Assessment of the Use of Hot-Mix Recycled Asphalt

Hot-mix recycled asphalt concrete in plant is one of the available techniques to perform cost and environmental effective pavement recycling. It is not commonly used in Portuguese paving practice basically because there is a lack of confidence at the end of the production chain. A study was conducted using mixtures from four trial sections, one with a traditional mixture for
