Rehabilitation study of a heavily trafficked urban road
Description
Rehabilitation of urban roads is usually carried out with special restrictions in order to limit traffic congestion and to assure the link between different routes through the urban areas. Therefore, the user costs resulting from the rehabilitation works should also be taken into consideration in the project phase. The present paper focuses on the analysis of a heavily trafficked urban road rehabilitation project. The original pavement design did not take into account the current traffic levels which are well above the initial values. The pavement is reaching failure in several areas and needs urgent measures to avoid complete failure. The pavement condition is also a result of lack of structural strength and a deficient drainage. Different pavement rehabilitation alternatives were assessed in order to choose the best solution, which should improve the bearing capacity of the pavement, through the rehabilitation of the existing layers and the improvement of the drainage systems, in order to minimize the maintenance operations in the future. The rehabilitation alternatives were also analyzed in terms of the impact of the maintenance operations in the environment.
