Permeable Pavement Design

*Open only to Central Ohio Section Members
*Seating is limited to the first 30 people
*Bring your own lunch
*RSVP to brooks.vogel@korda.com by Tuesday, June 24

Purpose and Background
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.

Primary Discussion Topics

• Introduction to porous asphalt, pervious concrete and permeable interlocking concrete pavements
• Live case study that discusses parking lot design and roadway
• Permeable pavement design software

Learning Outcomes

• Understand common design and construction features important to the performance of permeable pavements
• To understand the impact of permeable pavement design features
• Communicate and promote sustainable pavement design and construction

Webinar Benefits

• Understand the key input parameters for the successful design of 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

Intended Audience

• Engineers involved in urban infrastructure design
• Landscape architects
• State DOT and municipal agencies
• Stormwater professionals

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

The Central Ohio Section of ASCE sponsors free continuing education webinars as a service to our members. These webinars are produced by ASCE and normally cost $250 or $300 for ASCE members. However, the Central Ohio Section is paying the registration fee and inviting any interested section members to attend for free. Just RSVP by the deadline. Seating is limited, so do not delay.

You can see the complete list of webinars available from ASCE National on their website. If you see one you like, let us know. If you and your company would like to host one, let us know that too. If you open it up to any interested Central Ohio ASCE section members to come, we will pay the registration fee.
