In this research work, the road costanera was developed, located betwenn the districs of Huanchaco (province of Trujillo) and Santiago de Cao (province of Ascope), región of La Libertad, where the design of flexible pavement using the bitufor system (metal mesh + slurry seal, located between the taxiway and granular fundation) as a sustainable measure was carried out, for this, the trip was made to the study area, where the description of the current state of the road was made, evidencing that the current taxiway (micropavement) is in poor serviceability conditions of having multiple flaws and gaps reaching the level of the granular base, hindering the trafficability of vehicles, basic engineering studies were also carried out, where the topographic study allowed to determine the flat orography of the study area; the traffic study indicated an IMDA design of 1,055 vehicles per day, clas...
