Resumo(s)
Paving with recycled aggregates has already been widely carried out in some countries where there is already consolidated knowledge on the subject. This work
analyzes in the laboratory the physical and mechanical behavior aspects of recycled aggregate in concrete mixes for rigid pavements. After selective collection at a
construction site, the waste undergoes a crushing process, subsequent to granulation and separation into fractions to be used again in the realization of a new mixture
with 40 and 100% replacement of natural gravel for recycled with the addition of structural concrete fi bers that decrease shrinkage and increase fi nal strength. In the
same mix, these mixtures were compared with a conventional mixture that obtained better performance and presented greater compressive strength. The study sought to
analyze the technical feasibility of using recycled material, testing the thickness of several concrete slabs for application on the pavement. Thus, it is concluded that the
analyzed recycled aggregate is of promising use in hard pavement coating, as it presents a compressive strength superior to 25 MPa.
