Method for testing interaction capacity of asphaltum and aggregate

InactiveCN101162193AAdequate responseInteraction capability reflectsFlow propertiesMaterial testing goodsGramAsphalt mastic
The invention provides a method for detecting the interaction capability between asphalt and aggregate and relates to a detection method. The objective of the invention is to solve the problems that the evaluation criterion of the prior interaction capability between asphalt and aggregate can not be quantified, the test conditions are difficult to be controlled precisely, the repeatability of test data is poor and the interaction capability between asphalt and aggregate can not be demonstrated directly. In the invention, asphalt and dusty kernel are mixed evenly at the proportion of weight from one to zero point eight to one to one point two to generate asphalt mastic; the evenly mixed asphalt mastic of zero point eight to one point two grams is arranged on a lower flat board of a flat board fixture with the diameter of twenty five millimeters and is preserved in the mixed liquor of water and glycol of twenty DEG C to thirty DEG C for fifteen minutes to twenty five minutes; the test time is one hundred to one hundred and forty seconds. The data obtained from the invention is more quantified and the impact by the artificial factors are greatly reduced; the repeatability of the test data is good; the test is performed in a scenario of an simulated road environment and with traffic loads, which is more close to the real road traffic conditions, and the physical meaning of the evaluation criterion is more specified and the interaction capability between asphalt and aggregate can be reflected.
