Small percentages of hydrated lime were added to substandard clayey gravel to produce quality flexible base material which has received wide acceptance in Southeast Texas. The hydrated lime reacts with the clay particles in the gravel, producing a less plastic, more friable aggregate. After the gravel is placed and compacted, a cementing reaction develops between the calcium and the lime and the alumina and silica in the clay, hardening the gravel into a strong, stable layer that is relatively insensitive to water. Both CBR and Texas Triaxial tests indicate an improvement in strength. Also unconfined compressive strengths are substantially increased.
