塑胶跑道又称全天候田径运动跑道,由聚氨酯预聚体、混合聚醚、废轮胎橡胶、EPDM橡胶粒或PU颗粒、颜料、助剂、填料组成。塑胶跑道具有平整度好、抗压强度高、硬度弹性适当、物理性能稳定的特性,有利于运动员速度和技术的发挥,有效地提高运动成绩,降低摔伤率。塑胶跑道是由聚氨酯橡胶等材料组成的,具有一定的弹性和色彩,具有一定的抗紫外线能力和耐老化力是国际上公认的最佳全天候室外运动场地坪材料。
Plastic runway is also called all-weather athletics track, the polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particle or PU particles, pigments, additives, fillers. Plastic runway with the formation characteristics of good, high compressive strength, hardness, elastic proper physical stability, conducive to athletes speed and skill to play, effectively improve athletic performance, reduce fall rate. Plastic runway is composed of polyurethane rubber and other materials, has a certain flexibility and color, has a certain anti ultraviolet and aging resistance force is internationally recognized as the best all-weather outdoor sports ground floor materials.
塑胶跑道基层分为水泥混凝土基础及沥青混凝土基础,平整度为3米内,高低差不大于3毫米,塑胶跑道 复合型塑胶跑道 混合型塑胶跑道平整合格率大于90%,倾斜度为3‰-8‰,其他技术要求请参考二级公路混凝土路面施工的技术要求。水泥砼基础,强度高,施工简单,但需要处理好防水和伸缩缝。沥青砼基础,收缩性小、抗裂、防水性能优良,改性沥青软化点高,不易出现反油现象。
Plastic runway base is divided into basic and asphalt cement concrete concrete foundation, flatness is 3 meters, the height difference of less than 3 mm, plastic runway compound plastic runway mixed type plastic runway level pass rate of greater than 90%, the inclination of 3 ‰ -8 ‰, other technical requirements please refer to construction of two level highway concrete pavement technology requirements. Concrete foundation, cement high strength, simple construction, but need a good waterproof and expansion joint. The concrete base asphalt, small shrinkage, crack resistance, excellent waterproof performance, modified asphalt high softening point, anti oil phenomenon does not easily occur.
塑胶跑道面层材料主要为聚氨酯(PU)塑胶及三元乙丙(EPDM)橡胶,其优点具有:弹性优良,接着力强、耐磨、耐酸碱、搞老化,全天候性、环保、阻燃、防尘、无菌、无接缝,清洁、养护简单,颜色鲜艳、有利于美化环境及提高沉重参与运动的兴趣。
Plastic runway surface layer is the main material of polyurethane (PU) plastic and three yuan (EPDM) rubber, its advantages are: good elasticity, strong adhesive force, abrasion resistance, acid and alkali resistance, anti - aging, all-weather, environmental protection, flame retardant, dustproof, sterile, no seams, cleaning, maintenance is simple, bright color, to beautify the environment and improve the heavy participation in sport.
