Plastic runways have increasingly appeared in various urban sports venues and various public fields, becoming an important choice for people's sports and life. The plastic runways produced by our company are constructed on the basis of asphalt or cement. The basic practices and roads Construction is about the same. The surface flatness of the foundation is required to be high, so that the thickness of the plastic surface layer can be ensured to the maximum extent, and the elasticity is uniform. The quality requirements of the foundation are as follows. 1. Positioning: For accurate construction and line drawing needs, use firm and distinctive markers to mark the four semicircular tangent points and two center points of the runway site. 2. Flatness: The pass rate of flatness is above 95%, and the error of 3m ruler is 3mm. 3. Slope: horizontal <1% (bending 8 ‰, straight 5 ‰, semicircular area 5 ‰), longitudinal <1 ‰, high jump area <0.4%, the surface should be flat and smooth, and the drainage should be smooth. 4. Drainage: The drainage system must drain accumulated water two hours after heavy rain. In frozen areas, it is better to add a geotextile buffer layer between the asphalt layer and the gravel layer. The foundation along the drainage trench should be specially waterproofed. 5. Strength and stability: The foundation should have a certain strength and stability, the surface is uniform and solid, without cracks, no rotten edges, and the joints are straight and smooth. The cushion is compacted and the density is greater than 95%. After the medium-sized roller compactor is pressed, there are no obvious wheel tracks, loose soil and waves in the construction of the plastic runway.
