Recycling construction waste and re – use in road construction

摘要

Construction activities have a huge harmful influence on environment, caused by the explotation of natural resourcess, production and transportation of materials, construction and demolition and finally the building itself. To minimize construction activities on environment, we need to reduce usage of primary sources and attend to prepare secundary sources. The present work describes recycling construction and demolition waste and re-using in building roads and other construction. In Diploma are present clasifications and characteristics of recycling material, procedure and terms of using recycled material, procedure of recycling, requirement and control of quality, and practical work at recycle construction company. Represented are construction waste, which are caused by constructing and reconstructing roads, railways and infrastructure buildings. Construction waste from industry and energetics also turned on as usable recycled material in construction. Behind all sorts of recycled materials and possibilities of recycling, work parallel represents the solution of this problem in Germany, which is good concept for development in our country. The largest stress in this work is intended to recycle asphalt, re-use asphalt mixture and procedure of re-construction roads.
