A kind of normal temperature asphalt modifier and application method

Abstract

The invention discloses a normal temperature asphalt modifier and an application method. The normal temperature asphalt modifier includes: a normal temperature asphalt liquefaction agent and a normal temperature asphalt curing agent, and the normal temperature asphalt liquefaction agent includes the following raw materials by weight: 60-80 parts of vegetable oil residue extract, 1-8 parts of waste rubber powder, 4 to 16 parts of potassium cocoate and 8 to 17 parts of water-based polyurethane, and the normal temperature asphalt curing agent includes the following raw materials by weight: 1 to 2 parts of grafted macromolecular water-absorbent resin and 1 to 6 parts of calcium hydroxide . The embodiment of the present invention can realize the liquefaction of asphalt at room temperature, reduce the environmental pollution and energy consumption during the production and construction of the hot mix asphalt mixture; it does not rely on solvent volatilization or demulsification to form strength, shortens the curing cycle, and reduces volatilization pollution. It is beneficial to environmental protection; realizes the utilization of waste; solves the problems of slow forming and low strength of traditional cold mix asphalt mixture, has better road performance and wider application.

Description

technical field [0001] The invention relates to the technical field of asphalt modifiers, in particular to a normal temperature asphalt modifier and an application method. Background technique [0002] my country is now in a period of rapid development. Although science and technology are developing rapidly and people's living conditions are improving, the corresponding environmental pollution is also increasing. In 2019, China's carbon emissions reached 10 billion tons, ranking first in the world. Hot mix asphalt is the main material used in asphalt pavement paving in my country today. It is a material that heats, spreads and rolls asphalt and aggregates under high temperature conditions. Although it has the advantages of excellent performance and low cost, due to the need for high temperature heating, a large amount of benzopyrene, asphalt smoke, CO 2 , NO, SO 2 Such toxic and harmful gases not only directly threaten the health of operators, increase the risk of cancer f...
