Abstract

The invention relates to an asphalt pavement roller isolating agent as well as a preparation method and a test method thereof. The asphalt pavement roller isolating agent comprises the following components in percentage by weight: 32.2-48.2% of an asphalt anti-aging agent, 33-60% of water, 0.5-3.0% of an emulsifier, 0.3-0.8% of an antioxidant and 5-15% of glycerin. The preparation method of the asphalt pavement roller isolating agent is used for preparing the asphalt pavement roller isolating agent, and comprises the following steps: S1, heating water, and mixing with the emulsifier, the antioxidant and glycerin according to a ratio so as to obtain emulsified liquid A for later use; S2, heating the asphalt anti-aging agent, conveying the emulsified liquid A and the heated asphalt anti-aging agent into a colloid mill emulsifying machine, fully shearing and blending until clustering is avoided or no flocculent mass exists so as to obtain a blend B; S3, pouring out the blend B, and cooling to obtain the asphalt pavement roller isolating agent, and storing or filling the prepared asphalt pavement roller isolating agent. The invention further provides a test method of the asphalt pavement roller isolating agent.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to an asphalt road roller release agent, a preparation method and a testing method thereof. Background technique [0002] With the progress of the times, my country's highway development has made leaps and bounds, and the asphalt pavement has also made great progress and breakthroughs. It accounts for more than 85% of the domestic road pavement, so the research and development of asphalt is getting more and more Important, the research and development of derivative products related to asphalt has also become more and more important, including the research and development of modified asphalt, the research and development of modified asphalt additives, etc. [0003] When the current road roller works on the asphalt pavement that has just been laid, the asphalt will stick to the double steel wheels, which will affect the rolling effect of the asphalt pavement, resulting in dama...
