What are construction requirements for foundation of rubber track surface

The pass rate of flatness is above 95%, and the error of the 3 meter ruler is 3mm, or the height of the part of the water after testing the water does not exceed the height of a dollar coin.

Horizontal <1%, vertical <1‰, high jump area <4‰, the surface should be flat and smooth to ensure drainage.

It is best to use asphalt materials that do not contain wax or contain very little wax, and the asphalt mixture must be fully compacted. The surface is uniform and solid, smooth without cracks, no rotten edges, no pitted surface, smooth and smooth joints. The oil content of the fine asphalt concrete surface is 5.8-6.4%, and the oil content of the rough asphalt concrete is 4.6-5.8%. The compaction density shall not be less than 95%. After the medium-sized roller is pressed, there will be no obvious wheel marks, no soft skin, no loose soil, waves and other phenomena.
