Plastic-weather athletics track surface material, the use of polyurethane synthetic rubber track material sales, commonly known as PU (Polyurethane) runway material, in the nineteenth century by scientists polyo1 active hydrogen-containing isocyanate-containing NCO of it with an appropriate extension of the synthesis reaction, in Founded in the 1960s the United States, in 1968, the first time you use the Olympic Games in Mexico nineteenth to rave reviews, since the plastic runway in the world becoming more common. Its main characteristics are: strong bonding strength and flexibility, elasticity and good weather resistance, oil resistance, solvents, acid-alkaline good, simple construction, easy maintenance, due to its superior material properties direct runway, the early twentieth century was IOC recognition surface dressing for the athletics track laid its unrivaled position in the sports arena. Currently, the only score of the game on the ground plastic stadium was only recognized by the IOC and IAAF. With the further development of China's economy, improve people's material level, is certainly greatly improve people's enthusiasm to participate in sports; excellent sports venues, will be the first choice, therefore, new or rebuilt plastic track is bound to become a trend. Process structure: all free renewable rubber polyurethane (Pu) laying plastic layer made of resilient non-slip handle laying decent thickness 9-13mm. With high resilience, and resistance to deformation Sting, long service life. Suitable for professional competitions and training at all levels, teaching plastic runway. Construction Technology: plastic runway paving asphalt or concrete foundation, foundation and road construction practices roughly the same. Whether asphalt or cement foundation, and its surface flatness higher, in order to ensure a time, the elastic plastic layer thickness uniformity, and does not waste rubber. On the basis of quality requirements are as follows. 1, both the use of asphalt or concrete foundation base should have a certain strength and stability. 2, the base can not produce cracks and uneven due to the heat caused by the freeze freeze up. 3, the base should be a certain flatness: 3 m straightedge error of 3 mm, a certain slope: horizontal <1 ‰, high jump area <4 ‰, the surface should be flat, smooth, to ensure drainage. 4, the best use of asphalt base without wax, wax-containing little or bituminous material, which must be fully compacted asphalt mixture. 5, between the flood frozen area, asphalt layer and gravel layer, add a layer of geotextile best buffer layer. Groove along the edge of the gutter should be done on the basis of special water treatment, because these places most prone to frost. 6, the base surface should be kept clean and dry asphalt base after the completion of more than 30 days of maintenance requirements runway proxy materials to make the asphalt surface of the low-boiling component to play to ensure the plastic layer and the foundation has sufficient bond strength. 7, a concrete foundation should be 30 days maintenance period, leaving a large area to be considered suspect telescopic joints, before surfacing layer must also be diluted with 5-6% hydrochloric acid solution, the concrete foundation for processing, and then rinse with water, completely dry before laying the plastic surface.
