An unanticipated sideeffect of China’s developing economy was the increase in heavy road trafficvehicles utilizing high pressure tires on both new and old infrastructure.Today the extent of rutting has become one of the main forms of asphalt road surfacebreakage. To improve the robustness and high temperature properties of roadsurfacing asphalt, a new high-modulus material has been developed and used tomodify normal road petroleum asphalt. The results from laboratory experimentsconducted at the Jiangsu Baoli Asphalt Co., LTD and real road trials inPeople's Democratic Republic of Algeria, Shanghai, Shanxi and Jiangsu provincein China, indicate that the high-modulus asphalt performed significantly betterat higher-temperatures when compared to samples of more commonly used asphaltmixtures. The high-modulus additive (No. ZQ-1) was prepared in Jiangsu BaoliAsphalt Co. LTD, and the basic production process, the basic properties as wellas the effection to base bitumen was analysed in the paper. And the DynamicStability was evaluated using an automated rut-depth measuring system. Thewater stability and low temperature properties were also discussed. Themodified asphalt material has comparable storage and usage costs to existingutilized asphalts though with enhanced high-temperature properties.
