Increasing production and improving quality of shaft kiln cement ran be done by using high sulfur bituminous coal adding fluorite to form fluo& sulfur composite mineralization and high KH, high Fe proportion, mixing admixture to reduce SO_3 content in cement.

使用高硫烟煤外加萤石，形成氟、硫复合矿化作用，加上高KH、高铁配料，掺入混合材，降低水泥中SO3含量，能提高立窑水泥产质量。

Although the bituminous pavement of cement stable sandy foot layer has good effect in most engineering, it has partial craze of pavement, even with net-shaped crack distortion and structural destruction, which not only shorten the using age of road but also bring hidden trouble for safety.

水泥稳定砂砾基层沥青路面虽然在大部分工程使用中效果不错，但仍有局部路面开裂的问题，甚至发生网裂变形和结构性破坏，从而缩短了道路的使用寿命，也给行车安全带来隐患。

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。

As far as the rebuilding of damaged cement concrete are covering with bituminous layer and using steel fiber concrete.

文章介绍水泥混凝土路面损坏后的改造方法，主要有加铺沥青层和采用钢纤维混凝土修补等。

There is no reasonable consideration of dynamic amplification effects of vehicle loading in the existing design specifications for bituminous pavement and cement concrete pavement in China.

目前我国路面设计规范对车辆荷载的动态影响缺乏合理的考虑。
