Diatomitin bitümlü sıcak karışımlarda filler olarak kullanılabilirliğinin araştırılması.

In the study, the usability of diatomite as filler in asphalt concrete pavements was investigated. For this purpose, Marshall briquettes were prepared with bitumen content of 3.0-3.5-4.0-4.5-5.0% by using limestone aggregate and crushed stone dust filler. These samples were prepared using the Marshall stability and flow test precedure, and the following results were discovered: stability value, flow value, bulk specific gravity (Dp), percentage of voids (Vf), percent voids filled with asphalt (vfa) and voids in mineral aggregate (VMA). The optimum bitumen content was determined as 4.68% after the relevant graphs were created based on the results of the limestone sample. Based on the optimum amount of bitumen determined and using the same gradation, limestone fillers and diatomite fillers were replaced at the rates of 0, 25, 50, 75, 100%, and diatomite-modified asphalt concrete samples were produced. After the stability, flow, Dp, Vh, Vfa, VMA values of the diatomite filler briquettes were determined, the test results were evaluated. As a result of the research, it was determined that the samples containing 25% diatomite fillers had high stability and acceptable flow values. [ABSTRACT FROM AUTHOR]
