Problems solved by technology

[0004] However, the relatively simple preventive maintenance method of fog seal layer commonly used at present, its biggest disadvantage is that the anti-seepage effect is not ideal, and the adhesion between the original fog seal layer and the original pavement stone material cannot achieve the expected effect. Detachment will occur, exposing the stone material of the original pavement, and the anti-seepage ability of the pavement will be reduced, thereby reducing the skid resistance of the surface layer of the asphalt pavement

Abstract

The invention relates to the technical field of highway maintenance, and discloses an oily enhanced fog seal material for asphalt pavement, a preparation method and a construction method. The material of the fog sealing layer includes a waterproof and permeable lower sub-layer and an anti-skid and wear-resistant upper sub-layer, and the upper and lower sub-layers are respectively composed of the emulsion material of this layer and sand material. The emulsion material of the lower sub-layer contains petroleum asphalt, solvent naphtha, oily penetrant, tackifier, and additives, and the emulsion material of the upper sublayer contains petroleum pitch, solvent naphtha, oily penetrant, tackifier, additive, and anti-ultraviolet aging agent. The construction method of the fog seal layer material is the layered spreading method: mix the emulsion material of the lower sub-layer with sand and spread it on the asphalt pavement to form a waterproof and permeable lower sub-layer, and then spray the emulsion material of the upper sub-layer on the waterproof and permeable surface after drying. On the lower sub-layer, then spread sand material to form the anti-slip and wear-resistant upper sub-layer. The invention is used for the preventive maintenance of the road surface, and can improve the water resistance, skid resistance, fastness and anti-ultraviolet aging performance of the road surface.

Description

technical field [0001] The invention relates to the technical field of highway maintenance, in particular to an oily enhanced fog seal material for asphalt pavement, a preparation method and a construction method. Background technique [0002] After several years of normal use of the asphalt pavement, the pavement will experience slight fatigue cracks and loss of fine aggregates, and its anti-seepage performance will deteriorate, and pavement water will enter the asphalt mixture through cracks or fine aggregate damage. accelerated road damage. [0003] Fog seal is currently the most effective preventive maintenance measure for asphalt pavement. This technology spreads the fog seal material on the asphalt pavement in the form of a mist to form a thin layer of seal to seal tiny cracks and surfaces. Voids, restore and protect the oxidized asphalt pavement, play a role in waterproofing and inhibiting looseness, and at the same time improve and enhance the image of the pavement....
