ABSTRACT
The generation of solid waste from construction and demolition sites in Denmark is approximately 1.25 million tons/year. Recovery of materials from this type of waste can reduce landfill areas and consumption of gravel resources. Obstacles for an extended recovery exist. A demonstration project is, therefore, conducted to prove the feasibility of on site use of regenerated demolition debris.
An old factory is demolished. The total waste quantity is 8,600 tons. Approximately 3,400 tons of tile and concrete is crushed by a mobile crushing plant. The crushed materials are used for constructing a parking area next to the demolished factory. The crushed materials are analyzed (sieve analysis, density, etc.) at a laboratory. Five different types of pavements are established. The pavements are tested during construction (plate loading, standard proctor, etc.). Laboratory tests show acceptable quality of the crushed materials. The possibilities for on site utilization is verified by the site tests.
