Abstract:The purpose of this research is to evaluate the effectiveness of soil cement shrinkage crack mitigation techniques. Ten test sections, 1000 feet long, were constructed on LA 89 in Vermilion Parish. The shrinkage crack mitigation methods being evaluated include cement content, synthetic fiber reinforcement, interlayer, curing membrane, and curing periods.
After the test sections were constructed, their structural properties were assessed with the Dynaflect and Falling Weight Deflectometer (FWD). Crack mapping was conducted visually by field technicians and with ARAN by the pavement management section. The crack mapping of the field test sections will continue for a period of 5 years and a final report will be issued at that time.
