Repeated wheel load and temperature thermal stress will cause stress and strain and then deteriorate pavement's performance. It is important to identify damage to stop it only at the surface layer and not to spread to the lower layer by measuring tensile stress and strain under stress applied. The research aim is to know Hot Mix Asphaltic Concrete behavior on surface pavement, which includes tensile stress and strain, and its resilient modulus under load and temperature changes with laboratory test using UMATTA. Load varies from 187,5 to 2000 N, while temperature varies between 25, 37,5 and 50 0C under 1 and 0,3 Hz frequency. The results indicated that temperature is the most responsible for pavement surface damage compared to load and load frequency.
