Isolation performance library-based isolation performance evaluation method of asphalt isolation agent

Abstract

The invention discloses an isolation performance library-based isolation performance evaluation method of an asphalt isolation agent. The isolation performance library-based isolation performance evaluation method comprises the steps of 1, inputting constituent information of an asphalt isolation agent to be tested; 2, inquiring an isolation performance library; 3, evaluating isolation performanceof the asphalt isolation agent to be tested, wherein the step of evaluating the isolation performance of the asphalt isolation agent to be tested comprises four steps of brushing the asphalt isolation agent, testing drawing, determining effective isolation frequency and outputting an isolation performance evaluation result; and 4, updating the isolation performance library. An isolation performance index of the asphalt isolation agent to be tested is given out by inquiring the asphalt isolation performance library to be built in advance, and intuitive and accurate evaluation is performed on the isolation performance of the asphalt isolation agent to be tested according to the isolation performance index; and meanwhile, the isolation performance evaluation method of the asphalt isolation agent is provided and can be used for performing simple and accurate evaluation on the isolation performance index of the asphalt isolation agent which is not stored in the asphalt isolation performance library, the asphalt isolation performance is updated and completed according to an evaluation result, and subsequent all-around and rapid inquiry and application are facilitated.

Description

technical field [0001] The invention belongs to the field of asphalt pavement construction anti-sticking technology, in particular to a method for evaluating the isolation performance of an asphalt release agent based on an isolation performance library. Background technique [0002] Asphalt mixture is a composite material, mainly composed of asphalt, coarse aggregate, fine aggregate, mineral powder, and some polymers and wood cellulose are added; different structures are formed by mixing these materials with different qualities and quantities. And have different mechanical properties. During the construction of asphalt pavement, the excellent adhesion of asphalt makes hot asphalt mixture, especially modified asphalt mixture, also have an adhesion effect on road construction tools and equipment, which not only affects the construction progress of pavement pavement, but also affects The quality of pavement construction can also increase the labor intensity of construction wo...

Problems solved by technology

However, the asphalt release agent isolation performance evaluation test device and method disclosed in the above-mentioned patents have the following problems: First, the isolation performance evaluation process is complicated: it is necessary to pass the tensile force and displacement value, force and displacement curve, interface microscopic photos and can be isolated Second, there are many human interference factors in the test process, and the test results are inaccurate, which leads to unreliable evaluation results of isolation performance: for example, the analysis of microscopic photos of the interface is mainly carried out by humans Analysis, the analysis results are inseparable from the test experience and subjective judgment of the analysts, and at the same time, there is a lack of a simple and reliable analysis method, so an objective and accurate analysis result cannot be obtained; another example is that there are many problems in the statistics of the number of isolations , when the actual test is carried out under what circumstances the teste
