Design method of high-viscosity and high-toughness ultrathin wearing layer mixture based on pavement performance
The invention provides a high-viscosity and high-toughness ultrathin wearing layer mixture design method based on pavement performance, which comprises the following steps: (1) taking mineral aggregates, and determining the grading of the mineral aggregates; (2) taking a high-viscosity tough asphalt cementing material; (3) determining the designed void ratio of the high-viscosity and high-toughness ultrathin wearing layer mixture; 4) according to the total surface area of the mineral aggregate and the designed thickness of the cementing material film, determining the pre-estimated amount of the high-viscosity tough asphalt, and preparing a Marshall test piece and a rut test piece; (5) forming an asphalt-aggregate ratio-performance coordinate graph to obtain the optimal cementing material dosage, and (6) detecting whether the pavement performance of the mixture under the optimal cementing material dosage is qualified or not, if so, judging that the mix proportion is designed, and if not, redesigning. The invention provides a durability design method taking Marshall stability, void ratio and residual stability as design indexes. And technical support can be provided for development and application of a high-performance thin-layer structure.
本发明提供了一种基于路用性能的高黏韧超薄磨耗层混合料设计方法，包括以下步骤：(1)取矿质集料，并确定矿质集料的级配；(2)取高黏韧沥青胶结料；(3)确定高黏韧超薄磨耗层混合料的设计空隙率；4)根据矿质集料的总表面积与设计的胶结料膜的厚度，确定所用高黏韧沥青的预估用量，制成马歇尔试件与车辙试件；(5)形成油石比‑性能坐标图，得到最佳胶结料用量(6)检测最佳胶结料用量下的混合料的路用性能是否合格，若合格，则判定此配合比完成设计，若不合格，重新设计。本发明提出以马歇尔稳定度、空隙率、残留稳定度为设计指标的耐久性设计方法。能为高性能薄层结构的开发应用提供技术支持。
