Abstract
The invention discloses a method for preparing a plant asphalt-based road surface reclaiming agent. The reclaiming agent prepared through the method has very high compatibility with asphalt. The method comprises the following steps: (1) throwing the viscosity modifier and the antioxidant into a reaction kettle, pumping the base oil into the reaction kettle by using a pump, stirring, heating to 80 to 100 DEG C, and stirring for 2 to 4 hours, wherein the stirring speed is 80 to 130 rpm, and the base oil is required to be heated to 60 to 80 DEG C and pumped out by using the pump during winter production; (2) storing the plant asphalt in a storage tank at the constant temperature of 130 DEG C, pumping the plant asphalt into the reaction kettle by using the pump according to the weight, controlling the reaction temperature to be 80 to 100 DEG C, stirring for 1 to 3 hours at the stirring speed of 80 to 130 rpm, and naturally cooling. When the plant asphalt is used on site, a reclaiming agent material is directly thrown into the recycled asphalt material during on site use, and the using amount of the plant asphalt is 5 to 30 percent of the recycled asphalt material.
Description
Technical field
The present invention relates to a kind of method preparing pavement recycling agent based on plant asphalt.
Background technology
Plant asphalt is to extract warp in edible oil, biodiesel, fatty acid production and pulping wood paper-making process
Cross the by-product produced after various operation processes, therefore be also classified into Oleum Glycines drip according to the plants Colophonium extracting oil
