透水鋪裝技術和應用

詳細說明

普通路面雨水一般通過雨水口或線性排水溝收集匯入雨水管網，而高架橋面的雨水采用高效橋面雨水口收集雨水匯入雨水管網。

OGFC，全稱為: Open Graded Friction Course,是一種嵌擠型熱拌瀝青混合料。

采用開級配抗滑磨耗層( OGFC )瀝青混合料鋪筑的路面能迅速從其內部排走路表雨水，具有防滑、耐磨及降

噪的特點。OGFC瀝青混合料空隙率大于18%，具有較強的結構排水能力，適用于多雨地區修筑瀝青路面的

表層或磨耗層。

級配鋪裝的透水瀝青路面不僅實現強度高、高低溫性能好、平整度密實等路用功能，還能顯著提升城市道路

降噪排水的環保功能。

OGFCFulI name for:Open Graded Friction Course,lt is a kind of embedded hot mix asphalt.The open

graded graded wear resistant (OGFC) asphalt mixture paved pavement can

quickly discharge rainwater from its interior. lt has the characteristics of skid resistance, wearresistan-

ce and noise reduction. OGFC asphalt mixture has a porosity of more than 18%, andlhas a strong str-

uctural drainage capacity. It is suitable for building asphalt pavement surfaceor wearing layer in rainy

areas.

The permeable asphalt pavement with graded paving not only realizes the functions of highstrength,

high and low temperature performance, smoothness and compactness, but alsoremarkably improves

the environmental protection function of noise reduction and drainageof urban roads.
