Micropaving in Road Infrastructure: A Systematic Review of the Factors That Limit Its Application

Abstract

Micropaving is an efficient and sustainable alternative for road infrastructure conservation and maintenance; however, its application remains limited in various contexts. This situation is due to multiple factors that restrict its adoption, including technical ignorance, lack of clear regulations, institutional resistance to change, and weaknesses in the training of responsible actors. Therefore, the purpose of this research is to identify, based on a review of the academic literature, the main barriers that affect the use of micropaving, both in road construction and maintenance processes. Methodologically, the study was developed using a qualitative approach, with a descriptive scope and a design based on a document review. The results show that the limitations are related to technical, economic, and administrative factors. It is concluded that it is necessary to design strategies that strengthen the dissemination of knowledge about micropaving and promote its incorporation into public road infrastructure policies, given its proven effectiveness in various international scenarios.
