Ph.D. Tezi Görüntüleme

      In this thesis study, the texture abrasion of concrete roads depending on the fine aggregates subjected to tire loads is investigated. A special designed abrasion test setup consisted of tire applying a constant lateral and vertical load on a textured concrete surface was developed. The mix paremeters subjetcted to loading in the test setup were limestone , (%50 limestone + %50 basalt) mix, and basalt fine aggregate. The three main mixes were also diveded and classified into 9 different mixes according to three types of finess modulus. The changes in the friction coefficient, two dimensional profile of the surface texture, and the contact points were measured under 0, 1000, 5.000, 25.000, 100.000 tire passes. It was concluded that, overall the mix with %50 limestone + %50 basalt and bazalt mix will give the best performanse against the concrete friction abrasion under tire loads. The test results showed that there is no strong relationship between sand fineness modulus and friction coefficient.
