塑胶跑道在我国已有30多年历史,分为全塑型、混合型和颗粒型,主要由面层和基础层构成,厚度一般为13mm。全塑型塑胶跑道的面层由浇注型聚氨酯(RCPU)和防滑胶粒(EPDM或RCPU胶粒)组成,RCPU成本高,因此跑道造价较高;混合型塑胶跑道使用RCPU作主体材料,加入10%～25%废旧轮胎胶粒,上部撒防滑胶粒,造价比全塑型塑胶跑道低;颗粒型塑胶跑道以废轮胎胶粒为主体材料(60%～70%),用RCPU作粘合剂,采用摊铺法施工制成,造价,但施工所用的摊铺机、喷涂胶粒包胶机等铺设设备需要进口,一次性投入很高,且性能较前两种差。目前国内塑胶跑道以混合型为主。以上各类塑胶跑道均需与沥青路面基础良好粘合,基础造价一般80～120元·m-2,塑胶跑道总造价一般230～450元·m-2。虽然塑胶跑道弹性适中,美观实用,能提高运动员比赛成绩和保护运动员免受意外事故伤害,但造价高,至今未普及应用。
塑胶跑道介绍：规格：厚度：13mm、材质：EPDM塑胶颗粒、可选颜色：红、绿为主要颜色。能解决因地基结构和冷缩热胀而产生的问题；透水透气度高；能以EPDM物料设计所需图案及各类标志；富弹性，减轻运动创伤；恒久耐用，抗寒抗冻是它的特点。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天候室外运动场地坪材料。
The plastic runway has a history of more than 30 years in our country. It is divided into plastic, mixed and granular types, consisting mainly of the surface layer and the base layer, and the thickness is generally 13mm.The surface layer of the plastic raceway is composed of pouring polyurethane (RCPU) and anti-skid (EPDM or rccpu). The cost of RCPU is high, so the runway cost is high.The mixed plastic runway USES rccpu as the main material, and 10% ~ 25% of the waste tyre rubber is added, and the upper part of the anti-skid rubber is lower than the plastic runway.Particles type plastic runway by waste tires colloidal particles (60% ~ 70%) as the main material, adhesive for RCPU, the ping b construction, lowest cost, but the construction of per, spraying colloidal particles need to import plastic package machine laying equipment, one-time investment is high, and the perbance of the previous two differentia.At present, the domestic plastic runway is mainly mixed.All kinds of plastic racetracks should be bonded with the asphalt pement foundation, the basic cost is generally 80 ~ 120 yuan ·m-2, the total cost of plastic runway is generally 230 ~ 450 yuan ·m-2.Although the plastic runway is flexible and beautiful, it can improve the perbance of athletes and protect athletes from accidental injuries, but it is expensive and has not been widely used.
Specification: thickness: 13mm, material: EPDM plastic granule, optional color: red, green as the main color.It can solve the problems caused by the foundation structure and shrinkage and heat expansion;High permeability;Design of EPDM materials and all kinds of marks;Rich elasticity to reduce sports injury;Durable and durable, cold and cold resistance is its characteristic.Plastic runway is composed of polyurethane material such as rubber, he certain elasticity and color, he a certain ability to resist ultriolet ray and aging resistance force is internationally recognized as the best all-weather outdoor sports ground floor material.
