The results show that, using the cement as a filler, there are no impacts on the high temperature performance, neither do the marshell stability and the split strength; nor the residual stability and the TRS are highly improved, even exceed the original mixture, which explains that using the cement as a filler also is used for the asphalt mixture with PR.

试验结果表明，采用水泥替代矿粉作为填料后，对掺加PR.S添加剂沥青混合料的高温性能几乎没有影响，其稳定度和劈裂强度也没有明显提高；而其残留稳定度和劈裂强度比却得到了很大的提高，甚至已经超过了未掺加PR.S添加剂时沥青混合料的对应数值。

S additive added as for the common mixture. Meanwhile, the complex modified asphalt mixture using the cement as a filler and with the PR.

这说明采用水泥替代矿粉以提高普通沥青混合料水稳定性能的方法，同样适合于掺加PR.S添加剂沥青混合料的情况。

Mechanized construction of high-grade highway road status, asphalt concrete, cement concrete, RCC, as well as supporting the existence of grass-roots construction machinery and accessories in the focus of questions should consider the issue of the roller compacted asphalt concrete machinery importance; cement concrete slipform paver machine as the leading equipment machines for concrete mixing equipment related to measurement and mixing homogeneity of the importance of indicators; of RCC and grass-roots construction machinery, mixing equipment is still emphasize the measurement accuracy and mixing uniformity; on the grass-roots level paver problem, development and the condition of our country to adapt the automatic leveling of the ground plane; stone processing counterattack crusher used to solve the problem of the ratio of the needle plate.
