Problems solved by technology

[0006] In order to solve the problem that the emulsified asphalt penetrating oil in the prior art has a good penetration effect on the newly built semi-rigid base, but the surface porosity gradually decreases with time, and the denser old semi-rigid base has a permeability problem. Technical problem, the application provides a high-permeability emulsified asphalt penetration layer oil, the raw materials used are asphalt, emulsifier, and mixed with high-permeability composite light components and high-dose stabilizers to enhance the permeability and cohesion of the penetration layer, Spray the highly permeable emulsified asphalt material evenly on the road base in a uniform way to improve the integrity of the road surface and achieve the effect of improving the service life of the road surface

Embodiment 1

[0034] A high-permeability emulsified asphalt material, also known as high-permeability emulsified asphalt oil penetration, is made of the following raw materials in parts by weight: 45 parts of petroleum asphalt, 3 parts of emulsifier, 40 parts of water, 7 parts of kerosene, 3 parts of furfural oil, and 2 parts of additives share. Among them, the emulsifier is MQK-1M emulsifier, and the additive is CaCl 2 .

[0035] Its preparation method is as follows:

[0036] Step 1: Prepare various raw materials according to the above-mentioned high-permeability emulsified asphalt material ratio;

[0037]Step 2: Add the emulsifier to water at about 60°C, adjust the pH value to 3.0 with a pH regulator (35% HCl solution), and add additives to further dissolve the emulsifier. After fully dissolving, stir evenly, and then use hydrochloric acid again adjusting the pH value of the mixed liquid to 3.0 to prepare the mixture;

[0038] Step 3: After heating and melting 45 parts by weight of as...

Embodiment 2

[0045] A high-permeability emulsified asphalt material is composed of petroleum asphalt, emulsifier, water, permeable composite light components and additive raw materials. The percentage by weight of each raw material is: 42 parts of petroleum pitch, 2 parts of emulsifier, 40 parts of water, 10 parts of kerosene, 5 parts of furfural oil, and 1 part of additive. Among them, the emulsifier is MQK-1M emulsifier, and the additive is CaCl 2 .

[0046] The specific implementation process is basically the same as in Example 1, the difference is that in step 3, 42 parts by weight of asphalt is heated and melted to 140 ° C, mixed with 15 parts by weight of permeable composite light components; in step 4, it is 43 parts of aqueous solution and 57 parts by weight Part of the molten mixture was added to a colloid mill shearing machine for grinding for 3 minutes; the construction spraying temperature in step 6 was 90°C.

Embodiment 3

[0048] A high-permeability emulsified asphalt material is composed of petroleum asphalt, emulsifier, water, kerosene and additive raw materials. The percentage by weight of each raw material is: 40 parts of petroleum pitch, 1.8 parts of emulsifier, 47.9 parts of water, 10 parts of kerosene, and 0.3 part of additive. Among them, the emulsifier is a quaternary ammonium emulsifier, and the additive is CaCl 2 .

[0049] The specific implementation process is basically the same as that of Example 1, except that: in step 3, 40 parts by weight of asphalt is heated and melted to 140°C, and mixed with 10 parts by weight of permeable composite light components; in step 6, the construction spraying temperature is 90°C.

Abstract

The invention provides high-permeability emulsified asphalt permeable oil as well as a preparation method and application thereof. A spraying mode is adopted on an asphalt pavement, and a high-permeability emulsified asphalt material comprises the components in parts by weight: 40-50 parts of petroleum asphalt, 1-5 parts of an emulsifier, 35-45 parts of water, 10-15 parts of a permeable compositelight component and 1-2 parts of an additive. The application method comprises the steps: uniformly spraying the obtained high-permeability emulsified asphalt permeable oil on a pavement base, spraying seal coat asphalt after drying, and opening the traffic after maintenance. The material is reasonable in design, has good infiltration capacity, film forming effect and water seepage prevention capacity, can meet the permeability requirement of a pavement semi-rigid base layer, and improves the overall performance of a pavement. Most components in the raw materials of the material are functionalraw materials, so that the material has good economic benefits, is free of pollution and has good social benefits. The high-permeability emulsified asphalt is used for a permeable layer of a pavement, and can reduce the cost and protect the environment while meeting the use performance of the pavement.

Description

technical field [0001] The application belongs to the technical field of new road construction and maintenance construction, and relates to the application technology of a pavement penetrating layer, in particular to a high-permeability emulsified asphalt penetrating oil and its preparation method and application. Background technique [0002] The asphalt pavement penetration layer is an important basis for ensuring good bonding between the cement-based stable base and the asphalt surface layer, and it mainly plays a bonding role. As a semi-rigid base, the cement-based stable base will gradually decrease in surface porosity as time goes on, making it denser and making it difficult for the permeable oil to penetrate. However, whether the permeable layer can penetrate to a certain depth on the surface of the cement-based stable base depends It plays an important role in enhancing the integrity of the semi-rigid base and asphalt layer and prolonging the service life of the pave...
