portant; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important;">颜色：各区域颜色应基本均匀一致，多色彩设计的跑道应不眩目，不造成相关比赛项目的混乱。

portant; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important;">面层质量：表面材料不脱粒，无裂痕、分层、起鼓现象，面层耐磨层厚度不低于2mm。

portant; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important;">平整度：任何位置3米直尺误差不大于3mm。

portant; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important;">厚 度：跑道区域厚度必须在13mm±2mm以内，合格率90%以上。跑道任何位置不得少于9mm，加厚区（如撑杆跳、标枪、跳远起跑道、跳高加厚区）应大于18mm。辅助区厚度宜在9mm以上。

portant; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important;">排水性：跑道应该自外向内有8‰左右的坡度，能够保证雨后40分钟左右场地基本无积水。
