Study on Properties of High Performance and High Viscosity Modified Asphalt
Based on practical projects,the application of high performance and high viscosity modified as-phalt in road construction was studied.Starting from the selection of raw materials,the needle penetration,softening point and viscosity of HVA-H high viscosity modified asphalt,HVA high viscosity modified as-phalt and powder high viscosity modified asphalt were respectively tested to study their fluidity,tempera-ture sensitivity,plasticity,and viscosity.The test results show that the temperature sensitivity,fluidity,plas-ticity,and viscosity of HVA-H are the best.HVA-H can be used as a high viscosity modifier in the con-struction process.
