COLD ASPHALT CONCRETE PREPARATION TECHNOLOGY Russian patent published in 2023 - IPC C04B26/26 C08L95/00 

FIELD: road construction.

SUBSTANCE: invention relates to a method for producing a cold asphalt concrete pavement for highways. A method for producing a cold asphalt concrete pavement, which consists in introducing a filler and a water repellent stabilizer in the form of elemental sulphur of the Tengiz gas processing plant in a cold state into a previously partially dehydrated plasticizer-solvent in the form of oil sludge with intensive mixing, followed by heating and temperature control at a temperature of 110-120°C, after which a binder preheated to the same temperature is added (bitumen) until a homogeneous mixture is obtained.

EFFECT: improving the indicators of waterproofing properties such as water saturation, swelling, long-term water resistance and caking of cold asphalt concrete pavement, as well as in reducing energy and labour costs for its preparation and expanding the raw material base of mineral components from industrial waste, which reduces the likelihood of environmental risk and allows rehabilitate the areas of their deposition.
