The Analysis of the Adhesion between Limestone, Basalt and Asphalt

Abstract:

Abstract: During material performance test, it can be seen that the results of 3min water-boiling adhesion experiments of limestone and basalt, in accordance with testing regulations [1], are both fifth grade, without any difference. Through the analysis of microstructure and chemical composition of limestone and basalt, it is found that huge difference exists between limestone and basalt, hence it can be conjectured that their adhesion should be different from that of asphalt. In order to further validate the difference degree of this feature of limestone and basalt, the paper, based on testing regulations, prolongs boiling time in experiment and conducts freezing-thawing cycle for the acceleration of exfoliation of asphalt membrane, aiming to conclude the result that the adhesion between limestone and asphalt is better than that between basalt and asphalt. In this way, solid basis is provided for limestone to replace basalt on the construction of SMA road surface.
