Road Construction: History and Current Methods Bright Hub
Road Construction: History and Current Methods. In ancient times, river transport was much faster and easier than road transport. The Romans were one of the first to build stone paved roads in North Africa and Europe to support their military operations. Later the Arabs built roads that were covered with tar.Excavation is critical in any construction project that involves removing dirt, rocks, and any unwanted materials from a site in order to build a strong foundation for a structure. When it comes to road construction, good excavation work is the first step to a strong and stable subgrade, thus demanding execution with precision using the rightExcavation in Road Construction: Methods and Steps
