ACPA Presents at Pavement Workshops

In support, of the Cement Association of Canada, an ACPA affiliate, Eric Ferrebee presented at two workshops last week.  The first was the 2018 Sustainable Roadways Seminar in Red Deer, AB. 

The event, presented by the Cement Association of Canada, in partnership with Concrete Alberta, was focused on concrete pavement design and construction topics, and was presented to an audiencce of provincial and municipal officials, consulting engineers, and contractors.

Eric made two presentations, one on pavement design, including the cement and concrete industries’ PavementDesigner.org concrete pavement design portal, and one on concrete overlays, including ACPA’s National Concrete Overlay Explorer.

The following day, Ferrebee presented at the Industrial Concrete Pavements workshop in Edmonton, AB.  He presented on Industrial Design with ACI’s 330 Guide for Industrial Paving and Flatwork (including jointing and thickness design), as well as PavementDesigner.org

Webinar Covers Pervious Concrete Pavements

The International Society of Concrete Pavements and ACPA will present a 1.5-hour webinar describing the thickness design procedures and construction process for pervious concrete pavements.  The webinar will be presented tomorrow (Thur., Oct. 25) from noon to 1:30 (CDT) and 1:00 to 2:30 (EDT). 

The webinar will cover design considerations and the construction process, including the importance of subgrade, drainage layer and concrete pavement construction, along with how design assumptions are transferred into real life, real time construction steps.  The webinar will also cover how pervious concrete is batched, transported and placed, as well as state-of-the-art developments based on lessons learned from construction projects in the Pacific northwest.

ACPA Presents Airport Pavement Workshop

ACPA last week presented it annual three-day national workshop on best ractices used in the design, construction, and rehabilitation of concrete pavements used for airport applications. 

The workshop program featured technical presentations by subject matter experts with practical experience in the topic areas, including the use of the FAA’s P501 and UFGS 32 13 11 concrete pavement specifications. Leading the discussions were experts from the U.S. Army Corps of Engineer’s Transportation System Center, the Headquarters office of the FAA, ACPA, and companies with direct involvement in FAA and USACE projects.

About  50 people participated in the training and tech transfer event, which was held August 28 through 30 at the Marriott Mission Valley in San Diego.   

PavementDesigner Paper Earn Top Honors

Communication and promotion of PavementDesigner.org has been in full force since its launch in January.  The latest effort by ACPA staff was a paper explaining the ins and outs of the software submitted to the 13th International Symposium on Concrete Roads.   As primary author, Eric Ferrebee was honored with one of two “best” paper honors during the conference held June 19 through 22.  The paper was selected from over 80 submitted worldwide.

“This award is an affirmation of the investment in industry time and resources toward the simple, user friendly, web-based concrete pavement thickness design platform,” said Eric Ferrebee, ACPA Director of Technical Services. “I am proud to be getting the word out and to have been part of the team that worked so hard to launch the project and since to continue improving it.”

PavementDesigner.org was equally funded by ACPA, NRMCA, and PCA, with additional financial support from RCC Pavement Council. ACPA served as the project technical Lead, responsible for migrating existing windows-based design software applications, as well as the overall project manager, prioritizing the software developer’s tasks and managing the project budget.  ACPA also performed coding of certain parts of the application and lead the beta testing phase.  The project was delivered on time and within budget.

In related news, with support from PCA, ACPA has launched the latest round of social media messaging to continue to build awareness for PavementDesigner.org.   The infographics are being posted on Twitter, Facebook & Instagram all week, and intermittently throughout the summer. We invite members, affiliates, and industry allies to join the discussion on Twitter, Facebook & Instagram.

 

Industry Groups Introduce Web-Based Pavement Design Platform

WASHINGTON (January 8, 2018) – Leading cement and concrete organizations[1] today unveiled a new online pavement design tool that offers features and benefits never before available to the pavement design community. 

PavementDesigner.org is free of charge and was created for city, county, and consultant engineers, academia, or anyone involved in design of roadway, industrial, and parking area pavements. PavementDesigner improves upon traditional pavement design software programs, and provides the following value-added features:

  • No cost – The platform and is offered completely free of charge, eliminating the expense and burden of ordering software and updates, licenses, etc.
  • Immediate access – The platform brings the industry’s best pavement design programs[2] together into a single website that allows professionals to design pavements immediately.
  • Cloud storage/retrieval – Users have the option of creating a user ID and password to save their design work, as well as to retrieve projects using any digital device.
  • Automatic updates and improvements – The online system is automatically updated when new content or details are added. Users will not have to download updated software or “patches.”

“ACPA was excited to serve as the project leader for PavementDesigner, working closely with our industry partners and our software designer,” said Eric Ferrebee, EIT, the American Concrete Pavement Association’s Director of Technical Services.  “We are pleased to introduce all in one place the industry’s best design solutions for concrete and cement-based pavement design.  

“PavementDesigner.org represents a dramatic shift in solutions availability to designers of streets, roads, parking lots, and industrial facilities,” he said, adding, “By bringing multiple programs together in one package and eliminating the cost and time to download software, updates, and patches, we have removed barriers and enabled designers to select the best option for pavement designs.”

“This comprehensive but easy-to-use pavement design tool not only covers full-depth concrete, but also provides design solutions for concrete overlays and composite pavements,” said Wayne Adaska, P.E., the Portland Cement Association’s Director of Pavements. “Further, the tool includes other cement-based materials like roller-compacted concrete, cement-treated base and full-depth reclamation with cement.”

Designers also can reach out for design support, using contact information found on the website to reach the network of pavement design experts representing the sponsoring organizations and their affiliates.

 
Using PavementDesigner.org

PavementDesigner guides the user through three basic stages of pavement design.   The user first selects the project type (parking, street, or intermodal facility).  The system then guides the user through the project level details and the design of the pavement structure.  Each module has help screens and conversions built in to assist the user in entering pavement structure details.  After pavement structure information is entered and calculated, the user moves to a summary screen where the pavement design may be reviewed, analyzed, printed, and/or saved. 

“PavementDesigner presents a unique experience to the user which logically steps the designer through the pavement design process,” explained Brian Killingsworth, P.E., the National Ready Mixed Concrete Association’s Executive Vice President of Local Paving. “The user experience and functionality of the website were foremost in our minds throughout the development. Couple that with state-of-the-art technical methods and reporting and the user will find the design process to be exceptional.”


Help is at Hand

The portal also includes helpful resources, which are readily available from the sidebar.  Users can view a PavementDesigner introductory video; view the platform’s map and methodology visual to see solutions and a process flow; and watch a video that shows how to use the portal to design a jointed plain concrete pavement.  

The resource section also includes details from drawings of various concrete pavement structures, as well as images, descriptions, and weblinks to other resources and tools designed to assist pavement designers and others gain more insights about specific types and applications for concrete pavements.  Additional training and support materials will be added as feedback is received.
