Effect of Curing Methods on Thermal Distribution and Mechanical Properties of Cement Treated Bases

This paper presents and analyzes the results of different curing methods of the different cement treated bases (CTB). Using 3 different curing methods is emulsion cure, wet burlap and wet geotextile. Results from the temperature monitoring data during the curing process at different depths in the CTB show that at the same depth, the curing by emulsion makes the temperature in the CTB higher than the wet burlap method from 120C to 180C and higher than the wet geotextile method from 100C to 130C. Curing method by emulsion makes the temperature of CTB highest, amplitude of temperature fluctuation in the pavement between day and night is up to 230C. For the other 2 methods, the amplitude of thermal fluctuation is lower, the wet burlap method is only about 50C and the wet geotextile method is about 100C. The results of drilled samples determined compressive strength and split compression at 14 days of the cement treated bases by wet burlap the best results
