ABSTRACT: Edge cracking has been a challenge for the Yukon Government. In an effort to have an improved understanding of shoulder cracking and prevention methods, the Yukon Government partnered with FPInnovations and TenCate Geosynthetics to construct two, instrumented, thin pavement test sites on the Campbell Highway near Watson Lake, Yukon. Both test pavements were treated to mitigate edge cracking with Mirafi® H2Ri, a high strength-woven- geotextile with wicking properties. Project activities included site monitoring of moisture and temperature trends, crack mapping, differential compaction measurement, extended site observation and surveying. It has been concluded that Mirafi® H2Ri is draining moisture effectively. This helped improve the paveMirafi® H2Ri reduced shoulder cracking as well. Other factors (differential compaction and maintenance practices) contribute to edge cracking. This research will provide knowledge about solutions to mitigate pavement distress and reduce maintenance costs.

RÉSUMÉ: Afin d'avoir une meilleure compréhension du mécanisme qui les régit et de les prévenir, construits et instrumentés sur la route Campbell près de Watson Lake, au Yukon, en collaboration avec FPInnovations et TenCate Geosynthetics. Les deux chaussées ont été renforcées avec Mirafi® H2Ri, un géotextile tissé à haute résistance, aux propriétés hygroscopiques. Les activités du projet comprenaient le traitement des données de teneurs en eau et de température, les mesures du compactage différentiel et l'observation du site. Il a été conclu que Mirafi® H2Ri drainait efficacement permet d'améliorer la capacité portante de la structure. Il semble que Mirafi® H2Ri ait réduit la fissuration. autres facteurs (compactage différentiel et les pratiques de maintenance) contribuent à la fissuration. Cette recherche fournira des solutions p de la chaussée et réduire les coûts d'entretien.
