High-freezing-resistance cement stabilized macadam mixture and preparation method thereof
The invention relates to a high-freezing-resistance cement stabilized macadam mixture and a preparation method thereof, and the high-freezing-resistance cement stabilized macadam mixture comprises the following raw materials in parts by mass except polypropylene fiber: 75 parts of coarse aggregate, 25 parts of fine aggregate, 5 parts of cement, 0.15-0.35 part of expanding agent, 0.1-0.25 part of latex powder, 0.05-0.1 part of water-absorbent resin, 5.89-6.12 parts of water according to the volume ratio of the polypropylene fiber to cement stabilized macadam (formed by mixing the raw materials) of (1-2): 1000. Compared with the prior art, the cement stabilized macadam mixture applicable to the road base in the Tibetan region, provided by the invention, has good anti-freezing performance after 5 times and 10 times of freezing and thawing cycles, the problem that a common cement stabilized macadam base is difficult to meet the anti-freezing performance of a Tibetan region is solved, and the applicable requirement of the road base in the Tibetan region is met.
本发明涉及一种高抗冻性水泥稳定碎石混合料及其制备方法，除聚丙烯纤维外，其余原料按质量份数计：粗集料75份，细集料25份，水泥5份，膨胀剂0.15～0.35份，乳胶粉0.1～0.25份，吸水树脂0.05～0.1份，聚丙烯纤维按与水泥稳定碎石(上述原料混合而成)体积比(1～2):1000，水5.89～6.12份。与现有技术相比，本发明提供的可于西藏地区道路基层适用的水泥稳定碎石混合料经5次、10次冻融循环后具有良好的抗冻性能，解决了普通水泥稳定碎石基层难以满足藏区抗冻性能的问题，满足了藏区道路基层适用的要求。
