Who Though Recycled Asphalt Shingles (RAS) Needed to Be Landfilled? Using RAS in Asphalt

Recycled Asphalt Shingles (RAS) is a product that contains approximately 30 percent asphalt cement by mass. Sources of RAS include trimmings from shingle insulation and decommissioned shingle roofs. Reuse of these materials leads to financial savings through the avoidance of disposal costs and reduction of the amount of virgin asphalt binder required in Hot Mix Asphalt (HMA). This paper presents results from a recent study involving Miller Paving Limited, University of Waterloo's Centre for Pavement and Transportation Technology (CPATT), and Materials Manufacturing Ontario (MMO). In addition the Ecole de Technologie Superieure (ETS) in Montreal was involved in the project as a subcontractor to CPATT, carrying out some of the sample testing. To compare the various mix designs the dynamic modulus test, resilient modulus test, Thermal Stress Restrained Specimen Tensile Strength Test (TSRST), and French wheel rutting test were run for five mix designs incorporated varying percentages of RAS and Reclaimed Asphalt Pavement (RAP). Overall the results are very encouraging and have led to several field placements. Initial analysis of these field placements is also presented.
