摘要
This research applies natural rubber latex (NRL) to improve the quality of cement clay roads. In laboratory test, multiple specimens have been prepared. The research uses high ammonia latex concentrate (60% Dry Rubber Content (DRC)), mixed with surfactant and pure water. Then it was sprayed and mixed to the red dirt road that has been admixed with cement. The red dirt material used for the research was taken from Ubon Ratchathani province, northeastern of Thailand. The dirt soil is a mix of gravel, sand, and clay with poorly graded grain size distribution. The test uses varying amount of cement (4%, 6% and 8%), and NRL (0%, 5%, 8%, 10%). From the experiment, the best mixture ratio is to use NRL 5%, cement 8%, and surfactant 2%. With seven-day air-curing, the averaged compressive strength of the rubber latex soil cement specimens was 1.72 MPa. (C) 2018 INT TRANS J ENG MANAG SCI TECH.
