Technical Field
The invention belongs to the technical field of road repair, and particularly relates to a regenerated pavement with excellent rut cracking resistance and a preparation method thereof.
Background
The asphalt pavement is a main structural type of the highway pavement due to the advantages of excellent driving comfort, strong skid resistance, better durability, easy construction, convenient maintenance and the like. At present, the traffic time of domestic asphalt pavements reaches two or two decades, some asphalt pavements are even longer, large-area pavement damage occurs on many pavements, and the problem is difficult to fundamentally solve by the existing maintenance and repair method. And the pavement regeneration provides a good solution, the pavement regeneration not only avoids the pollution caused by the waste of the existing pavement waste materials, but also can effectively solve the resource, and compared with paving a new road, the pavement regeneration is more green, economic and environment-friendly.
At present, the asphalt pavement regeneration mainly comprises hot regeneration and cold regeneration. The heat regeneration has the advantages that the paved road surface has the performance close to that of a new road surface, but the engineering quantity is large, the construction period is long, and the cost is high. In addition, in the existing pavement thermal regeneration, whether plant-mixed thermal regeneration or in-situ thermal regeneration, the high-low temperature performance of the mixture after thermal regeneration is reduced compared with that of the pavement without thermal regeneration, when the mixing amount of an original pavement material (RAP) reaches 40%, the low-temperature performance and the fatigue performance are obviously reduced, and the high-temperature performance is also reduced, so that in the existing thermal regeneration method, the mixing amount of the RAP material is less than 30%, the original purpose of recycling waste resources is difficult to realize completely, and the waste resources can be recycled only partially. Compared with hot regeneration, cold regeneration can effectively improve the low-temperature performance of the regenerated pavement, but the effect of the cold regenerated pavement is greatly influenced by emulsified asphalt, the high-temperature performance of a plurality of cold regenerated mixtures is not high, particularly, the waterproof performance and the anti-skid performance are not good, a layer of finish coat is often required to be additionally paved on the cold regenerated pavement, and the engineering quantity is increased invisibly.

3) heating a certain amount of the stone material in a 60 ℃ oven to constant weight to obtain water content x;
4) determining the water consumption of the regeneration mixture and the use amount y of the super absorbent resin polyacrylate according to the water content;

7) spreading the regenerated mixture on the road surface, leveling and compacting by using spreading equipment, after the spread regenerated mixture is completely cured, spraying a sand-containing fog seal layer on the surface of the mixture, wherein a binder B used for the sand-containing fog seal layer consists of cationic emulsified asphalt, nonionic aqueous epoxy resin emulsion and aqueous epoxy curing agent, the solid content of the cationic emulsified asphalt is 65%, the solid content of the aqueous epoxy resin in the nonionic aqueous epoxy resin emulsion is 50%, and the aqueous epoxy resin emulsion is an aqueous epoxy resin emulsionThe solid content of the epoxy resin curing agent is 50%, and the total mass ratio of the cationic emulsified asphalt to the nonionic aqueous epoxy resin to the aqueous epoxy curing agent is 2-4: 1, the carborundum with the size less than 2mm accounts for 10 percent of the binder B, and is paved on the binder B with the paving amount of 1-1.2 kg/m2And after the binder B is completely dried and cured, the regenerated pavement with excellent fracture resistance is obtained.
According to the preparation method of the regenerated pavement with excellent rut cracking resistance, the using amount y of the super absorbent resin polyacrylate is 10% of the water content in the binder A.
