Permeable interlocking concrete pavers (PICP) are a sustainable pavement system for on-site infiltration and treatment of stormwater. As an alternative product to traditional asphalt pavements PICP is an important technology that can help reduce urban flooding and pollution. As a pavement and stormwater system PICP requires different operational and maintenance practices than traditional impermeable pavements. In Canada, the adoption of PICP for commercial, institutional and residential application is significantly hindered by a lack of proven operational practices and maintenance solutions to support long term functionality of the pavement. This project brings together three industrial partners and one regulatory body. Partners include the Interlocking Concrete Pavement Institute (ICPI), Brampton Brick, Lafarge Canada and the Toronto and Region Conservation Authority (TRCA). The proposed research will investigate promising best management practices for two operational scenarios: (1) winter operations and (2) hydraulic rejuvenation. During the winter melted snow and ice on a PICP surface infiltrates to underlying subbase preventing black ice from forming on the surface. As a result, PICP surface will require different (and possibly less) de-icing application rates than conventional asphalt. This study will test this hypothesis and determine the type and amount of de-icing/anti-icing required for a typical PICP pavement. Over the years a PICP surface loses infiltration capacity as sediments accumulate clogging the pavement surface. Current recommended maintenance practices by industry (vacuum sweeping) are not practical for most PICP owners and do not provide an acceptable level of restoration. If left unadressed, the lack of feasible and effective maintenance options will likely prevent the use of PICP for stormwater management in Canadian communities. The second half of this study will test the effectiveness of pre-treatment practices to maximize hydraulic rejuvenation. The goal of this work is to develop customized operational and maintenance best management practices (BMPs) for the PICP industry in Canada.

透水互锁混凝土摊铺机（PICP）是一种可持续的路面系统，用于现场渗透和处理雨水。PICP作为传统沥青路面的替代产品，是一项有助于减少城市洪水和污染的重要技术。作为路面和雨水系统，PICP与传统的不透水路面相比，需要不同的操作和维护方法。在加拿大，由于缺乏成熟的操作实践和维护解决方案来支持路面的长期功能，PICP在商业、机构和住宅应用中的采用受到了很大的阻碍。该项目汇集了三个工业合作伙伴和一个监管机构。合作伙伴包括Interlocking Concrete Pavement Institute （ICPI）、Brampton Brick、Lafarge Canada和Toronto and Region Conservation Authority （TRCA）。拟议的研究将探讨两种作业方案的最佳管理实践：(1)冬季作业和(2)水力恢复。在冬季，PICP表面融化的冰雪渗透到下垫基，防止在表面形成黑冰。因此，与传统沥青相比，PICP表面需要不同（可能更少）的除冰率。本研究将检验这一假设，并确定典型PICP路面所需除冰/防冰的类型和数量。多年来，由于沉积物堆积堵塞路面，PICP表面失去了渗透能力。目前行业推荐的维护方法（真空清扫）对大多数PICP业主来说是不实用的，也不能提供可接受的修复水平。如果不加以解决，缺乏可行和有效的维护选择可能会阻碍PICP在加拿大社区进行雨水管理。本研究的后半部分将测试预处理实践的有效性，以最大限度地提高水力再生。这项工作的目标是为加拿大PICP行业开发定制的运营和维护最佳管理实践（bmp）。
