ASPHALTIC MIXTURE CONDITIONER, CONDITIONED ASPHALTIC PAVING MIXTURE, THEIR PROCESSES OF PREPARATION, THEIR USES IN PAVING SURFACES, PAVED SURFACES AND SYSTEM TO PREPARE AN ASPHALTIC MIXTURE CONDITIONER

Document Type and Number:

WIPO Patent Application WO/2021/240216

Kind Code:

A1

Abstract:

The invention refers to an asphaltic mixture conditioner comprising a bitumen, a polyol, a surfactant, a mineral acid and water. The invention further refers to a conditioned asphaltic paving mixture comprising bitumen, aggregate and the said asphaltic mixture conditioner. The asphaltic mixture conditioner, used as an additive, solves problems of the prior art related to bituminous paving composition, which demand a prompt use of the asphalt compositions in situ. The additive contributes to preparation of a conditioned asphaltic paving mixture which may be storage at ambient temperature for longer periods, wherein the additive, at ambient temperature, may be added into a mix of aggregate and bitumen. Before being applied onto a surface, it is heated to a temperature range from 130 ºC to 170 ºC, wherein all the necessary features to properly be applied onto the surface are maintained.
