Farklı Tip Esnek Kaplamaların Yol Yüzey Özelliklerinin Arazi Ölçümleriyle Değerlendirilmesi

Karayolunda güvenli bir sürüşün sağlanabilmesi için taşıt tekerlek bandajı ile yol yüzeyi arasındaki sürtünme direncinin belli bir seviyede olması gerekmektedir. Sürtünme direnci kaplama yüzey dokusu ile yakından ilişkilidir. Günümüzde, gelişen teknolojinin imkanlarını da kullanarak kaplama yüzey dokusunun belirlenmesine yönelik çalışmalara ihtiyaç duyulmaktadır. Bu çalışmada, İzmir kentinde belirlenen 4 farklı tip esnek kaplamada 3'er aylık periyotlarla 3B lazer tarayıcı kullanarak ASTM E 1845‒09 'e göre ortalama profil derinlikleri (MPD) ölçülmüş, sonuçlar Kum yama yöntemi ile elde edilen ortalama doku derinliği (MTD) ve DFT ile ölçülen sürtünme direnci ölçüm sonuçları ile karşılaştırılmıştır. Çalışma sonucunda MTD ile MPD arasında yüksek korelasyon bulunduğu ve MPD değerindeki azalış oranı ile 60 km/sa hızdaki sürtünme değerinin (f(60)) azalış oranının aynı düzeyde olmadığı tespit edilmiştir.
