Methodology for determining strategies for pavement preservation

In recent years different schemes of financing for road preservation have been established in Mexico and other nations, where a road or road network is granted as a concession to a company that provides the service during a specific period of time. The concessionaires must meet certain standards of performance throughout the life of the concession, such as Internal Rate of Return (IRI), rut depth, deflections, potholes, skid resistance, among others. Therefore, a methodology is proposed that allows determining in an initial way, preservation strategies throughout the concession period, and carrying out the pavement management using the Highway Development and Management Model (HDM-4). The methodology takes into account the type of road, traffic volume, vehicle classification, indicators such as IRI and rut depth, deflections, cracking levels, as well as the pavement age. The methodology uses mathematical models as well as pavement analysis results to determine the preservation strategies that will be studied in the HDM-4. This methodology may be used by the agencies responsible for conservation of roads, both network and individually.
