FIELD: building materials; civil engineering. SUBSTANCE: method involves obtaining bitumen by means of heating and oxidizing petroleum tar by its delivering in the lower part of at least three sectional reactor through sleeve combining tar supply with discharging bitumen concurrently with water supply in the process of tar oxidation through the upper part of the reactor, controlling water temperature, reactor temperature and finely dividing the mixture in each section. Water supply is carried out through nozzles which number is not less than the number of dispersers. Further, bitumen having working temperature is mixed with mineral ingredients. Rubber crumb, surfactants, sulfur or sulfur- containing waste products are used as additives. Raw materials for producing viscous road bitumens are used as tar. Rubble, sand, mineral powder are used as mineral ingredient. Petroleum residuals are heated, before being oxidized, with smoke gases at temperature not greater than 500 C and oxidized at 205-235 C. Transportation structures are erected by means of preparing ground bed followed by laying structural layers of the base and/or intermediate supporting bearing members and one or two layered coating manufactured from the obtained asphalt concrete mixture. The base is manufacturable from monolith concrete or reinforced concrete or precast concrete or reinforced concrete plates or precast-monolith. Transportation structures are repaired and/or restored by means of clearing and at least partially removing the worn-out asphalt concrete and/or applying adhesive primer layer with following pouring the obtained asphalt concrete mixture and its condensing. Removal of partially worn-out asphalt concrete is made in the form of recesses and grooves, arranged at a given angle in plan with respect to longitudinal axis of roadway. Primer like liquid bitumen is produced by obtaining viscous bitumen by heating and oxidizing petroleum tar followed by its liquefaction. Diesel fuel, solar oil, kerosene or kerosene and solar oil mixture are used as liquefying agent. EFFECT: lowered power consumption; enhanced technological effectiveness. 39 cl
