1、坡度:横向<1%(弯道8‰、直道5‰、半圆区5‰),纵向<1‰,跳高区<0.4%,表面应平坦光滑、排水畅通。
1, the slope: lateral <1% (curve 8 per thousand, straight 5 per thousand, semi-circular area 5 per thousand), the longitudinal <1%, the high jump area <0.4%, the surface should be flat and smooth, smooth drainage.
2、平整度:平整度合格率在95%以上,3米直尺误差3mm。
2: smoothness, flatness of qualified rate of more than 95%, 3 meter ruler error 3mm.
3、定位: 为准确施工及画线需要,应用牢固鲜明标志物标出跑道场地的四个半圆切线点和两个圆心。
3, the need for accurate positioning: the construction and application of line drawing, solid distinctive signs four semicircles tangent point mark the track and two center.
4、排水:排水系统在大雨后二小时必需排出积水。在冰冻地区,沥青层与碎石层之间最好加一层土工布缓冲层。沿排水沟槽的基础应做特殊防水处理。
4, drainage: drainage system in the rain after two hours required to discharge water. In the frozen area, between the asphalt layer and gravel layer is better to add a layer of geotextile buffer layer. Foundation along the drainage trench should be special waterproof treatment.
5、强度和稳定性:基础应具有一定的强度和稳定性,表面均匀坚实、无裂缝,无烂边,接缝平直光滑。垫层压实,密实度大于95%,在中型碾压机压过后,无显著轮迹、浮土松散、波浪等现象。
5, strength and stability of the foundation: should have a certain strength and stability, uniform solid surface, no crack, no broken edge, flat and smooth joints. Cushion compaction, density is greater than 95%, and in the medium rolling machine pressure after, no significant wheel track, regolith loose, wave phenomenon.
6、保养期:基础表面要保持清洁干燥,沥青基础完工后要求30天以上的保养期,以使沥青表面低沸点成份挥发掉,保证塑胶层与基础有足够的粘接强度。混凝土基础也要有30天保养期,大面积使用需考虑留伸缩缝。在铺面层前需对混凝土基础进行处理。
6, the maintenance period: the surface of the base should be kept clean and dry, asphalt base after the completion of requirements for more than 30 days of the maintenance period, in order to make asphalt surface low boiling point components volatilize, ensure the plastic layer and the base bond strength enough. Concrete foundation also to have 30 days of the maintenance period, the use of large area need to consider the expansion joint. On the pavement before processing the concrete foundation.
