Description

Technical Field

[0001] The utility model relates to the technical field of road milling, in particular to large-texture anti-skid and noise-reducing road milling and molding equipment. Background Art

[0002] In recent years, my country's highway industry has developed rapidly, and the mileage of highways ranks first in the world. As the number of traffic participants continues to rise, the traffic volume has increased dramatically, and the requirements for road quality have continued to increase, especially the anti-skid performance of the functional layer of the road pavement has become more important.

[0003] We know that when driving, the tire interacts with the road surface under load (embedded, rubbed). When the tire friction coefficient is constant, the friction coefficient of the road surface determines the probability of slippage. Therefore, improving the anti-skid performance of the road surface is to reasonably increase the friction coefficient of the road surface, that is, to increase the roughness of the road surface.

[0004] However, asphalt concrete pavement, as the main road surface paving technology, has also developed many new technologies in terms of anti-skid performance after years of development. For example, OGFC pavement, i.e. large-pore open-graded drainage asphalt pavement layer, and SMA pavement, i.e. asphalt mastic crushed stone mixture pavement. However, whether it is the drainage pavement OGFC pavement designed with a broken-graded mixture and large porosity, or the asphalt mastic filled skeleton embedded type dense structure pavement SMA pavement composed of more coarse aggregate, mineral powder and asphalt and a small amount of fine aggregate. All hope to obtain a larger structural depth or a larger micro-texture through open-graded design to increase the road surface roughness value and achieve improved anti-skid performance.

[0005] However, both of the above two are compacted into a flat surface during the forming process. The roughness value of this flat surface is below the flat surface, and both show the structural depth below the plane, that is, negative texture. Although the roughness value of this negative texture is large, its contribution to anti-skid performance will be greatly reduced. The existing equipment can only process large textures manually during road surface processing, which is slow and requires a lot of manpower. Utility Model Content
