Restorative and protective materials for road surface treatment

It is possible to prevent or preserve the premature destruction of asphalt-concrete road surfaces by treating the surface with protective and restorative materials. However, the use of existing solutions on this issue often leads to a decrease in the grip of the vehicle wheel with the treated coating, a decrease in resistance to abrasion, which reduces traffic safety. This scientific research is aimed at developing an effective composition of a protective and restorative material. The influence of the degree of modification on the content of petroleum polymer resins in the bitumen binder was evaluated using the developed quality criterion that takes into account the contribution of the content of the modifier. A solvent has been selected that provides effective dispersion and stability of the resulting suspension. The influence of a nanomodifier in the composition of a reducing material on the properties of asphalt concrete, consisting in an increase in crack resistance by 49%, water resistance by 11%, shear adhesion by 6.1%, was studied.
