The increase of the Brazilian vehicle fleet highlights the discussion about road infrastructure, especially the construction, expansion or rehabilitation of the existing roads. In this context, it is noted that the Mario Quintana highway (ERS- 118) shows poor conditions of conservation and trafficability, coming mainly from the high degree of deterioration of the constituents of the concrete pavement slabs. The objective of this study was to determine the integrity of this highway, following an evaluation and analysis of pathological manifestations of concrete pavement. Based on the method developed by the U.S. Corps of Engineers (USACE) through the pavement condition index (PCI), the work was divided into three parts: (a) method of evaluation, (b) result analysis and (c) conclusion. The results indicate that the highway has no more functionality and service life, consequently, consummated.
Keywords: pathology, concrete pavement, highway ERS-118, ICP method, trafficability.
