Embodiment 1

[0037] 1. Use a rubber cutter to cut the block carbon dioxide copolymer raw material with a number average molecular weight of 30,000-160,000 into blocks with a diameter of less than 8cm, and then use a pulverizer to crush the cut block carbon dioxide copolymer into particles, so that Its diameter is less than 3mm; use a pulverizer to crush the scraps of carbon dioxide copolymer medical dressing into fragments, so that its area is less than 25mm 2 .

[0038] 2. Use an electronic scale to weigh 30kg of carbon dioxide copolymer raw material particles, 50kg of carbon dioxide copolymer medical dressing scraps, 200kg of ethyl acetate (or dimethyl carbonate), 2kg of basalt fiber, 1kg of carbon fiber, 5kg of rice straw fiber, and 5kg of corn straw fiber. Straw fiber 5kg, nano silicon dioxide 2kg. Open the stirring tank, stir at 300r / min, first pour ethyl acetate (or dimethyl carbonate) into the stirring tank, under the condition of stirring, add 30kg of carbon dioxide copolymer raw ...

Embodiment 2

[0043] The pavement regeneration was carried out in the same way as in Example 1, except that the composition ratio of the regeneration agent was different. (See Table 1)

Abstract

The embodiment of the invention discloses a pavement regeneration agent, which comprises the following components by weight: 50-100 parts of carbon dioxide copolymer; 10-20 parts of fiber material; 1-5 parts of nanofiller. The present invention also discloses the preparation method of the road rejuvenation agent, the method comprises the following steps: 1) pulverizing the carbon dioxide copolymer and dissolving it in a solvent to form a solution A, wherein the solvent is ethyl acetate or carbonic acid Dimethyl ester; 2) mix the fiber material and the nanofiller, add the solution A obtained in the step 1), and stir together to form the mixture B. The invention also discloses a method for using the road surface regeneration agent to regenerate the diseased road surface.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of road restoration, in particular to a road regeneration agent and its preparation method and application. Background technique [0002] At present, domestic roads are mainly asphalt roads and cement roads. Most of the asphalt roads have been open to traffic for ten years or more. However, asphalt roads are prone to aging due to environmental factors such as sunlight, rain and temperature changes. As a result, problems such as rutting, cracks, looseness, and potholes will occur on the asphalt pavement during service, especially in the context of modern traffic heavy load, large flow, and channelization. Timely maintenance is very important. At present, there are two main types of asphalt pavement regeneration: hot regeneration and cold regeneration. The high and low temperature performance and fatigue performance of the heat-regenerated mixture are lower than those of the non-heat...
