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 road maintenance and discloses an oil enhanced fog seal material for asphalt pavement and a preparation method and a construction method of the oil enhanced fog seal material. The fog seal material comprises a waterproof permeable lower sublayer and a non-slip wear-resistant upper sublayer, wherein the upper sublayer and the lower sublayer are respectively composed of emulsion materials and sand on the layers; the emulsion material on the lower sublayer contains petroleum asphalt, solvent oil, an oil penetrating agent, a tackifier and an additive; and the emulsion material on the upper sublayer contains petroleum asphalt, solvent oil, an oil penetrating agent, a tackifier, an additive and an ultraviolet aging-resistant agent. The construction method of the fog seal material refers to a layered spreading method, namely mixing the emulsion material and sand on the lower sublayer and then spreading the mixture on the asphalt pavement so as to form the waterproof permeable lower sublayer, spraying the emulsion material on the upper sublayer on the waterproof permeable lower sublayer after drying, and spreading the sand so as to form the non-slip wear-resistant upper sublayer. The fog seal material disclosed by the invention is used for preventive maintenance of roads, and the water resistance, skid resistance, firmness and ultraviolet aging resistance of the pavement can be improved.

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....
