Abstract

The invention discloses epoxy asphalt for a gravel sealing layer, a gravel sealing layer material and a gravel sealing layer method. The epoxy asphalt for the gravel sealing layer is prepared from the following raw materials by weight percent: 50.0%-80.0% of epoxy resin, 10.0%-30.0% of curing agent, 5.0%-15.0% of asphalt and 5.0%-15.0% of additive, wherein the epoxy resin is bisphenol A type epoxy resin; the curing agent is prepared from polyamide and triethylene tetramine or diethylene triamine at a weight ratio of 2:1; the additive is phthalate; and the asphalt is No.70 paving asphalt. The invention also discloses the gravel sealing layer material which is prepared from the epoxy asphalt and gravel at a weight ratio of 1:(3-5) and the gravel sealing layer method of the gravel sealing layer material. By adopting the epoxy asphalt, the adhesive property of asphalt can be increased and the gravel on a asphalt pavement can be prevented from coming off.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to an epoxy asphalt for a gravel seal, a gravel seal material and a gravel seal method. Background technique [0002] The asphalt surface layer of high-grade highway pavement requires good water tightness, high temperature shear deformation resistance, and skid resistance. Long rock etc. are widely used in asphalt surface layer. On the other hand, the asphalt surface layer generally adopts a dense skeleton mineral aggregate gradation, which is characterized in that the amount of 3-5mm crushed stones in the mineral aggregate gradation only accounts for less than 10%. According to this calculation, my country builds 8,000 kilometers of expressways every year, and the asphalt surface layer has a surplus of basic rocks of 3-5 mm and more than 2 million tons of crushed stones. At present, the country is vigorously developing the circular economy and building a resource-saving ...
