Around the world, clay soils and their changes in volume have been a major problem for infrastructure works, since in addition to causing serious structural damage to buildings, road works, water and sewage systems, among others, they have generated large economic losses for the executing entities. Therefore, for the execution of road works, it is essential to know the characteristics of the subgrade on which the pavement structure rests, so that if these do not meet the minimum requirements demanded by the Highway Manual - Soils and Pavements Section, an improvement to the soil properties called stabilization would have to be made. For this reason, a study was made of the characteristics of the subgrade in the urban roads of P.J. Antonio Raymondi del Acqua and the influence that the asphalt emulsion and the steel chips had on them. The natural soil samples extracted according to the SUCS classification are of the CL type, in general the samples presented CBR at 95% of the low M.D.S., whose minimum value obtained was 1.9% belonging to test pit 02, the sample with which the tests with the additives were carried out. Regarding the results of the tests on the samples with the addition of steel chips, soil stabilization was only achieved with 15% of addition, achieving a CBR of 5.5%; on the other hand, with the asphalt emulsion, stabilization of the clayey soil was achieved with the dosages of 3%, 6%, 9% and 13%, with the latter obtaining a peak of 6.4% of CBR, and then descending with the dosage of 18% of addition of asphalt emulsion below 3%. As for the economic analysis, the design of the flexible pavement with the addition of steel chips and asphalt emulsion was carried out; in both cases, the cost of base and subbase was reduced by 79.2% and 58.5%, respectively, compared to the design without additives.
