This paper presents the properties of hot- and warm-mix asphalt concrete and possible use in pavements using a high rate of RAP (reclaimed asphalt pavement) and waste cooking oil (WCO). Laboratory experiments delivered results on the mixtures’ essential volumetric and Marshall characteristics and their several mechanical performance parameters. These outcomes are used to deliver a mix-design procedure and propose critical recommendations on using that type of asphalt concrete. The paper provides pavement structures for medium/low-traffic roads with hot- or warm-mix asphalt concrete layers with up to 80% of RAP and WCO as a rejuvenator. The paper also includes a direct cost analysis to show the savings achievable with that technology. The results allow us to conclude that the hot- and warm-mix asphalt concrete materials developed in the project are suitable, durable after ageing and cost-effective for medium/low-traffic road pavements.
