Construction of pavements evolved and undergone many changes with regards to mix design methods and mix characterization over the years. The Marshall mix design method is currently used in Malaysia to construct hot mix asphalt (HMA) pavements. In this study, the Superpave mix design method was employed to design the HMA mix. Further investigations to evaluate the rutting performance of asphaltic mixtures using both mix design methods were conducted. Rutting is one of the most common pavement distresses in tropical climatic condition. This test was conducted on eight different types of HMA mixtures consisting of two different aggregate gradation of maximum nominal aggregate size of 12.5 and 9.5 mm. The binder used in the HMA mixture is of penetration grade 80-100 and 60-70. The Simple Performance Test (SPT) was used to evaluate rutting on both Superpave and Marshall mixes. Results showed that the Superpave mixtures are more rut resistant compared to Marshall mixtures. This is especially true for Superpave mixtures using binder penetration 60-70. The SPT provides a full characterization of the mix over a broad range of temperatures and loading frequencies, hence this test is highly recommended for evaluation of rutting performance in tropical climatic condition.
