Presented is 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.

Additive for asphalt mixes containing reclaimed bituminous products

Provided is a composition including at least one bitumen and at least one additive as defined herein. The composition provides emulsions of all types of bitumens, which can be used in the production of cold-poured mixes, having an improved internal strength and a rapid increase in cohesion.

Composition comprising one or more particular additives

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.

The present invention relates to bitumen additive mixtures, their use and application for the fabrication of asphalt mixtures used in pavement and waterproofing, and more specifically for construction, repair and maintenance of sidewalks, roads, highways, parking lots or airport runaways and service roads and any other rolling surfaces.

Additive mix for asphalt mixture preparation

The present invention relates to a bituminous composition comprising at least one bitumen and at least one polycondensate capable of forming a supramolecular assembly comprising one or more associative group(s). The present invention also relates to the use of such bituminous composition for the preparation of asphalt mixtures useful for the coating of rolling surfaces, for the preparation of water-proofing coatings, and the for the preparation of adhesive formulations.
