Method of construction of roadway - involves filling parallel trenches with hardenable mixture to form solid embedded strips of road

摘要

The roadway is constructed by digging a pair of parallel trenches and filling the trench with a mixture of material and an appropriate flexible hardener to form a solid embedded mass whose surface presents a strip of road. The material used to fill the trench is pref. that which was excavated to form the trench. This is compacted into the trench, and may incorporate a drainage channel and reinforcement rods which are driven into the bottom of the trench.
