Abstract

The invention relates to an electromagnetic induction type thermally dispersed PAN-PE composite modified stone mastic asphalt material, a preparing method thereof and a constructing method of the material. The material is prepared by mixing and stirring polyoxyethylene alkyl ether, silicone oil and water to prepare a dispersing agent, mixing polyaniline and polyethylene to prepare an electromagnetic induction type PAN-PE compound polymer modifying agent, adding the modifying agent into matrix asphalt, stirring, mixing, shearing, blending weighed aggregate and lignin fibres, blending the PAN-PE compound modified asphalt, the aggregate and the lignin fibres, adding the dispersing agent and a warm-mix agent, adding ore powder, blending, and discharging from a kettle to obtain the material. The material can be used for local damage repair of SMA pavements of bridge floors, tunnels, airports and highways of various grades, is capable of pre-mixing, free of blocking and capable of long-term storage, is a high-performance hot-repair material that can be heated when the material is to be used for pits and slots, is suitable for repairing SMA type pavements and fully matches original pavements.

Description

technical field [0001] The invention relates to a repairing material for local damage on asphalt pavement, in particular to an electromagnetic induction thermal discrete PAN-PE composite improved asphalt mastic macadam material and its preparation method and construction method. Background technique [0002] For asphalt pavement, water damage is a typical form of disease, especially during construction, mixture temperature segregation, aggregate segregation, and insufficient compaction can cause local water seepage in the pavement. When the load is applied, the seepage water is squeezed out, and when the load is unloaded, the water is sucked in again, and the strong dynamic water pressure caused by the pumping action will repeatedly wash the surface of the asphalt mixture and the semi-rigid base layer, resulting in the pumping phenomenon; with the mud, The fine aggregate is further carried away and will eventually form potholes. [0003] At present, there are two main maint...
