The reduction in consumption of natural resources (fuel, gas, etc.) and contaminant emissions (CO2, CO, NOx, etc.) during the
production of asphalt mixtures has become one of the main challenges in road engineering. Warm mix asphalts (WMAs) have
been developed in order to achieve this objective while ensuring the mechanical performance and durability of traditional hot mix
asphalts (HMAs). However, these materials are commonly manufactured using additives or products whose production could
reduce both their environmental benefits and cost effectiveness. /is paper presents a research study that aims to analyse the reuse
of zeolite wastes derived from petroleum refining in the production of warm mix asphalts. For this purpose, two different types of
zeolite wastes were analysed as additives for the manufacture of two warm mix asphalts, whose mechanical performance was
compared with conventional WMA and hot mix asphalt. /e results indicate that zeolite wastes with a lower particles size
presented higher capacity to absorb water, while its dosage at 0.3% allows for producing warm mix asphalts at temperatures
around 145°C, with comparable workability and densification to conventional HMA at 165°C without reducing its bearing
capacity, fatigue life, and resistance to water action and plastic deformation.
