摘要:

为保障现代道路使用寿命及行车安全,用高性能修补材料对破损道路进行快速修补是一种高效便捷且低碳环保的手段。本文采用硅酸盐水泥与硫铝酸盐水泥复配成胶凝体系,掺加废弃轮胎橡胶粉(RP)与可分散乳胶粉的同时引入氧化石墨烯制备出纳米材料/聚合物/橡胶三元改性水泥基复合材料(NPRM),用正交优化方法对NPRM各项修补性能综合量化分析。经极差与方差分析优化出NPRM最优配合比,相应最优配合比下NPRM流动扩展度、终凝时间、28 d折压比、28 d弯拉粘结强度、90 d干燥收缩分别为194 mm、115 min、0.319、5.35 MPa、93.57×10-6,相比于传统修补砂浆拥有更优异的综合修补性能。同时RP的掺入可显著减少行车荷载产生的冲击与噪声,在NPRM修补劣化城市道路的同时实现了耗能吸声效能。

Abstract:

To ensure the service life of modern roads and driving safety, fast repairing damaged roads with high-performance repair materials is an efficient and environmentally friendly approach. In this paper, Portland cement and sulfur-aluminate cement were combined to form a compound cementitious system. Recycled tire rubber powder (RP) and dispersible latex powder were added simultaneously, and graphene oxide was further introduced to prepare a nanomaterials/polymer/rubber ternary modified cement-based composites (NPRM). The orthogonal optimization method was used to comprehensively and quantitatively analyze the various repair properties of NPRM. After conducting the analysis of variance, the optimal ratio of NPRM is determined. The flowability, final setting time, 28 d flexible/compressive strength ratio, 28 d flexural tensile bond strength, and 90 d drying shrinkage of NPRM with the optimal ratio are 194 mm, 115 min, 0.319, 5.35 MPa, and 93.57×10-6, whose comprehensive repair performances are superior to those of traditional repair mortar. Moreover, the incorporation of RP can significantly reduce the impact and noise generated by vehicle loads, hereafter achieves energy absorption and sound absorption effect when use NPRM to repair deteriorated urban roads.

Key words: road repair, recycled tire rubber, polymer modified mortar, nano-enhancing, bond strength, shrinkage performance, sound absorption performance
