Substitution material in use for testing construction machinery for asphalt pavement, and its prodn. tech

Replacement one kind of mechanical test pavement construction materials for the production process, the process is aggregate ores: the same standard and the distribution of the asphalt material grade aggregate gradation of ore; temperature conditions using a predetermined phase compared to a corresponding reference standard viscosity values ​​of the same pitch or not less than 5% of the value of machinery lubricants; Whetstone by mass ratio of 2.5% to 3.5% the above lubricating oil and mineral aggregate mixed, lubricant oil mixture ; at 15 ℃ ~ 35 ℃, the quasi lubricant mix slump test, and by adjusting the ratio of the oil, so that the slump value reaches the target value of the actual slump asphalt mixture, namely the said substitute material. Replacement material of the present invention at room temperature flowability realistic simulation of hot asphalt mixture, and can be reused, without consideration of the temperature control problem is not confined to the test site; no "stuck" phenomenon, less slag loss, test environmental pollution; and low cost, easy to clean.
