塑胶跑道基础层的防裂要求较高，不能因气候、环境条件而造成沥青混凝土出现裂缝，并影响到塑胶面层。沥青混凝土主要是为塑胶层提供一个平整、坚实的垫层，并在沥青混凝土压实后而塑胶层铺筑前，防止雨水下渗到下面结构层，以免日后水气上升积聚在塑胶层与砂粒式沥青混凝土之间，导致塑胶层隆起、剥离。
Plastic runway base layer crack of requirements, not because of the climate, environmental conditions and cause of asphalt concrete cracks, and affect the plastic surface. Plastic layer asphalt concrete is mainly is to provide a flat, firm cushion layer, and plastic layer after compaction of asphalt concrete paving, prevent the rain infiltration to the layer structure, lest rising moisture accumulation in the future between the plastic layer and sand type asphalt concrete, lead to the plastic layer uplift, stripping.

根据塑胶制品的要求及应用的实际情况，将胶粘剂的粘度控制在2.3～2.6Pa?s范围内为宜。塑胶跑道这一粘度的产品可使塑胶制品具有良好的机械性能及弹性。生产实践表明，反应温度控制在80℃时，制得胶粘剂的粘度为2.4Pa?s。塑胶跑道胶粘剂制造过程中，影响胶粘剂质量的因素有反应温度。
According to the requirement of the plastic products and the application of the actual situation of the adhesive viscosity control in 2.3 ~ 2.6 Pa? It is advisable to s scope. Plastic runway the viscosity of the product can make the plastic products with good mechanical properties and elasticity. Production practice shows that control the reaction temperature 80 ℃, the viscosity of the adhesives was 2.4 Pa? S. Plastic runway adhesive manufacturing process, the influencing factors on the quality of the adhesive with reaction temperature.
　　 塑胶跑道温度的高低直接影响产品的质量，进而影响塑胶制品的性能。运动场地施工在高温下合成，粘度明显增加，严重时，可达半固化状态。
Plastic runway temperature directly affects the quality of the products, thus influence the performance of the plastic products. Sports venue construction in high temperature synthesis, apparent viscosity increases, serious when, can reach half curing condition.
