In Peru there are areas affected by volcanic geology and that have natural inputs called volcanic ash. This is a material formed by small fragments of siliceous lavas of fine grains of whitish, soft and delectable colors. They usually present varying degrees of cementation, of the fisile type, which identifies them in the category of collapsible soils. That is why, for the construction of the pavement it is necessary to perform the stabilization or improvement of the subgrade for the next project that is developed between Arequipa and Moquegua. The purpose of this research is to evaluate the use of marginal aggregates with volcanic ash for the design of the loss of referred hydraulic concrete, which will be determined as a structure with the results of the flexural and critical stress module. The results showed that, in the characterization of fine aggregates containing volcanic ash, they do not require all the requirements proposed in the Peruvian standard (EG-2013) of the road manual. However, the American Concrete Institute (ACI) incorporates the specific conditions of the aggregates, which allows its use based on compliance with the required strength and durability. It was proposed to design a concrete mix for a theoretical strength of f´c = 280 kg / cm2. However, when testing the probes after 28 days of curing, a resistance of f'c = 380 kg / cm2 was obtained, due to the close positive relationship between volcanic ash and the pozzolanic cement used for the mixture.
