Gradation design method of ultra-thin overlay asphalt mixture with dense framework
The invention discloses a gradation design method of an ultrathin overlay asphalt mixture with a dense skeleton. The skeleton dense type ultrathin overlay asphalt mixture is prepared from 93 to 95 parts by mass of aggregate, 5.5 to 5.8 parts by mass of rubber modified asphalt and 5 to 7 parts by mass of filler, the filler is mineral powder; the aggregate is basalt, the composition of the aggregate adopts dense gradation, and the maximum nominal particle size is 4.75 mm; the thickness of the cover face ranges from 0.8 cm to 1.5 cm. The skeleton compact type ultra-thin overlay asphalt mixture prepared by the invention has the characteristics of excellent high-temperature rutting resistance and low-temperature cracking resistance, high water damage resistance, long service life and the like; compared with the original pavement, the noise of the paved ultra-thin asphalt pavement is reduced by 2-3 decibels; the mixture can be widely applied to rapid maintenance engineering of asphalt pavements and bridge floors, the service life of the pavements can be prolonged, the overall functions of the pavements are enhanced, and the driving comfort is improved.
本发明公开了一种骨架密实超薄罩面沥青混合料级配设计方法。所述的骨架密实型超薄罩面沥青混合料由93‑95质量份集料、5.5‑5.8质量份橡胶改性沥青、5‑7质量份填料组成；所述填料为矿粉；所述集料为玄武岩，集料组成采用密级配，最大公称粒径4.75mm；所述罩面厚度为0.8‑1.5cm。本发明制备的骨架密实型超薄罩面沥青混合料具有高温抗车辙性、低温抗开裂性优异、抗水损害性能高、使用寿命长等特点，铺筑成的超薄沥青路面同时较原路面噪音降低2‑3分贝；该混合料可广泛应用于沥青路面、桥面快速养护工程中，可延长路面使用寿命，增强路面整体功能和提高行车舒适性。
