项目摘要

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.

道路状况和安全是用户和公共机构的主要关注点之一。当前投资道路维护不足，随着时间的流逝，病情下降。除此之外，社会是越来越意识到需要将可持续标准纳入人行道管理。这项研究提案旨在增强在加拿大条件下混凝土人行道的可持续使用。总体这项研究的目的是开发和提供高质量，低维护，长寿，可持续性和为公众服务的弹性人行道。为了实现这一目标，这项研究将调查使用混凝土路面，路面表面特征的基于绩效的规格，应用市政环境中的混凝土路面和快速康复的预制面板，资产回收混凝土聚集体的管理和使用。该提案中的这个具体研究项目是旨在改善混凝土路面性能和可持续资产管理，具体人行道表面特征，以及针对省和市政的创新混凝土路面设计的开发加拿大的申请。该研究建议中涵盖的主题包括针对解决的创新解决方案加拿大水泥协会（CAC），安大略省运输部（MTO）面临的关键问题以及加拿大的几个城市，市政当局和现成的混合混凝土公司。
