While snow removal in urban areas involves considerable costs, the transport efficiency of a city can bestrongly delayed by accidents and repairs. The methods currently employed for assuring winter mobility inregions with severe climate conditions consist mainly in the application of de-icing salts to roadways andsidewalks, and the clearing by mechanical snowplow. While the use of road salts for de-icing is an effectivemethod for ice removal, it causes damage to concrete and corrosion of reinforcing steel in strategicinfrastructure systems, such as concrete bridge decks. Thus, snow removal is one of the major causes of therapid deterioration of Canadian infrastructures. As alternative solution, Electrical Conductive Concrete hasbeen recently optimized at Université Laval for rapid heating slabs, with low installation and repair cost.This project focuses on the development of an efficient sensor-based control of an ECC pavement to clearsnow and ice in the context of modern intelligent cities. By taking advantage of the recent ECC mix designdeveloped at Université Laval (9), the objective of this project is twofold: (1) optimize the design of the ECCpavement with respect to the electrical system; (2) develop a sensor-control system for an efficient ECCpavement. The project is based on experimental campaign on small ECC slabs and large ECC slab in realenvironmental conditions for optimizing and verifying their energy efficiency as snow removal systems.

虽然城市地区的除雪需要相当大的成本，但城市的交通效率可能会因事故和维修而严重延迟。目前，在气候条件恶劣的地区，保障冬季通行的方法主要是在道路和人行道上撒除冰盐以及机械扫雪机清理。虽然使用道路盐除冰是一种有效的除冰方法，但它会导致战略基础设施系统（例如混凝土桥面）中的混凝土损坏和钢筋腐蚀。因此，除雪是加拿大基础设施迅速恶化的主要原因之一。作为替代解决方案，拉瓦尔大学最近对导电混凝土进行了优化，用于快速加热板，安装和维修成本低。该项目重点开发基于传感器的 ECC 路面高效控制，以在现代智能城市的背景下清除冰雪。通过利用拉瓦尔大学 (9) 最近开发的 ECC 混合设计，该项目有双重目标：(1) 优化 ECC 路面的电气系统设计； (2) 开发用于高效 ECC 路面的传感器控制系统。该项目基于在真实环境条件下对小型 ECC 板和大型 ECC 板进行的实验活动，以优化和验证其作为除雪系统的能源效率。
