road construction

Modifying road bitumen of the BND 70/100 brand with humic acids was carried out. In particular, the influence of the duration of the process and the amount of addition on the quality characteristics of the binder was studied. It was established that humic acids negatively affect the plastic properties of bitumen (deteriorate the softening temperature, penetration, and ductility), positively affect its elasticity, and have practically no effect on the ability of the binder to adhere to the surface of the mineral material.

Ukraine's transition to an energy-efficient economy as part of its overall transformation to EU standards is a difficult but crucial challenge. The country's post-war recovery will involve modernizing the entire infrastructure in line with EU sustainable development standards.

The results of literary studies on the level of ash-slag waste accumulation, its low utilization and use in Ukraine are presented. The results of previous years’ research are shown, which indicate the possibility of their wide application in road construction. The main reasons for inhibiting the use of ash-slag waste in the road industry are indicated.

The findings of a study of the consolidation of barren rocks from the mines as well as recommendations for the technology of constructing road coatings are presented.
