多年冻土地区道路修筑一直被视为世界性难题,公路路面特殊的使用和施工条件对路面材料与结构提出了特殊要求。本文从路面材料和结构两方面,对多年冻土地区沥青路面设计技术进行系统深入的研究。
     通过模拟试验,研究了低温条件下水泥稳定砂砾的强度、收缩和抗冻等特性,首次提出了养生温度对强度形成影响的临界温度,推荐了收缩最不利状况和抗冻耐久性的适宜评价方法,并提出了混合料配合比设计方法。
     对级配碎石强度构成和变形过程分析认为,其塑性变形的本质是颗粒之间的剪切变形。利用自行研发的柔性材料剪切性能测试仪,分析了级配碎石的抗变形能力,综合CBR和剪切试验分析结果,提出了基于CBR和剪切强度双指标控制的关键筛孔及其通过率合理范围及组成设计方法。
     通过沥青稳定碎石低温特性试验分析,提出了以温度应力比和弯曲应变能为主要指标的混合料低温抗裂性能综合评价方法,以及基于强度和大型马歇尔指标的沥青稳定碎石配合比设计方法。
     通过面层沥青混合料的低温性能试验,分析了不同因素对混合料低温性能的影响,重点研究了热老化对沥青混合料低温抗裂性能的影响,提出了基于低温性能的面层沥青混合料配合比设计方法。
     在冻土路基融沉变形分析的基础上,定量分析了路基不均匀融沉变形对沥青路面结构的影响,首次提出了多年冻土地区沥青路面结构融沉附加应力计算方法。根据多年冻土地区沥青路面的特点,提出了基于荷载与融沉综合作用的多年冻土地区沥青路面结构设计方法,并以交通量、最大融沉深度和土基模量为控制指标,给出了多年冻土地区沥青路面推荐结构。
Road building in permafrost area is regarded as a difficult problem in the world at all times. For many special employing and constructing conditions of the highway pavement in permafrost area, pavement materials and structure should provide many special performances to adapt. In this thesis, the author systemically study on the asphalt pavement design technology of the permafrost area from the material and the structure.
    By the simulating test of the cement-stabilized gravel mixture, the characteristics under the low-temperature condition, such as the strength, shrink and anti-freeze, are studied. The critical dividing temperature that the maintaining temperature influences to the strength forming is firstly confirmed. The shrink worst status and the feasible anti-freeze evaluate method are recommended. Synthesizing the analysis results, the mix design method is put forward.
    On the basis of analyzing the strength forming and the settling process of the graded crushed rock, the author considers the essence of the plastic settlement to be the shear settlement between the grains. The settlements resist capability is systematically analyzed using the flexible material shear performance testing apparatus that invent by the author. According to the CBR and the shear testing results of the graded crushed rock, the key sieve pores and their reasonable passage range are recommended, the mix composing design method based on the CBR and the shear strength is brought forward.
    Through the low-temperature chrematistics testing and analyzing of the asphalt treated macadam, the integrative evaluating method of the low-temperature anti-crack performance that take the temperature stress ratio and the bending strain energy as the primary index. The mix design method based on the strength and the Marshell index for the asphalt treated macadam is developed.
    The effects of varies factors on low-temperature performances of the asphalt mixture are analyzed by the low-temperature performance testing. The influence of the hot-aging to the low-temperature anti-crack performance of the surface asphalt mixture is especially studied. Based on the mixture low-temperature performance, the mix design method is put forward.
    Based on the analysis of the thaw settlement of the frost roadbed, the influence of the roadbed uneven settlement on the asphalt pavement structure is quantitative analyzed, and the calculating method of the additive stress arise from the uneven thaw settlement in pavement structure is firstly given. Aiming at the peculiarity of the asphalt pavement in the permafrost area, the asphalt pavement structure design method found on the integrative effect of the loading and the thaw settlement is brought forward. Taking the traffic, the maximum thaw-settlement depth and the earth modulus as the controlling index, the recommended asphalt pavement structure is presented to the permafrost area.
