A method for evaluating the isolation performance of asphalt release agent based on the isolation performance library

Abstract

The invention discloses a method for evaluating the isolation performance of an asphalt release agent based on an isolation performance library, comprising the steps of: 1. inputting component information of the asphalt release agent to be tested; 2. querying the isolation performance library; 3. isolation performance of the asphalt release agent to be tested Evaluation, including four steps of asphalt release agent brushing, pull-out test, determination of effective isolation times and output of isolation performance evaluation results; 4. Update of isolation performance database. The invention provides the isolation performance index of the asphalt release agent to be tested by querying the pre-established asphalt isolation performance database, and conducts an intuitive and accurate evaluation of the isolation performance of the asphalt release agent to be tested through the isolation performance index, and provides an asphalt release agent isolation The performance evaluation method can easily and accurately evaluate the isolation performance indicators of asphalt isolation agents not stored in the asphalt isolation performance database, and update and improve the asphalt isolation performance database according to the evaluation results, which is convenient for more comprehensive and rapid query and use in the later period.

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 tested asphalt does not have the isolation performance is not clearly and clearly defined, and the state of the tested asphalt does not have the isolation performance is also subjectively judged by the tester, the subject's subjective consciousness, experience, etc. impact, the judgment result is inaccurate, so different testers may come up with different judgment structures, resulting in inaccurate statistics of the number of isolations; third, the operability is poor, and it is impossible to make reasonable and accurate isolation performance tests and evaluation results : Can only provide a plurality of test parameters (such as tension and displacement value size, force and displacement curve, interface microscopic photo, isolation times, etc.) The degree of influence on the isolation performance of the tested asphalt release agent is different, so the above-mentioned multiple test parameters cannot make a judgment on the isolation performance of the asphalt release agent, and it is impossible to obtain an effective evaluation result of the isolation performance
