“…Thus, some of these contaminants such as lube oil, water and sand were tested using different mixes (Fresh and RAP) pavement texture can be classified into three categories according to wavelength of its components, Microtexture, macrotexture, and Megatexture [9]. The correlation between the British Pendulum Number (BPN) and surface texture depth has been investigated by Yager and Buhlmann [10]. The study noted that the variation of BPN is independent on surface texture depth.…”

ÖZKarayolunda 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.Anahtar Kelimeler: Kaplama, yüzey dokusu, ortalama profil derinliği, ortalama doku derinliği, sürtünme direnci. ABSTRACT Evaluation of Surface Texture Properties of Different Types of Flexible PavementsIn order to provide traffic safety on the road, the skid resistance should be at a certain level between the wheel and the surface of the pavement. Skid resistance on which road safety depends is closely related to the pavement surface texture.. The deformations especially the polishing effect seen on the surface of wearing course due to the traffic loads, involves a change in the surface texture. In recent years, efforts are performed to develop more advanced technologies for evaluating pavement surface texture. In this study, the 3D laser scanner was utilized to quantify the mean profile depth (MPD) of 4 different types of

Wet pavement skidding due to inadequate surface texture or friction contributes to 20% to 35% of all wet weather crashes. Many of the past studies of pavement surface texture and friction have deficiency in selecting the model forms or variables and interpreting the models and (or) the findings or have recommended further investigation. These pose a challenge for the highway agencies in selecting the appropriate surface layer and (or) measuring tools. This study was undertaken to re-examine some of the pavement surface texture and skid resistance related issues and aid the highway agencies in this area. Pavement surface texture and skid resistance aspects were carefully examined using the data collected from nine asphalt concrete (AC) surfaces. Pavement surface texture was measured using the sand patch method and a high speed texture laser. Skid resistance was measured using a British Pendulum and a skid trailer. The analysis has reinstated that aggregate quality is the predominant factor for AC surface skid resistance. Both texture depth and ribbed tire skid resistance was shown to increase with an increase in coarse aggregate (CA) content proving their interdependency. Neither the voids in mineral aggregate (VMA) or air voids (AV) contents showed a meaningful or statistically significant correlation with the surface texture or skid resistance. Fairly good correlations were found among the British Pendulum number (BPN), ribbed tire skid number (SN) and mean texture depth (MTD) rejecting the hypothesis that BPN is a measure of only surface microtexture and ribbed tire skid number is insensitive to surface texture.Résumé : Le dérapage sur chaussée mouillée en raison d'une texture ou un coefficient de frottement à la surface inadéquat contribue à 20 % -35 % de tous les accidents par temps de pluie. Plusieurs études antérieures sur la texture et le coefficient de frottement des chaussées présentent des manques dans la sélection des formes ou des variables des modèles et l'interpré-tation des modèles et/ou des conclusions ou encore recommandent de nouvelles études. Cela pose un défi aux ministères des transports quant à la sélection de la couche de surface et/ou des outils de mesure appropriés. La présente étude a été entreprise pour réexaminer certaines questions reliées à la texture de surface des chaussées et à la résistance au dérapage et ainsi aider les ministères des transports dans ce domaine. Les aspects de texture de surface des chaussées et de la résistance au dérapage ont été examinés attentivement en utilisant les données colligées sur neuf surfaces de béton bitumineux. La texture de surface des chaussées a été mesurée en utilisant la méthode d'étalement de couches de sable et un laser pour mesurer la texture à haute vitesse. La résistance au dérapage a été mesurée en utilisant le pendule SRT (skid resistance tester) et une remorque de glissance. L'analyse a confirmé que la qualité des agrégats est le principal facteur de la résistance au déra-page des surfaces de bétons bitumineux. La profondeur de la te...
