| Abstract | ||
| The main objective of this study is to investigate the effect of adding hydrated lime on the moisture damage resistance of asphalt concrete mixtures. In this study two samples of asphalt concrete mixture were prepared, the first sample represent control mixture, and the second sample contain hydrated lime with rate (0.5, 1, 1.5, 2.0, 2.5%) by the total weight of aggregate. The properties of control mixture and Lime-asphalt concrete mixture were evaluated by Marshall tests results, Indirect Tensile Strength (ITS) results, and retained Marshall Stability (RMS) test results. The results for these tests indicated improvement in mixture proprieties, increased resistance of asphalt concrete against moisture damage, and reduced effect of water on the properties of asphalt concrete. As a final result, the use of (2%) hydrated lime enhanced asphalt concrete properties and produce durable mixtures for highway construction. | ||
