Use of Post-Fabrication Asphalt Shingles in Stone Matrix Asphalt Mix (SMA-10): Laboratory Characterization and Field Experiment on Autoroute 20 (Quebec)

In Quebec, the use of post-fabrication asphalt shingles in pavement construction has been permitted since 2005. The percentage of asphalt shingles is limited to 3 percent by weight for surface courses and to 5 percent for base courses. In addition, the use of Stone Matrix Asphalt with a Nominal Maximum Aggregate Size of 10 mm (SMA-10) has recently been standardized in Quebec. MTQ Standard LC-4202 describes the mix design criteria for SMA-10, which usually contains asbestos fibres. An SMA-10 mix containing 4 percent post-fabrication asphalt shingles designed according to MTQ Standard LC-4202 has been characterized in the laboratory. The experimental study included testing for fatigue, rutting, low-temperature cracking, and complex modulus. The preliminary results show that asphalt shingles may successfully replace asbestos fibres in SMA-10 and reduce the percentage of virgin binder in the mix. In 2006, a test road section using SMA-10 with shingles was constructed on Autoroute 20 near Drummondville. After two years of service, the test section exhibits good behaviour based on various service criteria, such as rutting, cracking, ravelling, and weathering. This paper will present and discuss the results of the experimental work, including issues pertaining to mix design, production, construction, field observations, and measurements.
