Résumé
Controlled low strength materials (CLSM) are increasingly used in urban areas to fill the trenches that constitute the technical urban underground network. CLSM replaces compacted rock stone; it is delivered with a concrete mixer and self-compacts due to its high water content. Few quality control requirements are listed in its specifications, none of which mention draining capacity and ground rigidity. Using data from four urban test sites, our study shows that the consolidation of CLSM varies with ground type, which has major implications for quality control specifications. The primary tool used to measure CLSM consolidation was the dynamic cone penetrometer, while the current standard is based on ball drop to determine suitability for load application. The dynamic cone penetrometer had more information on ground conditions than the drop ball tests. The results will be incorporated in a consolidation model to estimate the minimum time required before opening the road to car circulation.
