Gradation Design and Road Validation of High Modulus Asphalt Concrete Based on Anti Rutting Performance
Based on the functional requirements of high modulus asphalt concrete,this article conducts gradation design for fine and coarse aggregates,determines the mass ratio of the two aggregates,and then combines gradation design to obtain nine different design gradations.Through Marshall test,rutting test,low-temperature test,freeze-thaw splitting test,and boiling test,the first five more feasible design gradations and the road performance of two comparative gradation asphalt concrete are verified.High modulus asphalt con-crete has good high-temperature resistance,rutting resistance,low temperature resistance,and water stability,confirming the application value of high modulus asphalt concrete in the prevention and control of road rut-ting diseases.
