通过对埃塞俄比亚阿杜瓦到阿迪格拉特公路工程中困难路段全厚式沥青路面的施工实践总结,分析和介绍特立尼达湖改性沥青混凝土配合比的设计方法和使用情况,根据试验结果、铺筑效果以及在实地调查中的对比和研究,得出以特立尼达湖沥青混凝土为面层的全厚式路面结构在长大坡度路段的抗热变形能力较为理想,在改善路面特别是在长大坡度路段的路面质量方面具有显著的的应用优势和广阔的发展前景,以此为相关行业及从业者提供一定角度的参考借鉴。
Through the construction practice of full-thickness asphalt pavement in the difficult section of Adhwa-Adigrat highway project in Ethiopia, the design method and usage of Trinidad modified asphalt concrete mixture are analyzed and introduced. According to the test results, Paving effect and the comparison and study in the field survey, it is concluded that the full-thickness pavement structure with Trinidad Lake asphalt concrete as the surface layer has better heat-resistant deformation ability in the long and large slope sections, It has significant application advantages and broad development prospects in the aspect of pavement quality of the growing grade road sections and provides reference for relevant industries and practitioners from a certain point of view.
