On majority of roads, horizontal road markings are essential safety feature that must be periodically renewed to maintain appropriate performance. The use of a premium road marking system resulted in prolonged the service life as compared to a standard system, which would be financially-neutral in the long term despite much higher unit and initial costs; advantageously, 54% less glass beads and 63% less paint would be required over 10-year life cycle. When these products usage savings are recalculated into raw materials consumption, the premium system would demand about 21% more of titanium dioxide, but that would be offset by approximately 25% reduction in the consumption of acrylic resin and circa 97% reduction in organic solvents usage and emissions. The results from this analysis can be used by road administrators to select the best systems, by policy makers seeking minimisation of environmental impacts, and by contractors who won performance tenders.

结构化水平道路标记的材料选择：财务和环境案例研究

在大多数道路上，水平道路标记是必不可少的安全功能，必须定期更新以保持适当的性能。与标准系统相比，使用优质的道路标记系统可以延长使用寿命，尽管标准系统的单位成本和初始成本要高得多，但从长远来看，这在财务上是中立的；有利的是，在10年的生命周期中，需要的玻璃珠减少了54％，油漆减少了63％。当这些产品的使用节省量重新计算为原材料消耗时，高级系统将需要多出约21％的二氧化钛，但这将被丙烯酸树脂消耗量减少约25％和有机溶剂用量减少约97％所抵消。和排放。道路管理员可以使用此分析的结果来选择最佳系统，
