Application and Evaluation of NovaSurfacing Technology

In order to solve the problems of poor adhesion and durability at conventional micro surfaces, The process of spraying modified emulsified asphalt, paving and mixing super-abrasive layer containing glass fiber, novasurfacing are used. The SCB semi-circular bending test compares the performance comparison between the novasurfacing and the conventional micro-surfacing. The coefficients of friction, flatness, and PCI are used to compare the performance changes before and after the repair of the road section. Use the net annual value method to evaluate its economic benefits. The results show that the supervised abrasion layer has advantages in both performance and economic benefits.
