    Due to the poor condition of the asphalt layer of the road under study, the road rehabilitation plan is presented, which consisted of a georeferenced survey, using a GPS, a digital model of the road was built, the estimation continued through the location of a counting station for 7 days in 12-hour periods, the future TPDA was estimated for the road in a period of 20 years, maintaining its road classification according to the MTOP as a class III collector road. Through laboratory tests of the samples obtained every 1.0 km, it was found that the predominant type of soil on the road is "Silty Sand", with a general classification of CBR as "Good" subgrade. With the use of the Benkelman beam, a type of deflection III was obtained, which presents a "good" behavior of the subgrade and a "bad" behavior of the pavement. The determination of the state of the pavement consisted of a visual inspection considering the different types of anomalies existing on the road, ending with a total PCI of 30.86 percent, classifying the state of the road as "bad", requiring rehabilitation. The proposal to follow consists of a rehabilitation of the complete structure of the road, which includes 6 necessary items for a monetary value of 731,450.72 dollars, in order to improve the current state of the road and the safety and comfort of drivers.
