Road construction needs lots of machines. The earthmoving machinery prepares the ground, then other machines continue by adding the first coat, the bond coat and the wearing coat.
The lime spreader spreads the lime used as a binder for the road’s stabilization. The chip spreader spreads the gravel that make up the first coat; it is used to improve the ground capacity by making it uniform. The bond coat, under the wearing coat, is made by a sprayer; it is made of hot binder or bitumen emulsions. When the sprayer is equipped with a gravel hopper, it is called a combined sprayer. The top layer of the road, or wearing coat, is made of bitumen. The surfacing is produced by a coating plant. A finisher is used to spread the bitumen on the road.
For repair work and asphalt pavement recycling, a pavement milling is used to scratch the asphalt and a soil stabilizer to mix the binder and stabilize the road.
Finally, the arm mower and the mulcher help keep clean the sides of the road.
