Abstract
The present study evaluated the mechanical properties of open graded asphalt for semi-rigid pavements in order to determine the mixing proportion experimentally. A total twelve types of basic mixing proportions were set up and mechanical tests such as marshall stability, porosity, permeability, and cantabro loss were conducted based on Korean standards. From the tests results, it was found that the marshall stability in case of straight and modified asphalt increase up to the contents with 5.0% and 5.5% respectively. The porosity and permeability of asphalt tended to decrease as the asphalt contents increase, the coefficient of correlation between both were estimated 86%. The increase contents with asphalt range from 3.5% to 6.0% tended to decrease the cantabro loss and the modified asphalt enhanced the resistance of cantabro loss with range from 18.8% to 33.1% than straight asphalt under same asphalt contents. In comparison with test results and quality standards, it was concluded that the modified asphalt content of 4.5% is effective to adopt for open graded asphalt.
