TRB’s National Cooperative Highway Research Program (NCHRP) Report 597: Development of a Recommended Practice for Use of Controlled Low-Strength Material in Highway Construction explores 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. The report also examines a recommended practice for the use of CLSM that was developed through a series of full-scale field experiments.
This report presents the full text of the contractor’s final report of the project and three of the five appendices, which present the test methods (Appendix B), specifications (Appendix C), and practice (Appendix D) recommended for implementation. The corrosion study (Appendix A) and implementation plan (Appendix E) are available online as NCHRP Web-Only Document 116.
There is a summary document, Paths to Practice, available.
