Introduction. On the actual stage of the road sector development the requirements for road marking are increased. Functional durability of road marking depends on the materials quality, marking application technology, its operational conditions. The selection of material is very important.
Problem statement. The most objective method of selecting the materials is their joint test in real conditions of operation. The idea of testing is undoubtedly correct but it is very expensive and time-consuming. The marking of Ukrainian motor roads is arranged using the paint in most cases. In laboratory conditions, it is not possible to determine the usability or unsuitability of the paint for horizontal road marking as no laboratory tests can simulate the impact produced on the road. One of the most important indicators for laboratory conditions for determining the paint’s usability for horizontal marking is the abrasion resistance.
Purpose. Consideration of the possibility of improving the quality of paints and varnishes for road marking by toughening the requirements for resistance to abrasion.
Materials and methods. The article presents the method of determining the stability of paint and varnish materials to abrasion on the Taber abrasion appliance. The method allows obtaining the numerical value of the wear resistance index and the opportunity of their simulation in different laboratories in order to develop the unified and correct understanding of monitoring and repeatability of results. This method could be used for operational determination of paint and varnish material’s quality and the quality of its components in laboratory conditions. Using the Taber abrasion index allows for indirect evaluation of the parameters of used source materials.
Results. The results of the laboratory tests of samples for horizontal marking for determination of abrasion resistance of different paint manufacturers conducted during the last three years are presented.
Conclusion. The obtained actual values of the Taber indicator of paints of various manufacturers comply with the requirements of regulations and are much lower than the standard ones for many samples. The analysis of the actual research results allows concluding that the manufacturers of paints have been observing the stability of the technology of its manufacturing over the past three years. Further research is planned to determine the impact of the formulation components of paints on the indicator of their wear resistance, as well as to prepare proposals on the possibility of adjusting this indicator during the development of amendments to existing regulations.
