橡胶沥青加工及应用于密级配混合料的设计分析

Analysis and design of rubber asphalt processing and application for dense gradation mixture

探讨了废旧轮胎橡胶沥青对AC-13工程性质的影响,评价了废旧轮胎橡胶沥青应用于维修工程路面的可行性,并对40目橡胶粉与基质沥青高温混炼而成的橡胶沥青混合料的性能进行了研究,研究结果表明:相同设计条件下,橡胶沥青密级配沥青混合料AC-13体积指标与力学性能满足现行规范要求,可应用于维修工程磨耗层。

Explore the waste tire rubber asphalt influence on AC-13 engineering properties, and the evaluation of waste tire rubber asphalt used in road surface repair project feasibility. It studies the rubber-asphalt mixture performance refined by 40 rubber powder and basic asphalt. The resuits showed that： under the same design conditions, the rubber asphalt dense-graded asphalt mixture volume index and mechanical material properties of AC-13 meet the current specification requirements, can be applied to repair engineering wear layer.
