摘要

目的在印度农村地区修建了大量道路,将居民区与最近的主要道路连接起来。随着时间的推移,这些道路的路面已经恶化,需要进行某种维护,尽管它们不需要同时进行维护,因为它们都没有恶化到相同的水平。因此,它们必须优先进行维护。设计/方法/方法为了提供一种科学的方法来确定路面维护的优先级,通过专家调查确定了影响优先级的因素及其相对重要性。运用层次分析法(AHP),根据各因素相对于其他因素的相对重要性,科学地确定各因素的权重(重要性)。通过对印度喜马偕尔邦203条低交通量农村道路的案例研究,验证了所提出的方法。最终结果是按照优先维护顺序对这些道路进行排名。结果表明,路面破损、交通量、连接类型和道路沿线的社会经济设施是确定道路维修优先级时需要考虑的四个主要因素。研究局限性/含义该方法提供了一种全面、科学和对社会负责的路面维护优先级方法,该方法将在没有任何偏见的情况下自动选择道路进行维护。实际意义及时维护道路也将节省恢复/重建的预算支出,从而延长道路使用寿命。政府不仅会节省开支,而且会及时为有需要的人提供福利。社会影响公路运输是农村内陆运输的主要方式。及时维护路面将对农村地区的社会经济发展有很大帮助。独创性/价值所提出的方法特别强调长度小但数量多的农村道路。科学的养护道路选择方法将有助于公共工程部门更好地管理农村公路网,而不是随机选择。

Scientific approach using AHP to prioritize low volume rural roads for pavement maintenance
PurposeA large number of roads have been constructed in the rural areas of India to connect habitations with the nearest major roads. With time, the pavements of these roads have deteriorated and they need some kind of maintenance, although they all do not need maintenance at the same time, as they have all not deteriorated to the same level. Hence, they have to be prioritized for maintenance.Design/methodology/approachIn order to present a scientific methodology for prioritizing pavement maintenance, the factors affecting prioritization and the relative importance of each were identified through an expert survey. Analytic Hierarchy Process (AHP) was used to scientifically establish weight (importance) of each factor based on its relative importance over other factors. The proposed methodology was validated through a case study of 203 low volume rural roads in the state of Himachal Pradesh in India. Ranking of these roads in order of their priority for maintenance was presented as the final result.FindingsThe results show that pavement distresses, traffic volume, type of connectivity and the socioeconomic facilities located along a road are the four major factors to be considered in determining the priority of a road for maintenance.Research limitations/implicationsThe methodology provides a comprehensive, scientific and socially responsible pavement maintenance prioritization method which will automatically select roads for maintenance without any bias.Practical implicationsTimely maintenance of roads will also save budgetary expenditure of restoration/reconstruction, leading to enhancement of road service life. The government will not only save money but also provide timely benefit to the needy population.Social implicationsRoad transportation is the primary mode of inland transportation in rural areas. Timely maintenance of the pavements will be of great help to the socioeconomic development of rural areas.Originality/valueThe proposed methodology lays special emphasis on rural roads which are small in length, but large in number. Instead of random, a scientific method for selection of roads for maintenance will be of great help to the public works department for better management of rural road network.
