以透水性路面多孔率沥青混合料颗粒分布为例，见表1.1。空隙率一般在20

Take the particle distribution of porous asphalt mixture for permeable pavement as an example, see Table 1.1. <br>The porosity is generally around 20%, and the target value of the permeability coefficient exceeds 10-2cm/s. For general roads, the Marshall stability target value exceeds 3.43KN. For heavy-duty traffic, the target value of dynamic stability exceeds 3000pass/mm.

For example, the distribution of asphalt mixture particles with permeable road porous rate is shown in Table 1.1.<br>The clearance rate is generally around 20%, and the target value of the permeability coefficient exceeds 10-2cm/s. For the average road, the Marshall Stability Target is above 3.43KN. For heavy-duty traffic, the dynamic stability target value exceeds 3000pass/mm.

Taking porous asphalt mixture particle distribution of permeable pavement as an example, see Table 1.1.<br>The porosity is generally about 20%, and the target value of permeability coefficient is more than 10-2cm / s. For general roads, the target value of Marshall stability is more than 3.43kn. For heavy traffic, the target value of dynamic stability is more than 3000pass / mm.<br>
