Comparative Evaluation of Sustainability Models in Pavement Infrastructure: A Reference Model for the Peruvian Highlands

Resumen

A current challenge in civil engineering is that infrastructure projects are sustainable throughout their life cycle, thus contributing to the sustainable development of the country. Peru is a country where economic investments in road infrastructure projects are increasing more and more, so there is a challenge to integrate sustainability into pavement infrastructure projects. Currently, Peru lacks a model that evaluates the sustainability of pavement infrastructure projects in its mountainous areas, whose temperatures are extreme and with intense rainfall due to its altitude and rugged topography. The objective of this research is to select a reference evaluation model, based on a comparative documentary analysis of three existing sustainability evaluation models that are applied to pavements in the different phases of their life cycle and to carry out a critical analysis of the reference model focusing on its capacity to evaluate pavement infrastructure projects in a context such as the Peruvian mountainous areas. The method used is deductive, with a qualitative approach, descriptive level, framed in a non-experimental, documentary, transversal design. In the research, a comparative analysis of three certified sustainability assessment models such as CEEQUAL, IS RATING SCHEME and GREENROADS was carried out throughout the life cycle phases and in various dimensions and key indicators. As a reference model, it was determined that the GREENROADS model is the most suitable to evaluate the sustainability of pavement infrastructure with conditions in the mountains of Peru, given its technical and specialized approach to pavements and its comprehensive sustainability assessment in extreme conditions.
