【摘要】：大空隙透水性瀝青路面路面具有抗滑、降噪、緩解城市熱島效應等優(yōu)點，是一種環(huán)保型的瀝青路面結構。但是，該類路面也存在局限性。其一，由于水可以在路面空隙中自由通過，這就導致了該類路面的瀝青更加容易老化，且易發(fā)生水損害現(xiàn)象；另外，該類路面在施工過程中降溫較快，這就對施工工藝和施工溫度提出了更高的要求；除此之外，該類路面的透水性能易受車輛荷載作用和堵塞物的影響。這些局限性都嚴重地影響了大空隙透水路面的路用性能。 本文對瀝青混合料透水性能進行了研究，通過引入溫度和瀝青粘度參數(shù)，對已有的瀝青混合料的空隙率預估方程進行了修正，得到了以關鍵篩孔通過率、成型溫度和瀝青粘度為參數(shù)的大空隙透水路面的透水性能預估方程；測定了不同空隙率馬歇爾試件的橫向滲透系數(shù)和縱向滲透系數(shù)，并分析了空隙率與其縱橫向滲透系數(shù)的關系。 分析了使用過程中影響路面透水性能的主要因素，以及大空隙透水路面的空隙特性和堵塞特性，對空隙堵塞情況下的OGFC車轍板試件的滲透性能衰減特性進行了研究；通過不同壓實次數(shù)下試件的高度及空隙率變化，研究了荷載作用對路面滲水性能衰減的影響。 對采用不同膠結材料的旋轉壓實試件進行了抗剪實驗，比較不同膠結料以及試驗溫度下試件的抗剪強度，分析了膠結料類型對混合料抗剪強度的影響，并對其對溫度的敏感性進行了分析；采用拌合力矩法對混合料的施工溫度進行確定。最后，，本文通過在最佳實驗溫度下，通過對公稱最大粒徑、設計空隙率和瀝青粘度等因素進行控制后利用旋轉壓實儀成型試件，計算壓實特性參數(shù)，從而分析大空隙透水路面的壓實特性及其影響因素。
[Abstract]:Large void permeable asphalt pavement is a kind of environment-friendly asphalt pavement structure, which has the advantages of anti-skid, noise reduction and alleviating the urban heat island effect. However, this kind of pavement also has the limitation. For one thing, because water can pass freely through the voids of the pavement, the asphalt of this kind of pavement is more easily aged and prone to water damage; in addition, the temperature of the pavement is reduced more quickly during the construction of this kind of pavement. In addition, the permeability of this kind of pavement is easy to be affected by vehicle load and blockage. These limitations have seriously affected the road performance of large void permeable pavement. In this paper, the permeability of asphalt mixture is studied. By introducing temperature and viscosity parameters, the porosity prediction equation of existing asphalt mixture is modified, and the pass rate of critical sieve hole is obtained. The prediction equation of permeability of large voids permeable pavement with the parameters of molding temperature and asphalt viscosity was obtained, and the transverse and longitudinal permeability coefficients of Marshall specimens with different porosity were measured. The relationship between the porosity and the longitudinal and transverse permeability coefficient is analyzed. In this paper, the main factors that affect the permeability of pavement are analyzed, and the characteristics of void and blockage are analyzed. The attenuation characteristics of permeability of OGFC rutting board under the condition of void blockage are studied. The influence of load on the attenuation of seepage performance of pavement is studied by changing the height and void ratio of the specimen under different compaction times. In this paper, the shear strength of rotating compacted specimens with different cementing materials is compared, and the influence of the type of binder on the shear strength of the mixture is analyzed by comparing the shear strength of the specimens with different binders and test temperature. The sensitivity of the mixture to temperature is analyzed, and the mixing moment method is used to determine the construction temperature of the mixture. Finally, under the optimum experimental temperature, the parameters of compaction characteristics are calculated by controlling the nominal maximum particle size, designing porosity and asphalt viscosity, etc. The compaction characteristics and influencing factors of large void permeable pavement are analyzed.
