Description: Technical Report
Abstract: There is a definite need to make use of locally available materials in construction to minimize time and cost of construction. This report described a technique for constructing bridge approaches, abutments, and piers using locally available soils and military stock membrane (T-16 and T-17). The construction of the bridge described in this report involves confining sand with T-16 and T-17 membrane to form the various structure units. After the approach, abutment, and piers were constructed, treated timber was used in construction of the stringers, decking, and tread. The bridge was constructed with a small labor force and a minumum amount of equipment. The construction was simple and fast, thus making it readily adaptable to conditions faced in the theater of operations. The bridge was built in 1977, and the performance was recorded for a period of approximately five years. During this time only minor scour problems developed around the piers and these problems were handled with a minimum of maintenance.
