Problems solved by technology

Traditional asphalt pavement maintenance adopts the method of excavating the surface layer and base layer and then re-paving. Not only the cost of reconstruction is high and the construction period is long, but also the remaining value of the milled asphalt pavement materials cannot be fully utilized.
The existing technology cannot recycle the asphalt in the recycled aspha...

Abstract

The invention discloses a reproducible asphalt mixture and a preparation method thereof. The reproducible asphalt mixture is prepared from waste road petroleum asphalt, waste engine oil, pulverized fuel ash, cerous chloride, zirconium dioxide, polyethylene glycol, epoxy resin E-44, ethyl carbamate and phthalate. The preparation method comprises the following steps of firstly performing heating, stirring and uniform mixing on the waste road petroleum asphalt, the pulverized fuel ash, the waste engine oil, the polyethylene glycol and the epoxy resin; then, adding other ingredients for normal temperature stirring and uniform mixing; obtaining the reproducible asphalt mixture through preparation. By adding modifying agents into the waste road petroleum asphalt, the reproducible asphalt mixture with the improved performance is obtained. The preparation method is simple; the waste asphalt can be reproduced at a low temperature; the reproduced asphalt has good performance; the energy saving, emission reduction and environment protection are facilitated.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a renewable asphalt mixture and a preparation method thereof. Background technique [0002] The aging of asphalt is due to the volatilization, polymerization, dehydrogenation and other effects of light oil. Among them, the oxidation of various components in asphalt occurs, that is, the chemical reaction with oxygen in the air occurs. The degree of oxidation of asphalt is related to the temperature. The higher the temperature, the faster the oxidation, which means the faster the aging of asphalt. This is why the aging of asphalt mixture is particularly serious when it is mixed at high temperature. Studies have shown that when asphalt is in contact with burning gravel in a thin film state at a high temperature of 160°C to 170°C, its aging rate is almost equivalent to the aging of asphalt pavement in a natural state for 19 years. The higher the temperature, the more i...
