Abstract
GARCIA HERNANDEZ, Fidel; DELGADO ALAMILLA, Horacio and CAMPOS HERNANDEZ, Domingo Eduardo. Influence of design variables on the mechanical properties of a stabilized base with foamed asphalt. Infraestructura Vial [online]. 2018, vol.20, n.35, pp.5-11. ISSN 2215-3705. http://dx.doi.org/10.15517/iv.v20i35.34829.
The construction and conservation of new roads requires many natural and economic resources, so the recycling is one of the most used techniques currently, so it is important to understand the mechanical properties of the type of application to be used.
The present paper focuses on the evaluation of the mechanical properties of a stabilized base with foamed asphalt (cold recycled). The study analyzed the influence of two design variables such as the type of active filler (lime and cement) and the content of foamed asphalt (2.2 to 2.4%). The parameters used in the evaluation were indirect tensile strength, friction angle and cohesion (triaxial test) and resilient modulus (MR).
The results indicate that the addition of lime improves the mechanical properties of the stabilized base. Regarding mechanical parameters, it was observed that the stabilized mixtures with foamed asphalt show an increase in their resistance compared to a granular base, being the loss of cohesion the failure mode of this type of stabilization.
Keywords : Foamed asphalt; tensile strength; stabilized bases; triaxial test; resilience module.
