[Abstract]:At present, a large number of highways in our country have entered the maintenance and repair period. If effective measures are not taken in time to deal with the early diseases such as cracks, loose and polished, it will lead to more serious damage to the road surface and reduce the level of highway service. Even endangering the safety of driving. Microsurfacing is a kind of preventive maintenance method which can quickly solve the early disease of road surface and restore surface function. It is widely used at home and abroad, but the road performance of the existing micro-surfacing materials. The durability and interlaminar bond properties need to be further improved. In order to improve the preventive maintenance effect of micro-surfacing mixture and prolong the service life of pavement, the waterborne epoxy resin emulsified asphalt was used to obtain a road performance in this paper. Both durability and interlaminar shear strength are superior to ordinary microsurfacing mixtures. In this paper, the formation mechanism, demulsification mechanism and preparation process of modified emulsified asphalt are analyzed and summarized. The emulsified asphalt was designed with cationic emulsifier and organic stabilizer, and the emulsified asphalt could be stably stored. The curing mechanism and modification mechanism of waterborne epoxy resin were analyzed. The effect of waterborne epoxy resin on the properties of emulsified asphalt was studied by dynamic shear rheological test. The mixture ratio of micro-surfacing mixture was designed, and the selection range of emulsified asphalt was determined. In this range, the effects of waterborne epoxy resin on wear resistance, rutting resistance and peeling resistance of micro-surface were studied. Based on the wet wheel wear test for 6 days, the influence of water-borne epoxy resin and oil stone ratio on the water stability of microsurfacing was analyzed by combined with freeze-thaw cycle wet wheel wear test. The wear resistance and long term wear resistance of waterborne epoxy microsurfacing were analyzed by accelerated loading wear test. Shear test was used to study the interlaminar shear resistance of waterborne epoxy microsurfacing with asphalt pavement and cement pavement. At the same time, it is compared with SBR modified emulsified asphalt microsurfacing mixture. Finally, the factors affecting the construction performance of micro-surfacing mixture are studied. The results show that with the increase of the amount of waterborne epoxy resin, the composite shear modulus of the evaporative residue of emulsified asphalt increases gradually, the phase angle decreases, and the performance is improved. When the dosage of waterborne epoxy resin is between 8% and 11%, the pavement performance, water stability, skid resistance and long term wear resistance of microsurfacing can be improved obviously, and it has obvious advantages over SBR microsurfacing, compared with SBR modified emulsified asphalt. Using waterborne epoxy emulsified asphalt as the adhesive material can make the interlaminar shear strength stronger at the micro-surface with small amount of sprinkling.
