ABSTRACT

The increase in traffic growth on the Taweli - Pantoloan section, also increased the traffic load that passes through the section and caused rutting and cracking. The modulus elasticity is an important factor that affects the performance of asphalt pavement, therefore it is necessary to predict when narrow cracking, wide cracking, 50% cracking, and rutting will occur. HDM III is used to predict when it will occur, from CBR subgrade and annual average daily traffic data on Tawaeli – Pantoloan section, the pavement performance is planned for 5,10, 15, and 20 years. From the results of the study, it was found that the increasing road performance, the greater the value of the traffic load, which in increasing the thickness of asphalt pavement, and the faster the road will experience narrow cracking, wide cracking, and 50% cracking. Variation of modulus elasticity gives that the lower the modulus elasticity of asphalt mixture (SME), the faster the cracks occur on the asphalt pavement and vice versa. The effect of narrow cracking (TYN), wide cracking (TYW), and 50% cracking on the depth of rutting (RDM) are directly proportional.
