Road condition and safety is one of the major concerns of users and public agencies. Current investments in**road maintenance are insufficient and will lead to a decline in condition over time. In addition to this, society is**increasingly aware of the need of incorporating sustainable criteria in pavement management. This research**proposal aims to enhance the sustainable use of concrete pavements in Canadian conditions. The overall**objective of this research is to develop and deliver high quality, low maintenance, long-life, sustainable and**resilient pavements to serve the public. In order to achieve this goal, this research will investigate the use of**performance-based specifications in concrete pavement, pavement surface characteristics, application of**concrete pavement in the municipal environment and precast panels for fast track rehabilitation, asset**management and use of recycled concrete aggregates. This specific research projects within this proposal are**directed at improving concrete pavement performance and sustainable asset management, concrete pavement**surface characteristics, and development of innovative concrete pavement designs for provincial and municipal**applications in Canada. The topics covered in this research proposal comprise innovative solutions that address**key 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.

道路状况和安全是使用者和公共机构的主要关切之一。目前对 ** 公路养护的投资不足，随着时间的推移，将导致公路状况恶化。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 ** 建议旨在加强加拿大条件下混凝土路面的可持续利用。这项研究的总体目标是开发和提供高质量，低维护，长寿命，可持续和弹性路面，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使用、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。本提案中的具体研究项目 ** 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，以及为加拿大省和市 ** 应用开发创新混凝土路面设计。本研究提案涵盖的主题包括创新解决方案，解决加拿大水泥协会（CAC），交通部安大略（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。
