Asphalt regenerant that can be recycled multiple times and its preparation method and application process

Abstract

The invention provides a recyclable asphalt regenerant as well as a preparation method and an application process thereof. The asphalt regenerant is prepared from the following raw materials in percentage by mass: 3.2% of epoxy resin, 4.6% of waste engine oil and 92.2% of 90# asphalt. The recyclable asphalt regenerant is prepared by using the 90# asphalt, and is simple in preparation process is simple, rich in raw material source, and economic and practical; an aging regeneration test on 70# road asphalt indicates that the asphalt regenerant has excellent regeneration function, and the regenerated asphalt is stable in quality, capable of meeting the existing standard requirements in various technical indexes, and therefore, a regenerant is provided for multiple recycling of asphalt pavements.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an asphalt regenerant which can be recycled multiple times and its preparation method and application process. Background technique [0002] The prosperity and development of our country's economic level has brought rapid progress in the transportation industry. As the main pavement form of expressways in my country, asphalt pavement has been widely used because of its outstanding road performance, low noise and good flexibility. According to statistics from the construction of roads in our country, by the end of 2012, the mileage of highways that have been repaired and opened to traffic has increased rapidly, reaching 4,237,500 kilometers, of which 96,200 kilometers belong to the mileage of expressways. Attention is paid to transportation facilities, and the annual road construction is basically supported by more than 200 billion yuan of national finance. However, the service ...

AI Technical Summary

Problems solved by technology

As the asphalt pavement ages, cracks, looseness, and potholes will appear on the pavement, which will have a relatively large negative impact on the road performance of the road.

Many expressways built in the 1990s will inevitably enter the stage of one or two major and medium renovations with the arrival of their design years, so a large amount of waste asphalt will be produced on the old road surface, which wastes limited natural resources. At the same time, it has produced a lot of pollution to the precious natural environment, and the economic benefits will be reduced correspondingly to a large extent.
