, disposed in the front end to convey polyurethane concrete, and the feeding device comprising a stirring device;
- a stone paving device, disposed on the tail end to spread crushed stone over a road, and the stone paving device comprising a stone feed bin carrying the crushed stone;
- and
- a concrete paving device, disposed between the feeding device and the stone paving device and connected to the stirring device, and used to spread the polyurethane concrete across the road;
- wherein:
- the feeding device further comprises:
