Mar 15, 2017 Similarly, it is found that both gradation type and gradation optimizing methods have a greater effect on the high temperature stability of asphalt mixtures . Although the importance of aggregate gradations in mixtures has been valued, the effect of proportion of difference size aggregate on mixture properties is difficult to be evaluated in ...

Effect Of Pretreatment On Crushing Process Of Waste

The crushing products of circuit boards after heating are very different. Therthe e are more nonmetallic flocculent fibers in crushing products in the gradation range of +1.25mm. In the gradation range of 0.074mm-1.25mm, the crushing products appear as granular metallic particles and needle-like or powdery metalloid.

Determination Of Gradation Of Recycled Mixed Coarse

A loading crushing test of recycled mixed coarse aggregates in the same particle diameter range is carried out, and the crushed coarse aggregates are screened, manually sorted, and weighed to study the crushing characteristics of recycled mixed coarse aggregates. The results show that the effect of “reinforcing the strong and discarding the weak” exists between two types of recycled ...
