USE OF WASTES ORIGINATED FROM THE DEEP EXCAVATION ACTIVITY (CONTINUOUS HELICAL PILES) AND BY DEMOLITION OF OLD CONSTRUCTIONS: TECHNICAL AND ECONOMIC ANALYSIS IN PAVING PROJECT

摘要

The large volume of Construction and Demolition Waste (CCW) generated by construction activities in Brazil has caused environmental, social and economic concern, resulted by the unnecessary exploitation of natural resources by the emergence of clandestine drops, by the proliferation of vectors of diseases, and the expense for transporting and dumping them in landfills legalized. In this scenario, studies have been developed to solve or minimize this problem. In 2004, Brazilian standards were prepared (NBR 15115 and NBR 15116) that govern the use of recycled aggregates concrete RCC without structural function and low traffic paving.
