项目摘要

The broader impact/commercial potential of this I-Corps project is create a new material system of pavements for maintenance saving, safety enhancement, and lifetime extension. The material system can be integrated into a wide range of potential pavement applications from parking lots, to highway ramps, and driveways. The potential customer includes general managers or ground service managers of commercial and residential buildings with large parking lots, officials at the Department of Transportation and Department of Public Works, and even homeowners with driveways. The successful adoption of the technology may result in reducing snow removal costs, reducing parking lots/roads/highways maintenance costs, and lessening accident rates in snowy or icy conditions in winter. The technology may also be used to potentially mitigate pavement distresses due to high temperatures, thereby extending the lifespan of roads and other infrastructure.This I-Corps project is to identify the market and establish the novel pavement technology for commercialization and technology transfer. Inspired by human skin, the proposed asphalt pavement system utilizes solar and geothermal energy to regulate the surface temperature, at which the materials can exhibit the better performance. Asphalt pavements can be damaged or degraded by various weather conditions. To address these challenges, this project develops a multifunctional material system for self-heating and cooling, performance monitoring, self-sensing, and self-healing of asphalt pavements. The system consists of heat exchange loops buried in pavement overlays, which will be heated or cooled using geothermal and solar energy via circulating thermal fluids. The heat collected and stored underground in summer will be used in winter. Carbon nanotube modified foamed asphalt has been developed for better thermal conductivity and strength.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个i-Corps项目的更广泛的影响/商业潜力是创建一种新的路面材料系统，以节省维护、增强安全性和延长使用寿命。该材料系统可以集成到从停车场到高速公路坡道和车道的广泛潜在路面应用中。潜在客户包括有大型停车场的商业和住宅建筑的总经理或地面服务经理，交通部和公共工程部的官员，甚至有车道的房主。该技术的成功采用可能会降低除雪成本，减少停车场/道路/高速公路维护成本，并降低冬季下雪或结冰条件下的事故率。该技术还可用于潜在地缓解高温造成的路面破损，从而延长道路和其他基础设施的使用寿命。这个i-Corps项目旨在确定市场并建立用于商业化和技术转让的新型路面技术。受人类皮肤的启发，提出的沥青路面系统利用太阳能和地热能来调节表面温度，使材料能够表现出更好的性能。沥青路面可能会因各种天气条件而损坏或退化。为了应对这些挑战，该项目开发了一种多功能材料系统，用于沥青路面的自我加热和冷却、性能监测、自我传感和自我修复。该系统由埋在路面覆盖层中的热交换回路组成，这些回路将通过循环的热流体利用地热和太阳能进行加热或冷却。夏天收集并储存在地下的热量将在冬天使用。碳纳米管改性泡沫沥青是为了更好的导热性和强度而开发的。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
