ABSTRACT:
The limited possibilities of agricultural utilization of sewage sludge results in the development of unconventional methods of its final management. Recently, the recycling of sewage sludge in road construction is under examination. Literature review mentions that properly prepared sludge might replace other conventional materials which are commonly used in a construction sector. In this paper, the proposition of the use of sewage sludge in the production of unconventional material for a road construction is presented. In laboratory tests, dewatered sewage sludge with the moisture content at the level of 62%, glass powder and quartz sand were applied. For obtained product, physical and chemical characteristics were examined. The compressive strength and the hardness were also measured. Results were compared with other materials which are also used in a construction sector. The research confirmed the possibility to produce a material from different fractions of waste, which might indicate the usefulness in civil engineering.
