| Abstract: | The Performances of Zhonghai high viscosity and high elastic modified asphalt were evaluated by traditional tests and DSR tests. The test results showed the viscosity at 60 ℃ reached 91768 Pa.s and elastic recovery was more than 95%. Asphalt mixture also had good rutting resistance, water stability and anti crack ability in low temperature. This special modified asphalt was suitable for heavy traffic road, tunnel and airport runway. |
