Development of a Recommended Practice for Use of Controlled Low-Strength Material in Highway Construction

This report summarizes the results of a project to evaluate the use of controlled low-strength material (CLSM) in highway construction applications, in particular, as backfill, utility bedding, and void fill and in bridge approaches. A key product presented in this report is a recommended practice for the use of CLSM that was validated through a series of full-scale field experiments. The report will be of particular interest to materials and construction engineers in state highway agencies and industry.
