塔寺岭至新集段大修方案研究

塔寺岭至新集段2003年竣工通车，二级公路标准。经路况调查，该路段病害较严重，路面强度等级大部分为次等，需要大中修。经论证推荐大修方案为：维持原路线的走向与线形指标；路基路面分路段采取不同的大修方案；桥涵、沿线设施进行完善维修，查缺补漏。经计算该方案造价在合理范围内。

Heavy Repair Scheme of Tasiling to Xinji Highway Section

Tasiling to Xinji Highway section has been completed and opened to traffic since 2003, which is the second-class highway. Through investigating, it is found that the diseases of the highway are serious;the pavement strength grade of this section is almost inferior, major and medium repairs are needed. Through the demonstration of the highway conditions, the recommended scheme is maintaining the orientation of the line and alignment index. Different maintenance schemes should be adopted for different sections of the subgrade-pavement. Bridges, culverts and highway facilities are to be repaired and improved. The budget of the scheme is in a reasonable scope through calculation.
