Description

Construction method for rapid road construction

technical field

The invention relates to the technical field of road construction, in particular to a construction method for rapid road construction.

Background technique

Most of the current low-grade roads are cement concrete pavement or asphalt concrete pavement, and the road construction cost is high and the construction period is long. Other gravel roads or mud-bound gravel roads have poor driving comfort, large dust, and low traffic efficiency in rainy days. In addition, when the road needs to be demolished, a large amount of construction waste will be produced, causing environmental pollution. Especially for some temporary roads, the commonly used methods are precast concrete slabs or laying steel plates.
