摘要:
为增强机场沥青道面的抗轮辙性能,提出了一种基于新型环氧沥青混凝土的高性能机场道面结构.将新型环氧沥青混凝土EAC20作为机场道面的中面层,SMA13型沥青混凝土作为上面层,AC20型沥青混凝土作为下面层,由此构成SEA机场道面结构.分析了新一代大型客机A380荷载作用下SEA机场道面结构的力学响应,针对机场道面各层沥青混凝土进行永久变形试验,并采用多元线性回归得到各层材料的蠕变参数,以模拟SEA机场道面结构的永久变形.研究结果表明,将新型环氧沥青混凝土作为中面层应用于机场道面,可以减小机场道面结构的应变,沥青面层底部最大拉应变和最大压应变分别约为传统机场沥青道面结构的68%和72%.在1×105次荷载作用下,SEA机场道面结构的永久变形仅为6 mm,约为传统SAA机场沥青道面结构的42.9%.
Abstract:
To improve the anti-rutting performance of airfield pavement, a high performance airfield pavement based on a new type of epoxy asphalt concrete was proposed. With the new type of epoxy asphalt concrete EAC20 as the middle surface course, SMA13 asphalt concrete as the first surface course, and AC20 asphalt concrete as the base surface course, the SEA airfield pavement was built up. The mechanical responses of the SEA airfield pavement under the static loads of the aircraft A380 were analyzed. The permanent deformation tests of the asphalt concrete in different airfield pavement layers were carried out. The creep parameters of the asphalt concrete in each layer were obtained by using the multiple linear regression method to simulate the permanent deformation of the SEA airfield pavement. The results demonstrate that taking the new type of epoxy asphalt concrete as the middle surface course can reduce the strain of the airfield pavement. The maximum tensile strain and the maximum compressive strain on the bottom of the asphalt surface course are respectively about 68% and 72% those of the traditional airfield pavement. Under 1×105 loads, the permanent deformation of the SEA airfield pavement is only 6 mm, which is about 42.9% that of the traditional SAA airfield pavement.
