大孔隙水泥穩定碎石排水基層和瀝青面層的有效聯結、混合料本身良好的抗沖刷性能和良好的排水性能，有利於瀝青下面層和排水基層的層間接觸條件維持在連續狀態。 -
The pavement subdrainage system removes excessive subsurface water to the edge of highway in time, so it can improve pavement performance and extend service life. asphalt treated permeable base ( atpb ) material has been widely used due to its high drainability and construction convenience
如果在路面內部設置排水系統，將路面結構中的內部滯水及時排除到路面和路基結構外，可以改善路面的使用性能，提高其使用壽命。 -
By structural analysis and calculation for original highway structure without permeable layer, the critical modulus of base have been obtained which makes asphalt pavement fill different allowable stress criterion. by structural analysis and calculation for different highway structure with permeable layer, critical modulus of permeable base course are obtained to make asphalt pavement fill different allowable stress criterion. the paper also presents the tendency of structure response of different highway structure with drainable layers mainly depends on the thickness of asphalt pavement, the thickness and the critical modulus of permeable base
對于不設排水層的原路面結構，通過結構計算得出對應于不同的瀝青面層容許應力值時所需的基層臨界模量值；對于加設排水層的路面結構，通過結構計算得出對應于不同的瀝青面層容許應力值時所需的排水基層臨界模量值；加設排水層的路面結構的結構反應的變化趨勢主要取決于瀝青面層厚度、排水基層厚度和排水基層臨界模量值。 -
This paper analyses the problem of concrete cracking and leakage, and set up the model of the middle or low - strength steel slag anti - cracking and impermeable concrete ( acic ) on the base of the analysis. the four principles of water permeable resistance character, volume stability character, toughness and anti - chemical corroded character have been put forward for raw materials selection and durability design of acic, acic is designed by the theory of composite material and the theory of fiber - reinforced, and two series of acic, such as fly ash series and steel slag series, have been manufactured by means of mineral admixture, hybrid fiber and chemical admixture. hydrating heat, macro - mechanics quality, durability and microstructure of the acic have been researched
