Abstract
Road markings are a necessary safety feature that guides drivers. For visibility in darkness, when accident risk and severity are the highest, road markings must be reflectorised with glass beads to be visible when vehicle headlights shine on them. Renewal of thick-layer structured road markings that have lost retroreflectivity but have retained the structure mostly intact is performed through application of thin-layer paint coatings. Based on a field experiment, it was demonstrated that selection of premium glass beads profoundly extends the durability of the renewed markings, which could be further enhanced through the use of high-performance waterborne paint. Whereas the standard system based on solventborne paint and typically used glass beads failed after a single winter, the use of premium road marking system at least doubled the service life. The extended road marking service life translates to 50% savings in material consumption, 50-97% lower emissions of volatile organic compounds, and a decrease in long-term financial expense by 5-26%.
期刊介绍：
The quarterly journal Roads and Bridges – Drogi i Mosty is published by the Road and Bridge Research Institute since September 2012 as a bilingual English-Polish journal. From 2002 to 2012 the journal was printed under the title Drogi i Mosty. The journal mission is to promote current achievements in science and technology in the field of road and bridge engineering. The journal is intended as a forum of the exchange of innovative concepts and solutions between the researches from different countries. Original scientific and technical papers in the field of civil engineering and related engineering sciences are published. The scope of Roads and Bridges – Drogi i Mosty includes design, construction, maintenance and safe use of roads, bridges, airports and other transportation structures.
