“…La cantidad de agua demandada para la dosificación es un factor que se debe manejar con responsabilidad dado los criterios sostenibles que promueven el no comprometer los recursos del planeta para las generaciones del futuro [15], mientras que en lo que respecta al uso del aditivo, su empleo aporta directamente con el impacto ambiental, debido al origen del mismo, resinas naturales [10] . En el proceso de fabricación del producto, se debe considerar opciones para el desecho de materiales de prueba para ensayos o productos que no hayan alcanzado las consideraciones necesarias de diseño, por lo que el desecho de este mortero al ecosistema promueve contaminación ambiental [16].…”

Currently in Ecuador, one of the biggest problems in terms of the road system is the state and conservation of roads, where the consequences that these imperfections bring to the population is notorious. The objective of this project is to develop a mortar based on sugarcane bagasse ash for the repair of roads through the characterization of different materials, the design of dosages and the elaboration of optimized mixtures with additions of ash and zeolite. Given the situation that the country is going through, the opportunity arises to propose a repair mortar that contributes with sustainable and technical criteria. To meet the aforementioned objectives, it was necessary to carry out tests on different materials, which allowed the design of the mixtures of traditional mortar M3, M5 and in turn, of the dosages M -50% C and M -75% C, with variations in the percentage of ash addition in place of sand. The execution of compression, tensile and adhesion tests allowed to evaluate the properties of each mixture and dosage, where maximum values of compressive strength of 17.96 MPa, modulus of elasticity of 2000 Kgf / cm2 and adhesion of 0.52 MPa were determined. The mixture M5 -50% C, which is postulated under different criteria as a proposal for repair material for its best performance among the options that are evaluated, does not meet the parameters required by the regulations of mortars for the repair of rigid pavements.
