项目摘要

Concrete infrastructure are vulnerable to disruptions caused by hydroplaning, ice and snow. The current methods for preventing ice/snow build-up are detrimental to the environment or have been shown to damage infrastructure surfaces, leading to significant maintenance costs and putting society at risk if such damage goes undetected. Infrastructure operators have expressed a strong desire to utilise permeable concrete technology as a means of keeping pavements clear.Permeable concrete pavements drain surface water, enabling storm water to pass through otherwise impermeable infrastructure. However, the frequent maintenance required due to premature clogging, which degrades performance and service life, would be difficult to perform for active infrastructure. Most importantly, conventional permeable concrete pavements have low strength, making them unsuited for infrastructure use. A next generation clogging resistant permeable concrete pavement (CRP, also referred to as Kiacrete) has been developed which is capable of addressing all of these issues. The aim of this PhD project within the Resilient Sustainable Infrastructure Group (https://www.imperial.ac.uk/resilient-sustainable-infrastructure/) is to test the viability and efficiency of incorporating different heating systems in transferring heat through CRP using: i) novel test rigs developed at Imperial College, ii) small and large scale numerical modelling and iii) large-scale field sites at National Green Infrastructure Facility in Newcastle University.

混凝土基础设施容易受到滑水、冰雪造成的破坏。目前用于防止冰/雪堆积的方法对环境有害，或已被证明会损坏基础设施表面，导致显著的维护成本，并且如果这种损坏未被发现，则会使社会处于危险之中。基础设施运营商强烈希望利用透水混凝土技术来保持路面清洁。透水混凝土路面可排出地表水，使雨水能够穿过原本不可渗透的基础设施。然而，由于过早堵塞而需要的频繁维护会降低性能和使用寿命，这对于主动基础设施来说将难以执行。最重要的是，传统的透水混凝土路面强度低，不适合基础设施使用。下一代抗堵塞渗透混凝土路面（CRP，也称为Kiacrete）已经开发出来，它能够解决所有这些问题。弹性可持续基础设施小组（https：//www.imperial.ac.uk/concentr-sustainable-infrastructure/）内的这个博士项目的目的是测试通过CRP传输热量的不同加热系统的可行性和效率：i）帝国理工学院开发的新型测试装置，ii）小型和大型数值建模，iii）纽卡斯尔大学国家绿色基础设施的大型现场。
