Résumé

The RILEM technical committee on Performance-based Asphalt Recycling TC 308-PAR focuses on research, knowledge exchange and dissemination on the asphalt material recycling. Specifically, the Task Group 1 (TG1) “Performance-based Evaluation of Cold Recycled Asphalt Mixtures” aims at matching laboratory testing methods with the in-service behavior of cold recycled asphalt mixtures. In this context, the TG1 members collaborated to share the different cold recycling procedures used in their respective countries, with the goal of comparing specific practices, technical requirements, and performance expectations. Considering the different areas of expertise and application environments, such as road type, traffic volume, climate and material resources, the information gathered provides a broad framework of the current practices and prospects a widening of future application of cold recycling techniques. The comparison among country practices was divide into two papers: Part I dealing with constituent materials and common mixture composition and requirements and Part II treating testing procedures and mechanical characteristics. Particularly, Part I reports a critical comparison between standard frameworks for reclaimed asphalt (RA), cold recycling practices, materials and mixtures used in Italy, Canada, Poland, Brazil and USA, either adopted by selected road administrations or established by reference standards.
