Experimental and ANN analysis of temperature effects on the permanent deformation properties of demolition wastes

Abstract

The aim of this research is to study the effect of temperature and stress levels on the permanent strain of blends of two types of recycled waste materials, namely recycled concrete aggregate (RCA) and reclaimed asphalt pavement (RAP). RAP was mixed with RCA in different percentages of up to 80% by dry mass. A three-stage repeated load triaxial (RLT) testing procedure was employed for evaluation of permanent strain of RCA/RAP blends in different stress paths and temperatures. The tests were conducted at different temperatures of 5 °C, 20 °C (room temperature), and 50 °C, to assess the behavior of blends in a wide range of temperatures. The addition of RAP was found to result in an increase o..
