Variability of Cement-Treated Layers in MDOT Road Projects

The Mississippi Department of Transportation (MDOT) revised the specifications for cement-treated bases between the 1990 and 2004 editions of “Mississippi Standard Specifications for Road and Bridge Construction.” The required compressive strength of laboratory specimens was reduced in an effort to reduce shrinkage cracking in the cement-treated layer. The compaction effort of the in-place cement-treated base was increased to produce a stronger layer. These significant changes impact in-place properties and performance of the cement-treated base. Prior to this research, the author is not aware of any field studies that have been conducted to determine how these changes affected in-place properties. This research documents field and laboratory testing of two MDOT road projects. Findings were compared to project specifications and cement-treated base property variability was calculated and graphically illustrated.
