从材料角度研究了露石混凝土的设计和制备技术,试验分析了露石剂喷洒时间、用量、表面刷除时间等工艺参数对露石混凝土构造深度的影响,确立了制备工艺的关键参数,并研究了露石处理对路面防滑性、耐磨度、排水能力及力学性能的影响规律。结果表明,露石处理对混凝土的抗压、抗折强度影响甚微,而路面防滑性、排水能力和耐磨度能显著提高。 From the material point of view, the design and preparation technology of the dewstone concrete was studied. The influence of the exposure time, dosage, surface brushing time on the structure depth of the dewstone concrete was analyzed and the key parameters of the preparation process were established. The influence of dew treatment on slip resistance, wear resistance, drainage capacity and mechanical properties of pavement was studied. The results show that the treatment of dewstone has little effect on the compressive strength and flexural strength of concrete, while the slip resistance, drainage capacity and wear resistance of pavement can be significantly improved.
