Laboratory tests were carried out on two aggregate gradings with asphalt content of 7 % , 8 % and 9 % , and with cement content of 2 % , 3 % and 4 % respectively 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 将最紧密堆积原理和流变学原理相结合,运用于免振捣混凝土配合比设计之中,系统地研究了砂率、集料级配、水泥浆量、矿物掺合料等因素对免振捣混凝土物理力学性能、工作性能、耐久性能的影响,成功配制出从c20 - c80及以上强度等级的高性能免振捣混凝土。
Based on the chang - yu highway in julin province , this paper focus on gap - graded asphalt mixtures . aggregate grading of the gap - graded hma was designed by means of void design procedure . this paper give out a kind of new gradation of stone matrix asphalt . at the same time , this paper also studies the effect of aggregate size on road - related performance in some different gradings 本文以吉林省长余高速公路为依托,从沥青混合料的结构形态入手,利用体积法,对骨架密实型级配类型的沥青混合料的级配进行研究,提出新型的沥青马蹄脂级配,并针对不同级配的沥青马蹄脂碎石混合料,全面分析了粗,细集料的粒径变化对其各种路用性能的影响。
The results of research work show that the values of sand rate , aggregate grading , paste content and mineral admixtures control the degree of tightness pile up and the workability of fresh concrete , furthermore , they determined the mechanics performance and the durability of self - compacting concrete 研究表明,砂率、集料级配、水泥浆量、矿物掺合料等因素的取值决定了免振捣混凝土的紧密堆积程度及新拌混凝土的工作性能,从而进一步决定了免振捣混凝土的物理力学性能及耐久性能。
