摘要
从理论与实践两方面提出了密级配沥青砼合理级配的标准。分析级配变化与各项指标的关系,对影响混合料性能的因素作了探讨。在分析论证的基础上,提出了沥青砼合理级配的设计原则。
From the theory and practice, the paper proposed the standard of reasonal gradation for close-graded bituminous concrete, analyzed the relations between gradation change and indexes, discussed the factors of influencing mixture performance etc.
