广西国道G322全州至桂林段是广西重要的北出口通道,沿线的湘桂走廊雨量充沛,气候温和,从古灵渠边穿越湘桂走廊,成为北接中原各省,南连西南出海通道的主干线,是桂北重要的经济动脉和旅游公路。全桂路全段116.72km,2004年改造为40 cm水泥稳定碎石基层和5 cm沥青混凝土面层。经多年运营,部分路段出现路面抗滑性能差、车辙、裂缝等病害,为恢复路面面层使用功能,采用现场热再生复拌加铺技术进行修复,在工程应用中取得了较好的效果。
G322 Guangxi Zhuang Autonomous Region to the Guilin section is an important north exit of Guangxi, along the Xianggui corridor rainfall, mild climate, from the ancient gutan drainage through the Xiang Gui corridor, becoming the central provinces of the Central Plains in the north, southwest of the main channel to the southwest Route, is an important economic artery in North Guangxi and tourist roads. Quan Gui Road 116.72km whole paragraph, in 2004 transformed into 40 cm cement stabilized gravel base and 5 cm asphalt concrete surface. After years of operation, some road sections have poor anti-skid performance, rutting, cracks and other diseases. In order to restore the use of pavement surface, the site is repaired by the hot reclaimed compounding and paving technology at site, and good results have been obtained in engineering application.
