本论文以沥青混合料AC-20为基础配合比,通过改变硅藻土和岩沥青的不同掺量,研究硅藻土和岩沥青在对沥青混合料的改性效果,并通过室内试验研究确定出硅藻土:岩沥青=5:5时动稳定度可以达到试验要求目标4000次以上,同时将普通沥青混合料、复改硅藻土、SBS改性沥青、抗车辙剂等混合料进行路用性能比对,得出复改硅藻土在水稳定性、动稳定度等方面具有明显的优势,为后续的复改硅藻土应用提供了一定的参考价值。
In this paper, asphalt mixture AC-20 based on the ratio, by changing the diatomite and rock asphalt in different dosages, diatomite and rock asphalt in the asphalt mixture modification effect, and through laboratory tests to determine The diatomite: rock asphalt = 5: 5 dynamic stability can reach the test requirements of the target more than 4,000 times, while the ordinary asphalt mixture, rework diatomite, SBS modified asphalt, anti-rutting agents and other mixture road Compared with the performance, it is concluded that the diatomite rehydration has obvious advantages in water stability, dynamic stability and so on, which provides certain reference value for the subsequent application of reworked diatomite.
