Resilient and durable concrete pavements

道路状况和安全是用户和公共机构关注的主要问题之一。目前对公路养护的投资不足，随着时间的推移，将导致状况下降。除此之外，社会越来越意识到在路面管理中纳入可持续标准的必要性。这项研究建议旨在提高加拿大条件下混凝土路面的可持续使用。这项研究的总体目标是开发和提供高质量、低维护、长寿命、可持续和有弹性的路面，为公众服务。为了实现这一目标，本研究将调查基于性能的规范在混凝土路面中的应用，路面表面特性，混凝土路面在市政环境中的应用，以及用于快速轨道修复的预制板，资产管理和再生混凝土骨料的使用。这项建议中的具体研究项目旨在改善混凝土路面性能和可持续资产管理、混凝土路面表面特性，以及为加拿大省政府和市政应用开发创新的混凝土路面设计。本研究提案涵盖的主题包括解决加拿大水泥协会(CAC)、安大略省交通部(MTO)和几个加拿大城市、市政当局和预拌混凝土公司面临的关键问题的创新解决方案。

Road condition and safety is one of the major concerns of users and public agencies. Current investments inroad maintenance are insufficient and will lead to a decline in condition over time. In addition to this, society isincreasingly aware of the need of incorporating sustainable criteria in pavement management. This researchproposal aims to enhance the sustainable use of concrete pavements in Canadian conditions. The overallobjective of this research is to develop and deliver high quality, low maintenance, long-life, sustainable andresilient pavements to serve the public. In order to achieve this goal, this research will investigate the use ofperformance-based specifications in concrete pavement, pavement surface characteristics, application ofconcrete pavement in the municipal environment and precast panels for fast track rehabilitation, assetmanagement and use of recycled concrete aggregates. This specific research projects within this proposal aredirected at improving concrete pavement performance and sustainable asset management, concrete pavementsurface characteristics, and development of innovative concrete pavement designs for provincial and municipalapplications in Canada. The topics covered in this research proposal comprise innovative solutions that addresskey issues faced by the Cement Association of Canada (CAC), the Ministry of Transportation Ontario (MTO)and several Canadian cities, municipalities and ready mixed concrete companies.
