Conservation of flexible pavement using the PCI method

Abstract

The systematic review studied the effectiveness of flexible pavement preservation using the Pavement Condition Index method, the scientific literature of the last 05 years was analyzed through an exhaustive search in databases and those that met the inclusion criteria were selected. The objective of the research is to examine previous studies on the application of the PCI method in flexible pavement preservation programs to determine its effectiveness. An advanced search was carried out in databases such as Scopus and Web of Science in order to obtain a bibliometric record with background information to facilitate the research. The main focus was on articles that respond to the general question, present coherence, show the research objectives and have a methodology oriented to the central theme; As a result of the research, 19 articles were selected and entered in the search matrix and it was identified whether they met the relevance criteria such as the dimensions similar to the general topic. The review analyzed some limitations and areas for improvement in the application of the PCI method, these include the need to establish clear principles for the definition of the different categories of the index, as well as the standardization of the evaluation procedures, the importance of planning and continuous monitoring of the conservation measures to guarantee their long-term effectiveness was highlighted.
