• Abstract:
  The Mississippi Department of Transportation 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 cementtreated ; base was increase 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.
