The increasing number of vehicles in Yogyakarta has led to long lines of heavy traffic, especially at the road intersection, which may damage the flexible pavement layer. The excessive load of moving vehicles has reduced the ability of flexible pavement to withstand the braking force of a moving vehicle, which inevitably leads to shoving and slip cracks. Therefore, rigid pavements are more applicable in such case. This research was conducted to obtain the characteristics of rigid pavement using chemical admixture with variations of 0.6% Plastocrete RT06 and 3% Sikament-NN, affected by temperature changes on compressive strength, and having a decrease in value due to the load as indicated by the Abaqus software. The research was conducted with cylindrical specimens method with different curing of a soaking and elevated temperature of 40oC for 12 hours with planned concrete quality (f’c ) >37,35 MPa (>K-450). The value of concrete compressive strength is of 13.18% with optimal compressive strength values occurring in concrete without special treatment. The decreasing value of the pavement is modeled with compressive strength of 48.27 MPa (K-580) in immersion concrete and 41.91 MPa (K-500) in concrete with elevated temperature, with the load obtained from LHR of 2017 using Abaqus software, each of which is 0.2235 mm for immersion concrete and 0.237242 mm for concrete with elevated temperature.
