Abstract

The mixing uniformity of cement stabilized crushed stone includes two aspects, one is the uniformity of cement coating on aggregate, and the other is the uniformity of coarse and fine aggregate distribution. The uneven cement coating aggregate results in the segregation of base strength distribution. The uneven distribution of coarse and fine aggregates leads to the density segregation of the base layer. Optimization of mixing intensity and mixing time can effectively improve mixing uniformity. The strengthening mechanism of vibration mixing and double mixing tank mixing on cement stabilized gravel mixing was compared and analyzed. Relying on the construction site 800 stable gravel mixing equipment, the key technical parameters affecting the mixing effect were analyzed. The results showed that increasing the number of mixing tanks can effectively solve the problem of short mixing time of continuous mixing equipment. The mixing quality could be improved effectively by increasing the effective mixing time to more than 35s with double mixing tanks; Vibration mixing and forced mixing form energy complementary to solve the inefficient zone of mixing. When vibration mixing is adopted, the vibration frequency should be controlled above 35Hz, increasing the mixing intensity can improve the mixing effect; the selection of filling rate should consider mixture quality and production efficiency. The filling rate of mixing tank is controlled at about 70%, which can ensure the uniform binding of cement binder on aggregate surface.
