Road Construction Process Overview by AU— TECHNIQUES is a document available to read on EtoBox.
Road construction requires creating a continuous right-of-way by removing obstacles, keeping grades low for vehicle and foot travel. The process begins by removing earth and rock, constructing embankments, bridges and tunnels, and removing vegetation. Drainage systems are installed to prevent erosion and sedimentation. The road bed is prepared by compacting fill and subgrades are proofrolled before paving or adding a gravel surface. Maintenance is needed over time to repair damage from vehicles and weather.
