摘要

The University of Waterloo’s Centre for Pavement and Transportation Technology (CPATT) is committedrnto working with public and private sector partners to develop sustainable technologies. Recycled AsphaltrnShingles (RAS) is a product that contains approximately 30 percent asphalt cement by mass. Sources ofrnRAS include trimmings from shingle insulation and decommissioned shingle roofs. Reuse of thesernmaterials leads to financial savings through the avoidance of disposal costs and reduction of the amount ofrnvirgin asphalt binder required in Hot Mix Asphalt (HMA). This paper presents results from a recent studyrninvolving Miller Paving Limited, CPATT, and Materials Manufacturing Ontario (MMO). In addition thernécole de Technologie Superieure (ETS) in Montreal was involved in the project as a subcontractor tornCPATT, carrying out some of the sample testing.rnTo compare the various mix designs the dynamic modulus test, resilient modulus test, Thermal StressrnRestrained Specimen Tensile Strength Test (TSRST), and French wheel rutting test were run for five mixrndesigns incorporated varying percentages of RAS and Reclaimed Asphalt Pavement (RAP). Overall thernresults are very encouraging and have led to several field placements. Initial analysis of these fieldrnplacements is also presented
