TRAINING.

Overview

After participating in this course, you will be able to:

• Understand the essential design and construction features that contribute to the long-term performance of permeable pavements.
• Analyze the impact of permeable pavement design elements on both hydrological and structural performance.
• Communicate and advocate for sustainable pavement solutions that promote stormwater management and environmental resilience.
• Identify potential risks and common issues in permeable pavement design and construction, allowing you to mitigate failure factors.
• Apply design tools and methodologies to create robust permeable pavement systems tailored for municipal and parking area applications.

Description
Storm water management is a key component of urban infrastructure design. Numerous agencies throughout the United States and Canada include permeable pavements as a key component of best management practices for stormwater management.

If properly designed and constructed, permeable pavements can help rainwater infiltrate soil, decrease urban heating, replenish groundwater and reduce overall storm water runoff. The construction of permeable pavement systems that can accommodate surface water runoff is gaining increasing attention through the Leadership in Energy and Environmental Design (LEED) program.

In a 1999 stormwater technology fact sheet on porous pavements, the U.S. Environmental Protection Agency (EPA) indicated that porous pavements traditionally have a failure rate of over 75 percent. Generally, failure is attributed to poor design, inadequate construction quality, improper treatment of the subgrade soils, and overloading of under designed pavements. Recent studies in the United States, United Kingdom, and Australia have shown the significant benefits of permeable pavements.

This webinar provides background on the key features of permeable asphalt, concrete and interlocking concrete block pavements along with guidance, design tools and methodologies to assist in designing pavements to accommodate hydrological and structural pavement design for municipal and parking area permeable pavements and compare equivalent structural designs.

Syllabus

Webinar Benefits

• Understand the key input parameters for successfully designing permeable asphalt, concrete and interlocking concrete block pavements.
• Ability to design a permeable pavement for both structural and hydrologic capacity.
• Utilize previously impervious infrastructure to reduce the impact of peak stormwater runoff and improve stormwater quality.

Webinar Outline

• Subgrade preparation
• Characterization of design traffic
• Base and subbase materials
• Design details for structural capacity
• Design details for hydrological capacity

A live case study follows the presentation, discussing the design of a parking lot and a roadway using a software application developed specifically for permeable pavement design. Design details include:

• Determination of design traffic
• Analysis of subgrade support capability
• Analysis of rainfall intensity
• Site drainage analysis
• Appropriate selection of base and subbase aggregates
• Supplementary pavement surface and subsurface drainage
