The development of the fog sealing technology in China is relatively late, and the research on corresponding fog sealing materials is lacked. The preventive maintenance material for the fog sealing layer can be divided into the following materials according to different properties: common emulsified asphalt, modified emulsified asphalt, regenerants, combinations of the above materials and the like. The common emulsified asphalt is limited in use in a large amount due to single performance, and the regenerant has good service performance but relatively high price, so that the maintenance cost is increased. With the increasing maturity of the development technology of the modified emulsified asphalt, the modified emulsified asphalt is applied to the fog sealing layer maintenance technology, plays a better role, is widely concerned and has high cost performance. In addition, the existing fog sealing layer material has the problems of poor stability, poor adhesion with a road surface, poor permeability, low demulsification speed, poor waterproof effect, environmental pollution and the like in the using process.
The Fog Seal technology (Fog Seal) is a preventive maintenance technology for sealing the pores of road surface, stabilizing loose aggregate and repairing the aged road surface by spraying the fluid materials such as emulsified asphalt, modified emulsified asphalt or asphalt pavement curing agent onto the asphalt pavement mechanically (or manually brushing the materials) to form a thin protective layer on the road surface.
Based on an analysis of the fog seal principle and function, an ideal fog seal material should have or partially have the following properties:
