摘要

道路标记是几乎所有道路上必要的安全特征。为了达到适当的性能，它们必须用玻璃珠反射。为了展示传统和现代薄层道路标记解决方案之间的差异，在现场比较了四种道路标记系统。根据反射率的测量，估计了玻璃微珠和涂料对使用寿命的影响。使用高性能水性涂料与优质玻璃珠反射，允许耐久性延长六倍以上。财务分析表明，与购买现代材料相关的大量额外费用通过延长使用寿命完全抵消:从长远来看，甚至可以实现65%的节省。随后在光学显微镜和扫描电子显微镜下对使用过的玻璃珠进行分析，提供了有关其表面的信息;观察完好和破损的玻璃微珠。令人惊讶的是，受损的玻璃珠被发现具有类似陨石坑的表面特征，而不是预期的划痕。

A study of premium glass beads for road marking materials

Road markings are a necessary safety feature on almost all roads. For appropriate performance they must be reflectorised with glass beads. To demonstrate the differences between traditional and modern thin-layer road marking solutions, four road marking systems were compared in the field. Based on measurements of retroreflectivity, influence of glass beads and paint on service life was estimated. The use of high-performance waterborne paint reflectorised with premium glass beads permitted for over sixfold extension of durability. Financial analysis demonstrated that the considerable additional expense associated with purchase of modern materials was fully offset through increased service life: even 65% savings could be realised in the long term. Subsequent analysis of the used glass beads under optical and scanning electron microscopes provided information about their surface; intact and damaged glass beads were observed. Surprisingly, damaged glass beads were found to have crater-like surface features instead of the expected scratches.

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.
