Based On The Photoelectric Colormetric Method Of Asphalt And Mineral Aggregate Adhesion Effect

During the usage of asphalt pavement, due to the presence of water, greatly reducing theroad usage performance. Now it has become one of the main forms of pavement moisturedamage. Water is an external factor affecting asphalt pavement performance, adhesionbetween asphalt and mineral aggregate is internal factors. Under the combined action of twofactors on the pavement service life and performance are affected. Methods for evaluatingadhesion between asphalt and mineral aggregate lot, this article is mainly based on existingevaluation of adhesion of asphalt and aggregates, trying to find a more scientific and effectivemethods to determine the adhesion between asphalt and aggregate is good or bad.Through the introduction of mineral aggregate and asphalt material properties andadhesion produce basic principle, analyze their impact on the overall asphalt mixture waterstability. Think the chemistry and structure of the mineral aggregate surface texture of asphaltmix is the main factor affecting the stability of the water.Adhesion generated from the perspective of the basic theory to analyze the impact ofvarious types of forces generated when the asphalt and mineral aggregate adhesion effects, aswell as evaluating the adhesion of asphalt and mineral aggregate current commonly usedmethods. Test methods for combining water stability of asphalt mixture analysis, indirectevaluation of asphalt and mineral aggregate adhesion.Analysis of photoelectric Colorimetry fundamentals and methods of test steps, testingthree different modified asphalt and aggregates of adhesion, and in contrast to water boilingtest, validate the feasibility of photoelectric Colorimetry, but also illustrates the superiority ofphotoelectric Colorimetry test.
