摘要通过室内试验测试了两种集料级配下，乳化沥青用量分别为7 % 、 8 % 、 9 % ，水泥用量分别为2 % 、 3 % 、 4 %时水泥乳化沥青混凝土的物理、力学性质。 - The grade composite , road performance and its mechanism are systemically studied . 1 ) the aggregate grade of ogfc is studied through the volume method base on the analysis of the aggregate grades . then the grade is verified and the relation between the grade and pore rate is studied statistically , the typical grades of ogfc are developed ; 2 ) the reasonable pore rate of ogfc is studied on the basis of the balance of mechanics and function performance ; 3 ) the mineral fiber is added to the ogfc mixes to increase asphalt content , thus the anti - water performance of ogfc mixes are improved ; 4 ) high viscous asphalt fit for the preparation of ogfc is prepared through composite modification by sbs and rubber powder ; 5 ) the mechanics mechanism of ogfc is studied in the paper , it shows : asphalt paste , as well as the coarse aggregate skeleton , is essential to the mechanics of ogfc
在分析各国ogfc级配的基础上，运用矿料体积法进行ogfc级配设计，用正交实验对矿料级配进行了优化设计，运用数理统计方法分析矿料级配和孔隙率之间的关系，并回归出矿料关键筛孔通过率与ogfc骨架空隙结构关系的数学方程，进而提出了ogfc的合理级配；通过对不同孔隙率典型级配混合料的性能研究，综合力学和功能性能，得出了ogfc的合理孔隙率范围：针对高速公路面层对ogfc力学性能方面的要求，本文从沥青胶结材料、纤维稳定剂两方面对ogfc的性能进行改善：通过sbs和橡胶粉复合改性的方法开发出了适合ogfc的高粘度改性沥青，掺加聚合物纤维，提高ogfc的最佳沥青用量，进而改善了混合料的高温性能和抗水损害性能，优化设计出能满足高速公路路用性能，车辙动稳定度达5000次/ mm以上，动融劈裂强度比90 ，透水系数31ml / s ，并具有防滑降噪功能的开级配沥青磨耗层( ogfc )混合料。 - Moreover , the main components of h mineral admixture is procured from industry waste , and its " production procedure is simple , so its " production cost is very low . the most tightness pile up theory and rheology is successfully applied in the designation of self - compacting concrete , and the factors such as sand rate , aggregate grading , paste content and mineral admixtures are been studied . under the guidance of mix design theory and on the basis of mass experiments , c20 - c80 high performance self - compacting concrete is been produced
