Abstract

The present invention relates to a method of improving the incorporation of recycled bituminous products by using at least one surfactant as an alternative to the known rejuvenating oils, for the preparation of asphalt mixes containing recycled bituminous products. The use of such alternative surfactant(s) results in better mechanical properties of the asphalt mix, while using smaller amounts of fresh bitumen and greater amounts of recycled bituminous products.
