The accumulation of snowfall and ice can pose physical and health hazards to home residents. Shoveling snow can also be hazardous and even fatal among both adults and children. Heated driveway systems, also called snowmelt systems, are a technological alternative to shoveling, salting, and other snow removal methods. Current snowmelt systems suffer from high costs of materials and installation, and poor efficiency. The industrial partner is currently developing a novel heating system based on conductive polyurethane-cement composites as a retrofit for snowmelt applications. Such a system will require much less material, higher heat transfer efficiency and has the advantage of eliminating the expensive reconstruction required for embedded systems that need to be installed below the paved surface. This in turn will reduce the costs of installation and

降雪和冰的积累会对家庭居民的身体和健康造成危害。铲雪对成人和儿童来说都是危险的，甚至是致命的。加热车道系统，也称为融雪系统，是一种技术替代铲雪，盐和其他除雪方法。目前的融雪系统存在材料和安装成本高、效率低的问题。工业合作伙伴目前正在开发一种基于导电聚氨酯-水泥复合材料的新型加热系统，作为融雪应用的改造。这样的系统将需要更少的材料，更高的传热效率，并且具有消除需要安装在铺设表面以下的嵌入式系统所需的昂贵重建的优点。这反过来又会降低安装和安装的成本
