摘要:
为研究冻融作用对多孔沥青混凝土(PAC)结构、性能和使用寿命的影响,并推荐适用于寒区的PAC级配类型和最佳空隙率,采用X射线计算机断层扫描(CT)和数字图像处理(DIP)技术,提取了PAC三维空隙网络并量化了其结构参数,通过低温劈裂试验、单轴压缩试验和间接拉伸疲劳试验研究了PAC的空隙结构参数、低温劈裂强度、单轴抗压强度和疲劳寿命在冻融作用下的演变规律,并根据空隙结构及混凝土性能的演变建立了基于多标准决策分析理论的寒区PAC配合比优选方法。研究结果表明:在0～12次冻融循环过程中,PAC内部空隙率主要受空隙间连通扩展的影响而迅速增加,12次冻融循环后,小空隙的进一步产生成为空隙率增长的主要机制,由此划分冻融循环作用0～12次为冻融循环前期,13～20次为冻融循环后期; 冻融循环过程中,10 mm2以上的空隙占比在冻融前期逐渐增大,后期缓慢下降,而10 mm2以下空隙占比变化规律则相反; PAC的低温劈裂强度、单轴抗压强度和疲劳寿命的衰减与公称最大粒径和空隙率密切相关,未冻融条件下空隙率对其低温劈裂强度的影响更明显,而冻融条件下公称最大粒径对其低温劈裂强度、单轴抗压强度和疲劳寿命的影响更显著,公称最大粒径较小且空隙率在21%～22%的PAC-13b级配的抗冻融破坏性能最佳。
Abstract:
To investigate the effects of freeze-thaw action on the structure, performance and service life of porous asphalt concrete(PAC), and to recommend suitable gradation types and optimal void contents of PAC in cold regions, the X-ray computed tomography(CT)and digital image processing(DIP)technology were employed to extract the three-dimensional void network of PAC and quantify its structural parameters. Low-temperature splitting tests, uniaxial compression tests, and indirect tensile fatigue tests were conducted to study the evolution laws of void structure parameters, low-temperature splitting strength, uniaxial compressive strength, and fatigue life of PAC under freeze-thaw action. Based on the evolutions of void structure and concrete performance, a mix proportion optimization method based on multi-criteria decision analysis theory was established for PAC in cold regions. The research results reveal that during the process of 0-12 freeze-thaw cycles, the internal void content of PAC increases rapidly, mainly due to the interconnected expansion among voids. After 12 freeze-thaw cycles, the further generation of small voids becomes the primary mechanism for the increase in the void content. Therefore, the freeze-thaw cycle is divided into early stage as 0-12 freeze-thaw cycle action and later stage as 13-20 freeze-thaw cycle action. During the freeze-thaw cycle process, the voids larger than 10 mm2 gradually increase in proportion at the early stage and then slowly decrease at the later stage, whereas the voids smaller than 10 mm2 exhibit the opposite trend. The attenuations in the low-temperature splitting strength, uniaxial compressive strength and fatigue life of PAC are closely related to the nominal maximum aggregate size and void content. Under non-freeze-thaw condition, void content has a more pronounced effect on the low-temperature splitting strength, while under freeze-thaw condition, the nominal maximum aggregate size has more significant impact on the low-temperature splitting strength, uniaxial compressive strength and fatigue life. The PAC-13b gradation characterized by a smaller nominal maximum aggregate size and a void content within 21%-22% exhibits the best performance against freeze-thaw damage.5 tabs, 10 figs, 30 refs.
