technical field

Background technique

The water-stabilized layer is the abbreviation of the cement-stabilized crushed stone layer, that is, the cement-stabilized grading crushed stone is used to complete the compaction and maintenance. The water-stable mix ratio should be tested in the laboratory in advance to determine the cement content and the ratio of coarse and fine aggregates, and at the same time determine the maximum dry density. Large quantities can be mixed with a water-stabilized mixing station. The water stabilized layer is made of graded crushed stone as aggregate, and a certain amount of cementitious material and sufficient mortar volume are used to fill the gap of the aggregate, and it is paved and compacted according to the principle of embedding. The degree of compaction is close to the degree of compaction, and the strength mainly depends on the principle of interlocking and locking between the crushed stones, and there is enough mortar volume to fill the voids of the aggregate. Therefore, in the production of the water stable layer, it is necessary to ensure that the multi-ingredient mixed aggregates are evenly stirred, thereby improving the quality of the water stable layer.

The poor uniformity of water stabilization layer stirring is a long-standing problem in the industry. The stirring operation mode of the traditional continuous mixer is divided into circumferential motion, axial motion and radial motion. The above three mixing methods all use the stirring shaft to stir the mixture in the mixing container, but it cannot make the "binder aggregate" fully dispersed, and it is difficult to mix the sand aggregate and cement and other additives evenly, and because the raw materials are dense , resulting in a slow stirring rate, which in turn affects the construction efficiency.
