PROPOSED SPECIFICATIONS FOR SOIL-CEMENT BASE CONSTRUCTION IN THAILAND

According to NAASRA (National Association of Australian State Road Authorities) specifications, the minimum unconfined compressive strength of the modified Proctor compacted sample after seven days curing at constant water content should be 150 per square inch. The Australian experience showed that soil-cement with a high compressive strength developed undesirable crack patterns. The stipulation of a maximum value may assist in limiting this effect, and an upper limit of 250 lb per square inch at 7 days has been used. This implies that NAASRA recommended an unconfined compressive strength for a soil-cement base in the region of 150-250 lb per square inch after seven days curing. It is reasonable to suggest that the design criterion for a soil-cement mix should be 250 lb per square inch, the same as previously adopted in order that the exact quantity of cement required could be evaluated. But for field construction control, it is better to specify a value in the range of 200-300 lb per square inch, giving an average of 250 lb per square inch. (TRRL)
