“…The energy efficient additive results in fewer turns needed to ensure the required density. It has been established [19] that at high technological temperatures the additive significantly reduces the viscosity of the bitumen, and, therefore, makes it easier to lay and condense the asphalt concrete mix. At the same time, the viscosity increases at the operational temperature, which leads to better durability, makes the asphalt concrete stronger and more resistant to wheel track rutting.…”

“…On the other hand, when the quality of roads with asphalt concrete surface is enhanced, it is necessary to take into account lower materials-output ratio and energy efficiency of the asphalt concrete mix production. Warm asphalt concrete is one of the materials that fully meet modern requirements for energy efficiency and is environmentally friendly [11][12][13][14][15][16][17][18][19][20][21]. There has been almost no research aimed at the development of warm asphalt concrete mixes on the basis of polymer bitumen binders.…”

The article presents theoretical basis for the use of energy efficient additives for the production of warm asphalt-concrete mixes on the basis of polymer-bitumen binders; the principles are proposed on how to reduce the temperature, when asphalt-concrete is spread by adding energy-efficient additive. It has been established that in terms of its physical and mechanical operational qualities warm Type b polymer asphalt concrete that has been condensed at low temperatures is not inferior to the control samples of asphalt concrete that has been prepared according to the classic recipe.

Heavy oil and vacuum residue were used to obtain road bitumen BND 50/70 using two different methods of steam distillation at 323–362 °C and by oxidation, a method using packed column at temperature of 211–220 °C. The obtained residues using two methods steam distillation and oxidation are known as non-oxidized bitumen and oxidized bitumen, respectively. The products were evaluated using different standards including GOST 33133-2014, GOST 22245-90, and ASTM D5. The results showed that the yield of oxidized bitumen reached a maximal rate of 89.59% wt., while that of non-oxidized bitumen is 55% wt. The softening point of oxidized bitumen is 49–57 °C compared to non-oxidized bitumen (46–49 °C). Remarkably, the previous softening point and penetrability of 47–71 points of oxidized bitumen are consistent with norms to BND 50/70 bitumen, according standard. The non-oxidized bitumen has a relatively low softening point and a higher penetration value of 71–275, which refers to BND 200/300 bitumen. Comparatively, the use of a packed column is beneficial than the steam distillation, due to high capability of the nozzles to strengthens contact between feedstock and compressed air in the reaction zone and decreases the reaction time to 4.15 h.

Obtaining warm asphalt concrete mixes is an urgent task in the road industry, as it allows solving environmental, technological and economic problems of preparing and laying asphalt concrete. One of such technologies is the production of asphalt concrete using organic additives based on synthetic waxes, which until recently were presented on the market exclusively with imported products. In the current political and economic situation, the relevance of the development and implementation of domestic analogues of wax temperature-lowering additives becomes an important task. The article studies the effect of additives based on synthetic waxes on such physico-chemical properties of bitumen binder as penetration, softening temperature, extensibility, fragility temperature by Fraas, adhesion to crushed stone. The indicators and comparative analysis of the properties of binders modified by the domestic complex additive Viskodor PV-2 and imported organic additives Licomont BS-100 and Sasobit are given. It was revealed that the new domestic complex additive has advantages over imported wax additives: it allows to lower the brittleness temperature of the binder, increase the softening temperature, the adhesion of bitumen to mineral materials with a smaller decrease in penetration. Rational concentrations of the use of the additive Viskodor PV-2 have been established.
