Use of Recycled Aggregates in Whitetopping with Addition of Automotive Tires Scraps

Paper by MORALES CUGLER LOPES COSTA FAVARÃO MENDES from ISCR 9th 2004 Instanbul Turkey

The paper presents the results of a study about the use of recycled tire and building materials in concrete for “whitetopping” on asphalt concrete paving. This report presents the results of laboratory experiments and field tests. These results were obtained with concretes using substitution ratios of 15% to 20% by the mass of the sand in tire scrap and 20% to 30% by the mass of the basalt coarse aggregate in recycled aggregate for slump of 40mm. These concretes were tested at 7 days and 28 days and the results obtained were very satisfatories. The study concluded that the recycled tire and aggregate can be used in “whitetopping process”.
