Description
Technical Field
The invention belongs to the technical field of highway maintenance, and particularly relates to a full basalt micro surfacing material and a preparation method thereof.
Background
At present, most roads in China enter a maintenance period in succession, and as the traffic volume of heavy vehicles is increased day by day, the traffic load pressure is heavier, the anti-skid performance of a plurality of road surfaces is obviously insufficient, the abrasion of road surfaces is serious, and the anti-skid performance of the road surfaces is insufficient. The traditional micro-surfacing technology generally selects limestone, the strength of the limestone is low, the anti-skid performance of the limestone is quickly attenuated under the repeated rolling of wheels, and the anti-skid requirement of an asphalt pavement cannot be met, so that the mineral aggregate with good anti-skid performance is urgently needed to be prepared for micro-surfacing. Because the basalt has the advantages of high strength and good durability, the skid resistance and durability of the asphalt pavement can be comprehensively improved by preparing the full basalt micro-surfacing, but because the basalt is weak in alkalinity and poor in cohesiveness with asphalt, the basalt is difficult to wrap by common emulsified asphalt.
The invention discloses emulsified asphalt and a preparation method thereof, and a stable and durable cement pavement slurry seal lower seal and a preparation method thereof, wherein the prepared slurry seal mixture is spread on a formed rigid base layer lower bearing layer to form a slurry seal lower seal, wherein the slurry seal mixture is prepared from 99 parts of mineral aggregate, 1 part of cement, 10-15 parts of emulsified asphalt and 8-10 parts of water, and the emulsified asphalt is prepared from SBR modified emulsified asphalt, water-based epoxy resin and water-based epoxy curing agent, wherein the SBR modified emulsified asphalt has good adhesion property with aggregate, and is applied to the cement pavement slurry seal lower seal to remarkably enhance the dynamic water scouring resistance of the slurry seal mixture and has excellent stable and durable properties. Although the water-based epoxy asphalt is used for modifying the emulsified asphalt to prepare the emulsified asphalt slurry seal, the water-based epoxy asphalt has poor flexibility and high brittleness, so that the emulsified asphalt slurry seal is only suitable for the lower seal of the cement pavement slurry seal and is easy to break when being used on the surface layer.
The Chinese patent with the patent application number of CN201910041266.3 discloses a cold-mixing cold-paving anionic emulsified asphalt and a preparation method and application thereof, wherein the raw materials comprise mineral aggregate, cement, externally-doped water and modified emulsified asphalt, the optimal oilstone ratio of the emulsified asphalt mixture is 4-5%, the dosage of the externally-doped water is 1-2% of the mass of the mineral aggregate and the cement, the dosage of the cement is 1-2% of the total mass of the mineral aggregate and the cement, the raw materials for preparing the modified emulsified asphalt comprise the emulsified asphalt and a modifier waterborne epoxy resin, the dosage of the modifier waterborne epoxy resin is 10-15% of the mass of the emulsified asphalt, and the raw materials of the modifier waterborne epoxy resin comprise the waterborne epoxy resin and a curing agent; the raw materials of the emulsified asphalt comprise emulsifier, water, stabilizer solution and matrix asphalt, wherein the dosage of the emulsifier accounts for 1.2-4.0% of the emulsified asphalt. The dynamic stability, the residual stability and the maximum bending-pulling failure strain of the cold-mixing cold-paving anion modified emulsified asphalt mixture accord with technical specifications for highway asphalt pavement construction (JTG F40-2004) and corresponding technical requirements of engineering, but the emulsified asphalt prepared by the invention has larger brittleness due to the addition of epoxy resin with poorer flexibility, and the cold-mixing cold-paving anion modified emulsified asphalt mixture is only suitable for a structural layer of a cold-mixing cold-paving pavement and cannot be applied to preventive maintenance of asphalt pavements such as micro-surfacing and the like.
