portant; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important;">顏色：各區(qū)域顏色應基本均勻一致，多色彩設計的跑道應不眩目，不造成相關比賽項目的混亂。

portant; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important;">面層質(zhì)量：表面材料不脫粒，無裂痕、分層、起鼓現(xiàn)象，面層耐磨層厚度不低于2mm。

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

portant; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important;">厚 度：跑道區(qū)域厚度必須在13mm±2mm以內(nèi)，合格率90%以上。跑道任何位置不得少于9mm，加厚區(qū)（如撐桿跳、標槍、跳遠起跑道、跳高加厚區(qū)）應大于18mm。輔助區(qū)厚度宜在9mm以上。

portant; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important;">排水性：跑道應該自外向內(nèi)有8‰左右的坡度，能夠保證雨后40分鐘左右場地基本無積水。
