Experimental Investigation of Usability of Treatment Sud Ash with Road Filling Materials in Highways

Increasing environmental pollution due to the rapid increase in world population is one of most important problems humanity, perhaps even first. Environmental elements that are vital for living things air, soil and water becoming more polluted unusable day by day. For this reason, various improvement studies carried out these areas. One them wastewater treatment plants built control pollution. While treated sedimentation ponds facilities recycled into nature, it leaves waste sludge behind. These sludges collected a certain place destroyed methods such as composting, drying or incineration. In previous studies, usability sewage ash was investigated. study, road filling material investigated (Ash added clay determined percentages. percentages respectively; 0%, 2.5%, 5%, 7.5%, 10%, 12.5% 15%). Treatment obtained from Bursa Fluidized Bed Sludge Incineration Energy Recovery Facility. Then, samples prepared adding at rates were subjected CBR test with Standard Proctor test. The values result experiments compared given Highways Technical Specifications whether they suitable material. engineering properties used indicate weak (clay soil). an additive has improved all extent.
