ABSTRACT

One of the key objectives of a pavement management system (PMS) is to find the optimal maintenance strategy, which minimises the sum of a road agency and user costs by maximising the net benefit to society. The PMS helps road agencies to better apply a selection of the right pavement treatments. The objective of the present paper is to show how the HDM-4 (Highway Development and Management 4) approach allows to develop a policy road leading to the optimal and robust selection of maintenance strategies under budgetary constraints, which minimises the sum of agency costs and road user costs in present value or maximises the net benefit to society over an analysis period. The findings could help road agencies to better apply the right pavement treatments. The present study is based on the exploitation of road network data, obtained from pavement structural condition survey and performed by the National Studies and Road Research Center. The study applies a long-term simulation (20 years) of maintenance budget needs under different budget scenarios.

摘要

路面管理系统 (PMS) 的关键目标之一是找到最佳维护策略，通过最大化社会净收益来最小化道路代理和用户成本的总和。PMS 帮助道路机构更好地选择正确的路面处理方法。本文的目的是展示 HDM-4（高速公路开发和管理 4）方法如何允许制定政策道路，从而在预算限制下优化和稳健地选择维护策略，最大限度地减少代理成本和道路使用者的现值成本或在分析期间为社会带来的净收益最大化。这些发现可以帮助道路机构更好地应用正确的路面处理方法。本研究基于对道路网络数据的利用，从路面结构状况调查中获得，由国家研究和道路研究中心进行。该研究对不同预算情景下的维护预算需求进行了长期模拟（20 年）。
