Wednesday Lunch & Learns – Live Webinars with Torti Gallas + Partners

AIAPV has partnered with Torti Gallas + Partners to offer a limited number of slots for live-webinar online-access of the firm's Lunch & Learn CEU events on one Wednesday each month. AIAPV appreciates Torti Gallas' support in enabling the chapter to provide this valuable benefit for the convenience of members unable to get to our educational events in person. 

Permeable Articulating Concrete Blocks (P-ACB) for Stormwater Management

Course Description

Permeable Articulating Concrete Blocks (P-ACB) offers advantage over interlocking concrete pavers as a permeable pavement system. By leaving joints open, these systems have substantially elevated surface infiltration rates and simplified maintenance processes. Because P-ACB systems use thicker blocks and they interlock, the surfaces can be HS-20 rated for heavy traffic—expanding the design possibilities. From a stormwater management and maintenance perspective, it is possible to monitor the water level in the base and document performance and optimize maintenance schedule.

IMPORTANT NOTE: If you attended this webinar provided to our members in September 2021 and again in April 2022, you may attend it again, but will not receive CE credit a second time.

Preapproved Credits: LEED (USGBC), LACES (ASLA), 1 AIA HSW

Learning objectives

After attending this session, participants should be able to:

1. Compare and contrast Articulating Concrete Blocks (ACB) [ASTM D6684] with Interlocking Concrete Pavers [ASTM C936]. Both of these systems support sustainable building by helping to better manage stormwater, because they are permeable pavement surfaces. The presence of open joints, substantially changes the properties of the system.
2. Understand how a P-ACB pavement system can be installed. The ideal process is: 1) Plan out the system, 2) Place and compact the base (including geofabrics) 3) Place the blocks 4) Place and pave asphalt/concrete. Correct installation is critical for its performance as a stormwater best management practice.
3. Understand the expected performance of a P-ACB pavement system as a stormwater best management practice.
4. Understand best practices to maintain a P-ACB pavement system to ensure proper performance over the life of the product as a stormwater best management practice.
