    The Pelileo – Guayaquil road holds significant importance as it is situated between two cantons, Quero and Pelileo, and plays a crucial role as a transportation artery. Currently, it exhibits deficiencies that adversely affect the quality of life for the residents in the area. By enhancing connectivity between these two urban centers, the road becomes a key axis for the efficient distribution of goods, directly contributing to trade and the economic dynamics of the region. A methodology combining both quantitative and qualitative approaches was employed, guided by ASTM, AASHTO, and MTOP standards, providing a more reliable focus and assurance of effectiveness to the study. Data on both surface and structural deficiencies were collected through laboratory and field studies, using methods such as TPDA, which revealed that the road exhibits characteristics of a Type I highway. The PCI indicated a poor condition, and granulometry and Atterberg limits identified it as composed of fine sand (A3) and Class 4 Base. Modified Proctor and CBR tests indicated that the bearing capacity of these materials falls within a good range of 19-26 and 80-85 percent, respectively. These data were essential for formulating a maintenance plan to address these deficiencies. The results underscored the need for road maintenance, ranging from routine upkeep to reconstruction. Laboratory studies aided in determining the road's composition, a factor considered to reduce construction costs.
