Researchon Construction Qualityindexes Of Warmasphaltmixtures

China is currently in the period of rapid development in superhighway construction and maintenance,the quality of hot asphalt mixture generated every year is nearly hundreds of millions of tons. As a country to sign Kyoto Protocol, China is confronted with a number of serious challenges. Saving energy is an important issue which is related to our country’s national economy and people’s livelihood. If the technology of warm mix asphalt mixture are popularized and applied in highway construction, it will not only decline engineering cost, economize resource, protect the environment, but also advances the quality of engineering, and make contribution to the promotion of the nation’s sustainable development,and then harvests profound economic and social benefit. Therefore, it is of great significance to carry out warm mix asphalt mixture research.Based on different classification and composition of warm mix asphalt mixture design and construction process, this paper carried out the warm mix asphalt mixture quality control experiments,which include the impacts that the temperature mixing agent dosage on asphalt three indicators and viscosity, and the corresponding warm mix asphalt mixture experiment, such as rutting test, water stability test and low temperature bending test, and then concluded the change rule of each index with the temperature mixing agent dosage. Finally, the paper combinedwith laboratory test data and actual construction engineering, and made suggestions about warm mix asphalt mixture construction quality control information.
