dc.descriptionThe cyclic CBR (cCBR) can be an alternative test method to estimate the Resilient Modulus (Mr) of soft subgrade soils, in a relatively inexpensive and simple way. This paper presents a comparison of the results obtained for Mr, following the test standard of the Instituto Nacional de Vías, INV-156-13 “Resilient Modulus of Soils and Aggregates”, whose reference standard is the AASHTO T 307 Standard Method of Test for Determining the Resilient Modulus of Soils and Aggregate Materials), with the Equivalent Modulus (E_equi) of undisturbed clay samples from the lake area of the city of Bogota, obtained in the cCBR test, mainly adapted from the proposal presented by researchers from the University of Delft. The results show that the cCBR test is presented as a viable option to estimate the Mr from the Eequi of soft clays, with a reliability of 95 %.

Los resultados muestran que la prueba de cCBR es una opción viable para estimar el Mr a partir del Eequi de arcillas blandas, con una confiabilidad del 95 %.
