Problems solved by technology

However, the performance of the existing asphalt pavement reducing agent to restore and activate asphalt aging is still insufficient, and the service life of the asphalt pavement is not significantly extended. The composition and color of the initial pavement are maintained, and the asphalt pavement reducing agent can ensure the durability of the road surface. In addition, the asphalt pavement reducing agent of the present invention has the advantages of low price and convenient construction.

Embodiment 1

[0017] The asphalt pavement reducing agent of the present invention comprises the following components: 25 parts of zinc-enriching agent, 15 parts of styrene-butadiene latex, and 60 parts of xylene.

[0018] The zinc-enriching agent consists of 45 parts of zinc powder, 30 parts of water-based epoxy, and 0.6 part of polyurethane.

[0019] The preparation method adopts the following steps:

[0020] 1. Heat 30 parts of water-based epoxy to a liquid state, and add 45 parts of zinc powder and 0.6 parts of polyurethane to it, and then uniformly dissolve to prepare 25 parts of zinc-rich agent.

[0021] 2. Rinse the funnel of the high-speed shearing instrument with an appropriate amount of hot water in advance, and then close the water outlet valve;

[0022] 3. Pour the uniformly mixed solution in step 1 into the funnel of the high-speed shearing instrument, turn on the switch of the high-speed shearing instrument, and add 15 parts of styrene-butadiene latex evenly to it at the same ...

Embodiment 2

[0025] The asphalt pavement reducing agent of the present invention comprises the following components: 22 parts of zinc-enriching agent, 13 parts of styrene-butadiene latex, and 65 parts of xylene.

Embodiment 3

[0027] The asphalt pavement reducing agent of the present invention comprises the following components: 20 parts of zinc-enriching agent, 15 parts of styrene-butadiene latex, and 65 parts of xylene.

[0028] Examples 2 and 3 adopt the same preparation method as that of Example 1 to obtain asphalt pavement reducing agent.

Abstract

The invention discloses an asphalt pavement reducing agent material, which comprises components A, B and C, wherein component A consists of 40 to 50 parts by mass of zinc powder, 20 to 40 parts by mass of waterborne epoxy resin and 0.2 to 0.8 part by mass of polyurethane; component B consists of 60 to 65 parts by mass of a dimethylbenzene solution; component C consists of 10 to 15 parts by mass of styrene-butadiene latex. A high-speed shearing and low-speed development preparation process is adopted. The asphalt pavement reducing agent material is low in cost, and has broad market application prospect, a construction process is simple, and the problem of driving dangers caused by long-term wear and oxidization of a pavement can be solved.

Description

technical field [0001] The invention relates to a reducing agent material for asphalt pavement, which belongs to the technical field of road materials. Background technique [0002] At present, asphalt pavement is widely used in road construction in our country, and most of the highways built in our country are asphalt pavement. Asphalt pavement has many advantages such as good driving stability, short construction period, and easy maintenance and repair. However, asphalt mixture is greatly affected by temperature, and aging will occur after long-term use, and it will be oxidized by air and moisture to asphalt pavement. And water damage, coupled with the long-term load of vehicle tires and asphalt pavement, the asphalt pavement will be damaged earlier, which will affect the service performance and life of the asphalt pavement. The asphalt pavement reducing agent preventive maintenance technology is a maintenance measure that sprays the pavement reducing agent on the asphalt...
