Developing Best Practices for On Site Production and Placement of Cement Stabilized Crushed Stone Base Course Material

A crushed stone cement stabilized base course (CSCSBC) material consists of cement, water, crushed stone and any additional admixtures compacted to a high density to form a hardened structural material with specific engineering properties. Currently there are many variables that can affect the quality of the material in the field including: when and how to add water, spreading, placing, grading, and compaction techniques used on the cementitious material. Arkansas State Highway and Transportation Department (AHTD) has seen core samples crumble upon acquisition, which indicates a problem with the material. Current specifications dealing with CSCSBC material production and placement are vague. Due to all of the variability, in field best practices are needed to ensure that a uniform high quality material will be obtained on each job site.
