Concrete pavers are a popular hardscaping product as they create attractive surfaces and are long-lasting. Increasingly pavers are being used for more than just aesthetics but are design to be permeable and allow for rainwater to infiltrate into underlying soils. Permeable interlocking concrete pavers (PICP) are an on-site engineered stormwater management system. Site level stormwater management controls can mitigate flooding risks by restoring naturalized processes such as infiltration and providing distributed storage of stormwater. In order to ensure the long-term functionality of PICP there is a need to address installer related issues and to develop well defined standards and guidelines. Over time PICP losses its ability to infiltrate stormwater as surface openings gradually become clogged with sediment. Cost effective maintenance practices to rejuvenate surface infiltration capacity still need to be developed. In this project the Canada Masonry Design Centre will convert 175 sqm of existing walkways to PICP. The experimental pavement will be used to investigate the the impact of stormwater detention time for PICP on quantity control of stormwater, water quality concerns from the 'first flush' after construction as well as performance in the first winter after construction. Three detention practices will be tested: (1) free release, (2) twenty-four hour detention, (3) forty-eight hour detention. Results of this research will be integrated into draft installation and operation standards to be developed by CMDC.

混凝土摊铺机是一种受欢迎的硬景观产品，因为它们创造了有吸引力的表面和持久。 越来越多的铺路机被用于不仅仅是美学，但设计是渗透性的，并允许 雨水渗入下层土壤。渗透联锁混凝土摊铺机（PICP）是一个现场 工程雨水管理系统。现场水平的雨水管理控制可以减轻洪水 通过恢复自然化过程，如渗透和提供分布式雨水储存，减少风险。在 为了确保PICP的长期功能，需要解决与安装程序相关的问题， 制定明确的标准和准则。随着时间的推移，PICP失去了渗透雨水的能力， 表面开口逐渐被沉积物堵塞。成本效益的保养方法，以振兴 仍需开发地表渗透能力。在这个项目中，加拿大Massimo设计中心将 将175平方米的现有人行道转换为PICP。试验路面将被用来调查 PICP雨水滞留时间对雨水量控制影响， 施工后的“首冲”以及施工后第一个冬天的表现。三个拘留 将检验以下做法：（1）自由释放，（2）24小时拘留，（3）48小时拘留。结果 这项研究的成果将被纳入CMDC制定的安装和操作标准草案。
