Usability of Limestone Aggregate Extracted in G�ller Region as Highway Materials

Abstract

In this research some aggregate samples obtaining from Göller region was examined to investigate the usability of limestone as highway materials. For this reason, three quarries including Gümüşgün quarry at the north part of Isparta, Çine at the south part of Burdur and Dağbeli at the north part of Antalya city are visited and the relevant samples are collected. Sieve test, lose density test, specific gravity and water absorption test, freezethaw test, micro-Deval test and aggregate impact value test conducted on the collected samples in the laboratory. Further, Proktor compaction and CBR test applied on the mixtures accrued with dense graded aggregates. As a result of study, it is concluded aggregate samples collected from there different quarries having reliable physical and mechanical properties to be used as highway base and sub-base material. However, aggregate extracted from Dağbeli quarry would be better to use in the mild climate regions instead of cold and severe weather regions. On the other hand, Gümüşgün aggregate that is abrasion resistant and strength properties indicates higher values than others so it may also be used as a hot mix asphalt aggregate.
