    A laboratory evaluation on skid resistance performance of surface coatings manufactured by both natural aggregates and by-products
    (CRC Press/Balkema, 2017) Gökalp, I.; Uz, V.E.; Saltan, M.
    In this study, skid resistance of surface coatings produced with different aggregate and aggregate gradations was investigated. To do so, Limestone, basalt, boulder, electrical furnace steel slags, and ferrochrome slag were supplied. The aggregate gradation used for production chip seal samples were ranging from 19 to 2 mm, and Type I, II and III were used for manufacturing of slurry seal samples. Physico-mechanical and chemical properties of each aggregate were determined with series of standard tests. For chip seal production, 70/100 penetrating grade bitumen modified with adjuvant, DOP, and for slurry seal production cationic emulsion (CRS-2) were used. To measure the skid resistance of samples, British Pendulum tester was implemented according to ASTM E 303. It was concluded that skid resistance performance of surface coatings manufactured with by-products are higher than those produced with natural aggregates. In addition, the skid resistance performances change depending on aggregate grading sizes and gradation. © 2017 Taylor & Francis Group, London.

    Comparative laboratory evaluation of macro texture depth of chip seal samples using sand patch and outflow meter test methods
    (CRC Press/Balkema, 2017) Gökalp, I.; Uz, Volkan E.; Saltan, M.
    In this study, macro texture depth of chip seal were evaluated with Sand Patch (SP) and Outflow Meter (OFM) tests methods. The samples were manufactured according to different types of aggregates (natural and artificially occurred) and chip sizes. The aggregate gradation sizes that in seven single-size (19–2 mm) were used for production the samples. Limestone, basalt, boulder, steel slag, and ferrochrome slag were supplied from southern region provinces of Turkey. For production the samples, 70/100 penetration grade modified was utilized. Certain properties of aggregates and bitumen were determined with series of tests. Were conducted for macro texture depth determination. The study has shown that macro texture depth relative differences between SP and OFM ranges from 10.4% to 36.6% for chip seal samples and coefficient of regression is computed as 0.91. Moreover, 6 mm mean texture depth can be identified as a threshold for implementation of OFM test method. © 2017 Taylor & Francis Group, London.
