When IRI was replaced with standard deviation(σ) of profilometer, another equation of DAF can be expressed with σ and vehicle velocity. With the riding quality evaluation ranking criterion, the dynamic amplification factor of each rank was also achieved for bituminous pavement and cement concrete pavement.

引入IRI与连续平整度仪测定的标准差σ的关系后，得到动荷系数与σ及车速的关系式，最后结合沥青路面和水泥混凝土路面行驶质量评价标准，提出各路面等级的动荷系数。

The results indicate that the conversion rate of VCC R is about 64 % to 69 % ( daf )

结果表明,VCC-R的回收率在64%～69% ( daf ).
