为了有效减少路面地表径流，发挥透水性沥青路面的透水功能，明确空隙率、有效空隙率及渗透系数三者之间的关系，以便确定符合地域降雨特点的透水性沥青混合料目标空隙率，依据水量平衡原理和水力学理论，建立了基于有效控制路面地表径流的透水性沥青路面的渗透蓄水简化模型。通过试验分析，明确了透水性沥青混合料的空隙率、有效空隙率及渗透系数有很好的线性相关关系。通过设计降雨量、透水性沥青路面计算面积和路面综合坡度等为计算参数，得到了透水性沥青混合料的目标空隙率计算方法。该方法能够针对不同地区的降雨特点，计算出满足透水功能的透水性沥青混合料的目标空隙率。

In order to decrease the volume of road runoff and provide good water permeability,it is necessa-ry to understand the relations among air void,effective air void and permeability coefficient.Thus,the ob-j ective air void of porous asphalt mixture,according to the local rainfall characteristics,can be determined. A simplified infiltration-water storage model was established,according to the principle of water balance and hydraulics,to decrease the road runoff quantity.Meanwhile,linear relationships among air void,ef-fective air void and permeability coefficient were observed through tests.Thus,a new approach to calculate the obj ective air void of porous asphalt mixture was put forward by using such as design precipitation,the calculated area of porous asphalt pavement and resultant gradient.It shows that the new approach can esti-mate the obj ective air void of porous asphalt mixture for meeting the demand of water infiltration function in different regions based on different rainfall characteristics.
