Abstract

Introduction. Decision the tasks of effective functioning of surface dressing of roads of Ukraine with the use of modern methods carried out in European countries, in particular tests in accordance with EN 12272-1: 2021 (EN 12272-1: 2002, IDT) Surface dressing — Test methods — Part 1: Rate of spread and accuracy of spread of binder and chippings. Problem statement. One of the prerequisites for the effective functioning of the road network of Ukraine is, first of all, the introduction of the road industry the requirements of the Association Agreement between Ukraine and the EU. In order to implement the requirements of this Agreement, which are the key principles of economic modernization and sustainable development of the country, «DerzhdorNDI» SE has prepared a comprehensive set of national standards with an identical degree of compliance with European requirements in the direction of solving the problems of effective functioning of the surface dressing of the pavement. Purpose. The purpose of this work is to promote the implementation in the road industry of Ukraine of the requirements of the national standard DSTU EN 12272-1:2021 (EN 12272-1: 2002, IDT) «Surface dressing — Test methods — Part 1: Rate of spread and accuracy of spread of binder and chippings» which is being prepared for publication by the National Standardization Body of Ukraine and enter into force with 01.07.2022. The related requirements of this standard DSTU EN 12271:2021 (EN 12271:2006, IDT) «Surface dressing. Specifications» discussed in the article «European practice of solving the problems of effective functioning of surface dressing. Part 1. Materials and methods. Analysis of the national standard DSTU EN 12272-1:2021 (EN 12272-1:2002, IDT) Surface dressing - Test methods - Part 1: Rate of spread and accuracy of spread of binder and chippings with an identical degree of compliance with EN 12272-1:2002 (version en) «Surface dressing — Test methods — Part 1: Rate of spread and accuracy of spread of binder and chippings». Results The requirements of the national standard for the effective functioning of the surface dressing of roads in Ukraine are considered, further use of which provides an opportunity to improve the performance of works for its arrangement. Conclusion. The use of this standard will be promote the introduction of various on test methods used to rate of spread and accuracy of spread of binder and chippings, as well as indirect assessment of the quality of equipment for their distribution in the case of surface treatment. Requirements provide an opportunity to use quite simple toolkit, under consideration in this article, and which should be used in the road industry of the country. Based on the provisions of the standard, practical recommendations can be developed in order to implement test methods for the installation of surface dressing. The introduction of these principles will promote the competitiveness of products of national producers, who have to produce samples or ancillary equipment, the use of which is given in the standard, given the needs and priorities of national customers
