Thin wear layer technology is a new kind of preventive maintenance technology , adapt to the traffic volume , pavement performance requirements of high-grade pavement preventive maintenance , improved flatness , skid , wear-resistant , noise reduction , construction simple , fast, good durability , more and more widespread concern . In order to ensure the continuity between the layers , so that the firm adhesion of the old and the new surface layer , to prevent the wear layer delamination , should be done in the surface layer between the adhesive layer . Bond strength , stable performance , high - performance modified emulsified asphalt production , using different technology , different methods developed to make sure the sticky layer material of all kinds of raw materials , material proportioning and process , come to the first modified and then emulsification of the program is excellent, and the factors that affect the performance of the modified emulsified asphalt modifier content , emulsifier content , solid content , pH value , emulsification temperature determined by orthogonal experiment to determine the high-performance modified the emulsified asphalt optimal solution , and thus the key factors that affect asphalt pavement layer bonding effect its dose changes modified emulsified asphalt indicators modified emulsified asphalt preparation program and test validation through the mix the reasonableness of the program . As an excellent article production of high-performance modified emulsified asphalt sticky layer of material , after demulsification asphalt solid content and low viscosity can be an effective solution to the problem , and verified by experiment , the indicators are in line with regulatory requirements , and mixed material after mixing the specimen also at the same time satisfy the shear strength , anti- pull strength indicators can greatly improve the combination between the high - grade asphalt pavement layer condition .
