According to this, the paper puts forward a kind of new permeablebase material, which is called porous concrete.
对此，本文研究一种新型的多孔混凝土排水基层材料。

As a part of pavement structure, the mechanical behavior of asphalt treated permeablebase (ATPB) affects the performance of roadway directly.
沥青稳定碎石排水层作为路面结构的一部分，其力学性能直接影响整个路面的使用性能。

In addition, the metal film is directly plated on the air permeablebase cloth to save an airtight thin film, thereby having fine air permeable and moisture permeable properties.
