摘要
从1989年京石高速公路半幅48km建成通车,到2003年底,河北省高速公路总里程达1681km,其中98%以上为沥青混凝土路面。经过大体三个阶段的实践探索,河北省高速公路沥青路面技术不断完善,路面的结构耐久性和行车舒适性都有了很大的提高。但是,在高速公路沥青路面中仍旧存在行车道车辙,路面开裂等早期破损等技术问题需要解决。从河北省高速公路路面工程的实践经验出发,结合省外路面技术的最新发展,对进一步提高全省高速公路沥青路面技术提出了初步的建议。
Since the JING-SHI freeway,48km,was open to traffic,there has been 1681 km freeways in Hehei Province in 2003,98% of which are asphalt pavement.By three phases practice and research,the asphalt pavement technology are being improved,and the asphalt pavement durability and running comfortness ability are greatly improved,but three are many problems such as rutting and pavement crack that need to be solved.Based on the pavement practice experience in Hebei Province and up to date development of pavement Technology,many suggestions are made in this paper in order to improve the Freeway Asphalt Pavement Technology.
