| Abstract: | Standard Marshall test, freeze-thaw splitting test and rutting test are carried out to test the water stability and high temperature stability of steel fiber asphalt concrete with different mixing proportions, and optimum fiber mixing proportion and asphalt-aggregate ratio are determined. The mixing, paving and compacting techniques are studied in combination with on-site construction of steel fiber asphalt mixture. Years of application shows that the steel fiber concrete is of favourable anti-rut and anti-crack capabilities. |
