    In Ecuador, mainly in the rural sector, there are territories that do not have an adequate road structure, where inadequate geometric designs and the lack of flexible pavement structures are present, affecting the growth and development of communities such as Calamaca belonging to the rural parish of San Fernando, since communication turns out to be an important factor in the advancement of a community, fulfilling a social, economic and geostrategic role by influencing equal progress, where the absence of these civil works leads to the isolation of communities, increasing the gap of inequality and poverty between the urban and rural sectors. To this end, the topographic strip was surveyed using topographic equipment consisting of a drone and an RTK, in addition to the study of vehicle traffic from data obtained from the manual counting of vehicles over a period of seven consecutive days including Saturday and Sunday. Also, soil studies were carried out such as: natural moisture content, granulometric analysis, Atterberg limits (liquid limit and plastic limit), modified Proctor and CBR, with which the physical and mechanical properties of the subgrade were determined, in order to carry out the geometric design following the Ecuadorian MTOP and NEVI-12 regulations, in addition to the application of the AASHTO-93 standard for the design of the pavement structure, to finish with the preparation of a reference budget. As a result, a projected TPDA of 141 vehicles/day was defined for a design period of 20 years, classifying the road as a class IV highway. In addition, thicknesses of 5 cm of asphalt layer, 15 cm of base and 25 cm of subbase were determined, established based on the design CBR of 12.5 percent determined with the Asphalt Institute method. Finally, the reference budget of $1,509,526.12 was established, obtained from the Unit Price Analysis of 13 items.
