Optimal Location of Crashing Plants for Transportation of Base Course Material during the Construction Phase: A Case Study from a South American Project

Felipe Araya, Alfredo Vila


The transportation of base-course materials during construction is a challenging process of infrastructure projects, involving sub-processes such as quarrying, crushing, hauling, placement and compaction. The high cost of transporting base-course materials increases the total cost of the construction project. Thus, minimizing the cost of the transportation of base-course material during the construction may improve the performance in terms of highway infrastructure projects cost. This research presents an optimization model based on linear programming of the cost of transportation for base-course material that accounts for costs of extracting material, transportation from the quarry to the crushing plant, the cost of crushing material, transportation from the plant to the field, and the installation in the field. The proposed model is then implemented on a highway project constructed in Peru. The results emphasize the relevance of the location of the crushing plants within the project area and its impact on transportation costs. For instance, in the case study presented, the lowest cost was obtained when installing two crushing plants instead of one. The principal contribution of this study is providing an approach for construction managers and engineers providing better information to make decisions during the planning of base-course construction processes for highway infrastructure projects
