Problems solved by technology

The existing cold-mix asphalt has good performance, but when it is applied to permeable pavement materials, its adhesion is poor, it is prone to cracking, and its durability is not good
The existing CN201610218818.X Chinese patent provides a method for preparing a binder for cold-mix colored permeable asphalt, which improves the cohesive force and durability of cold-mix permeable asphalt. However, it is found in actual implementation tests that if necessary If the adhesion and durability of cold-mix permeable asphalt meet the technical standards, the water permeability will be greatly reduced, and sufficient water permeability, adhesion and durability cannot be maintained at the same time.

Embodiment 1

[0012] The present invention proposes a kind of cold-mix permeable asphalt, which uses a cementitious material, and the cementitious material comprises 75% by weight of one-component polyurethane and 25% by weight of EVA, wherein the one-component polyurethane comprises the following raw materials by weight: 17.8% of 210 polyester polyol, 24.9% of isocyanate, 58.6% of methylene chloride, 0.08% of resin. The resin comprises 0.01% by weight of ethylenediamine and 0.03% by weight of diethanolamine. The cold-mix permeable asphalt of the present invention, the preparation method of the cement used in the cold-mix permeable asphalt comprises the following steps: 1) the preparation of one-component polyurethane: take 210 polyester polyol and part of methylene chloride and add it to the reaction kettle , after heating to 50°C under stirring, slowly add isocyanate into the reaction kettle dropwise, continue stirring and then add the remaining dichloromethane; after stirring evenly, slo...

Abstract

The invention belongs to the technical field of road paving materials, and particularly relates to cold-mixed permeable asphalt. According to the cold-mixed permeable asphalt disclosed by the invention, a cementing material is used, the cementing material is prepared from the following raw materials in parts by weight: 75 to 80 percent of single-component polyurethane and 15 to 25 percent of EVA (Ethylene Vinyl Acetate), and the single-component polyurethane is prepared from the following raw materials in parts by weight: 17.8 to 23.2 percent of 210 polyester polyol, 18.5 to 24.9 percent of isocyanate, 52.2 to 58.6 percent of dichloromethane and 0.08 to 0.15 percent of resin. All indexes of the cementing material for the cold-mixed colored permeable asphalt prepared by adopting the cold-mixed permeable asphalt and the method disclosed by the invention reach or exceed national standards, and the permeable asphalt produced by adopting the cementing material has more excellent durability, rutting resistance and the like.

Description

technical field [0001] The invention relates to the technical field of asphalt, in particular to cold-mix permeable asphalt. Background technique [0002] Cold mix asphalt is used in a wide variety of applications, often as paving materials. The existing cold-mix asphalt has good performance, but when it is applied to permeable paving materials, it has poor cohesive force, is prone to cracking, and has poor durability. The existing CN201610218818.X Chinese patent provides a method for preparing a binder for cold-mix colored permeable asphalt, which improves the cohesive force and durability of cold-mix permeable asphalt. However, it is found in actual implementation tests that if necessary If the adhesion and durability of cold-mix permeable asphalt meet the technical standards, the water permeability will be greatly reduced, and sufficient water permeability, adhesion, and durability cannot be maintained at the same time. Contents of the invention [0003] The object of...
