Abstract

The properties of coarse and fine aggregates used in hot-mix asphalt (HMA) mixtures significantly affect the performance of the highway pavements in which they are used. The selection of aggregate gradation for use in HMA pavement is important to pavement performance. This study was conducted to evaluate the effectiveness of aggregate gradation on HMA according to JKR specification/1988 and JKR specification/rev. 2005. The laboratory tests carried out to determine the properties of aggregates included sieve analysis, the Los Angeles Abrasion Test, Aggregate Impact Value and Aggregate Crushing Value. A Resilient Modulus Test and Static Creep Test were also carried out to determine the performance of HMA by using Materials Testing Apparatus. In general, the aggregate gradation of Mixture 2, which follows JKR specification/rev. 2005, is better than the aggregate gradation of Mixture 1, which follows JKR specification/1988.
