Yol yüzey işaretlerinde kullanılan malzemeler ve geri yansıma özellikleri üzerine bir literatür taraması
Ülkemizde şehiriçi ve şehirlerarası yollar inşaa edildikten kısa bir süre sonra yüzey işaretlemeleri yapılarak hizmete açılmaktadır. Bu yolların hizmete açılmasından belirli bir süre sonra bakımsızlıktan veya diğer sebeplerden dolayı yüzey işaretlemelerinin görünürlüğü azalmakta ya da kaybolmaktadır. Yol yüzeyindeki bu işaretlemeler, sürücülerin şerit kullanımı üzerinde görsel bir rehber olma özelliğinden dolayı kazaları önleme konusunda oldukça hayati bir öneme sahiptir. Ülkemizdeki şehiriçi ve şehirlerarası yollarda yol yüzey işaretlemelerine ne yazık ki yeterince önem verilmemektedir. Yolların büyük bir çoğunluğunun yüzey işaretlenmesinin (yüksek kaliteli yollar hariç) ucuz olması dolayısıyla daha çok soğuk boyalar ile yapılması bu işaretlemelerin çok kısa sürede performansını kaybetmesine sebep olmaktadır. Bu durum sonucunda yollarda oluşan karmaşa, şerit disiplinsizliği vb. nedenlerden dolayı birçok trafik kazası meydana gelmektedir. Hâlbuki gelişmiş ülkelerde ülkemizdeki durumun aksine soğuk boya yerine yol ve çevresel şartlara bağlı olarak en uzun dayanıma ve performansa sahip Epoxy, Methyl Methacrylate, Polyester, Termoplastik, Polyurea vb. malzemeler kullanılmaktadır. Bu çalışma kapsamında, gelişmiş ülkelerde yol yüzey işaretlemelerinde aktif olarak kullanılan malzeme türlerinin özellikleri ve kullanım alanları üzerine bir literatür taraması yapılmıştır. Sonuçlar yetkililer ile paylaşılmış ve bu malzemelerin ülkemizde de kullanımı konusunda teşvik edici ve bilgilendirici bir kaynak hazırlanmaya çalışılmıştır.
A literature review on road surface marking materials and retroreflectivity properties
Urban and rural roads are opened to service after the application of road surface markings in Turkey. However, visibility of these roads reduce or disappear caused by the disrepair in a short time after the construction. These road surface markings have a mission to be a visual guide on behavior of lane utilization of drivers. For this reason, it has crucial importance to prevent traffic accidents. Unfortunately, the necessary importance to road surface markings are not given by the authorities in urban and rural roads of Turkey. Generally, standard road marking paint are used in all roads because of its low price and it loses retroreflectivity performance after short time. As a result of this situation chaos, lane indiscipline and many traffic accidents occur in urban and rural roads. Whereas, many different road painting materials are used such as Epoxy, Methyl Methacrylate, Polyester, Thermoplastic, Polyurea etc. to obtain higher performance and resistance according to different road characteristics and environmental conditions. In the scope of this study, a general information were given about the utilization of different surface marking materials which is used in developed countries effectively. Additionally, a number of recommendations and guidance notes have been provided for road makers and decision authorities wishing to use these materials in Turkey.
