Embodiment Construction

[0030] This embodiment is the best embodiment to provide the applicant with finalization and further promotion, and is used to further describe the present invention in detail, but it is not intended to limit the protection scope of the present invention.

[0031] (1) Preparation of environment-friendly asphalt regenerant:

[0032] First waste engine oil (mass percentage is 25%) is fully mixed with 40 purpose waste rubber (mass percentage is 20%), furfural extract oil (mass percentage is 48%), adds peptizer after normal temperature swelling 30min (mass percentage is 0.5%), fully stirred evenly to obtain a mixed solution; then the mixed solution was put into an Erlenmeyer flask, plugged with a ground glass stopper with small holes, put into a microwave processor, selected a microwave power of 450w, and treated with microwave irradiation for 3min, took out, Stir evenly and cool down, repeat the microwave treatment operation 3 times; when the temperature of the mixed solution aft...

Abstract

The invention relates to asphalt reclaiming agents and particularly discloses an environment-friendly asphalt reclaiming agent and a preparing method and a using method thereof. The environment-friendly asphalt reclaiming agent is prepared from, by mass, 15-30% of waste engine oil, 15-25% of waste rubber powder, 45-55% of aromatic light oil, 0.1-1% of a petizing agent, 3-8% of petroleum resin and 0.1-0.5% of an anti-ageing agent. The preparing method of the environment-friendly asphalt reclaiming agent comprises the steps that the waste engine oil, the waste rubber powder and the aromatic light oil are mixed, the petizing agent is added after swelling is achieved at the normal temperature, the mixture is stirred evenly, and a mixed solution is obtained; the mixed solution is subjected to microwave irradiation, and a thick solution is obtained; finally, the petroleum resin and the anti-ageing agent are added into the thick solution, the mixture is mixed evenly, and the environment-friendly asphalt reclaiming agent is obtained. The adding quantity of the environment-friendly asphalt reclaiming agent accounts for 7-9% of waste asphalt by mass when the environment-friendly asphalt reclaiming agent is used for reclaiming waste asphalt pavements. The raw material ingredients are low in price, cost of the raw materials is reduced, and environment production is facilitated.

Description

technical field [0001] The invention relates to an asphalt regenerant, in particular to an environment-friendly asphalt regenerant and its preparation method and use method. Background technique [0002] Under the comprehensive action of traffic load and natural factors, asphalt pavement will have various diseases and gradually expand until it cannot be used normally. According to the design life of the asphalt pavement and the actual use conditions, the asphalt pavement needs to be renovated every 10-15 years, that is, the old pavement is removed and a new asphalt pavement is paved again. According to rough calculations, China discards more than 2 million tons of road asphalt mixture every year, including more than 100,000 tons of asphalt. It can be predicted that as the road mileage increases year by year, the waste mixture will also increase year by year. If these large quantities of waste mixtures cannot be recycled in time and effectively, it will not only cause waste ...
