Graded coarse aggregate, graded aggregate, stress absorption thin layer and design method of graded coarse aggregate, graded aggregate and stress absorption thin layer
The invention discloses graded coarse aggregate, graded aggregate, a stress absorption thin layer and a design method of the graded coarse aggregate, the graded aggregate and the stress absorption thin layer. The grain size range of the graded coarse aggregate is 2-10 mm, the kurtosis value of grain size normal distribution is 2.61-4.22, and the skewness value is-0.97-0.08. The graded aggregate comprises graded coarse aggregate, fine aggregate and mineral powder. The skeleton type asphalt-rich stress absorption thin layer comprises graded aggregate and asphalt. The normal distribution rightward-deviated graded coarse aggregate has the advantages that the interlocking capacity and the internal friction resistance are realized, the performance is more excellent and stable, and the construction uniformity is better; the skeleton type asphalt-rich stress absorption thin layer has more excellent anti-cracking performance, fatigue performance, high-temperature performance and skeleton stability performance.
本发明公开了一种级配粗集料、级配集料和应力吸收薄层及其设计方法；本发明的级配粗集料的粒径范围为2～10mm，粒径正态分布的峰度值为2.61～4.22，偏度值为‑0.97～0.08。本发明的级配集料包括级配粗集料、细集料和矿粉。本发明的骨架型富沥青的应力吸收薄层包括级配集料和沥青。本发明的正态分布右偏的级配粗集料具有嵌挤能力和内摩阻力，性能更加优良和稳定，施工均匀性更加良好；本发明的骨架型富沥青的应力吸收薄层具备更出色的抗裂性能、疲劳性能、高温性能和骨架稳定性能。
