Alaşehir (Manisa) Bölgesi Traverten Atıklarının Yol Alttemel ve Temel Tabakalarında Kullanılabilirliğinin Araştırılması

Abstract

In this study, physical and mechanical properties of travertine wastes in Alasehir (Manisa) region were determined and their usability as sub-base and base material was investigated. Within the scope of the research, experiments related to the sub-base and base material properties in the Technical Specifications of Highways (TSH) 2013 were applied to the travertine wastes. These experiments; sieve analysis, weather resistance test with MgSO4, Los Angeles abrasion test, flatness index test, water absorption test in coarse and fine aggregate, liquid limit and plastic limit test, organic material test with NaOH, methylene blue test, clay pellet and dispersible grain ratio test, proctor and CBR experiments. In addition, the unit kilometer transportation cost of travertine waste material was calculated and the effective usable distance was calculated in terms of cost compared to crushed stone material. After all; it is seen that travertine wastes can be used as subbase and base material by meeting TSH 2013 standards. In addition, it is considered that unless a price is paid for the wastes, it is cost effective up to a certain distance and that the use of wastes in the road superstructure will reduce the harmful effects of the quarries to the environment to some extent and thus contribute to the national economy and natural balance.
