本文以甘肃省兰?白，馋?柳两条高速公路级配设计任务为依托，从sma混合料的结构特点出发，对沥青玛蹄脂和矿料级配分别进行了研究。 - The curve of mix proportion kept away from the restricted zone in order to provide enough voids in mineral aggregate ( vma ) to fill the high content of conductive materials . conductive powder can regard as a part of filler in asphalt concrete
导电沥青混凝土的级配设计采用superpave设计方法，合成曲线尽可能远离禁区，提供足够的矿料间隙率来填充高掺量的导电相材料。 - 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。 - The latest domestic and foreign achievements on anti - skidding surface of asphalt pavement were collected in this paper , and the major problems on grade design in our country were also thoroughly analyzed . according to systematic analysis on anti - skidding mechanism of asphalt pavement surface , the paper introduced the concept of reference point and forbidden zone of superpave technology to control grade curve " s trends and discussed the influence on pavement surface " s ability of anti - skidding and durability
