Let's take a look at several of the traditional types of road construction techniques and materials in use: Asphalt – One of the most popular types of road construction ever since its inception in the early 1920s is asphalt paving. In this construction technique, a layer of asphalt is laid on top of an equally thick gravel base.
compaction requirements for various soil types are given in Table 2-1. When fill materials have been thoroughly investigated and there is ample local experience in compacting them, it is preferable to specify details of compaction procedures, such as placement water content, lift thickness, type of equipment, and number of passes.
Lightweight Fill Materials for Road Construction Guy Kohlnhofer, Braun Intertec Corporation A lightweight fill is any material used to replace a heavier in situ soil to reduce the load on subgrade soils. The use of lightweight fills is increasing in many areas of the United States. Various materials have been used; however, because
