MIT Map Relates Fuel Consumption to Paving Stiffness

Greenroads_ER_framedA new pavement-vehicle-interaction (PVI) test developed by the MIT Concrete Sustainability Hub (CSH) provides a tool to measure how much fuel is saved by driving on repaved highways. The PVI test allows researchers to measure the horizontal force required to move a tire forward at different speeds and with different loads. One percent of overall fuel consumption comes from pavement deflection. While a passenger car wouldn’t achieve significant gas savings, road stiffness could make an enormous difference for 40-ton trucks, with up to 4 percent gas mileage savings, according to CSH research.

“If we can save 2 million tons of CO2 per year, at the aggregate level, this becomes extremely important in a low-carbon economy,” says Franz-Joseph Ulm, director of MIT’s Concrete Sustainability Hub (CSH). The industry-funded research center focuses on ways to reduce the material’s 5–10 percent global carbon footprint.

Using the amount of traffic, the temperature of the pavement, structural data, material data, and a map with GPS coordinates, projects could be built that would realize the greatest savings for vehicles where pavement is rough.

PCA Releases 3rd Quarter Oman Report

3rd Qtr Oman Report framed2Oman Report data provides a good indication of the State Departments of Transportation (DOT) paving marketplace, despite having some quarter-to-quarter volatility. According to the latest report from PCA, concrete’s 3rd quarter share of DOT paving volume increased slightly, to 12.3 percent from the prior quarter’s level of 11 percent.  Despite these improvements, the year-to-date 2015 share of 12.8 percent remains below recent trends. 

The lack of adequate federal funds for highways has been an obstacle for higher concrete shares. The new federal transportation bill, the FAST Act, will bring $207 billion to highways over the next five years. While much more is needed to significantly improve America’s deteriorating transportation infrastructure, the funds increase will alleviate much of the uncertainty states have been under regarding their transportation budgets. Ideally, this will lead to more opportunities for concrete pavement projects but do not expect the results to be immediate. PCA anticipates the full effects of FAST will be more apparent in 2017 and 2018.  

Year-end 2015 Oman shares will be available in April.

Meetings

Register for 2016 Spring Congress

Barbour_Haley thumbnail_framedRegistration remains open for the PCA Spring Congress, March 13-15, at the Four Seasons Hotel Chicago. As part of the Spring Congress, a Centennial reception and banquet will be held March 14 at the nearby Renaissance Blackstone Hotel, Crystal Ballroom. This room is where cement executives met in 1916 to form PCA.

In addition to PCA committee sessions and meetings, former Mississippi Governor Haley Barbour will present the Keynote Address on March 14. Ed Sullivan, PCA group vice president and chief economist, will present an economic update on March 15 and the Board of Directors for both PCA and CTLGroup will meet.

Military Should Reconsider Recycled Concrete Bases for Airfields

Poole T Portrait_low_res_framedRecycled concrete as base material for military airfield pavements has never reached its full potential, writes Toy Poole, PhD, M.SAME, and CTLGroup senior principal scientist in a recent Military Engineer article. He says many concrete engineers question the Air Force’s rigorous 2006 restriction on using recycled concrete as a base for airfields. The financial and environmental benefits of recycled concrete, combined with innovative ways to manage these projects, make this change worth a look, Poole says.

Online Library Catalog Provides Free Access to More than 2000 PCA Publications

Construction_Laptop_framedMore than 2000 archival PCA Technical Reports, Promotional Literature, Engineering Bulletins, and Information Sheets were recently added to the PCA Library Online Catalog.  

These PCA publications are fully searchable and full-text downloadable. Search a publication by its Title, Author(s), PCA Keyword (i.e. air content), PCA Publication Code (i.e. EB001), or Abstract. To see all PCA publications currently available in the Library Catalog, simply select the “Publisher” field from the drop-down list and type “PCA” in the search box.

More historical PCA publications will be added to the Library catalog for full-text online access as they are digitized.

Program Spotlights Residential Construction

Houses_that_Work_logo_framedFor some time now, residential construction has been poised for significant growth. To that end, PCA joined the Energy & Environmental Building Alliance (EEBA) as an education partner in 2015, creating a strategic alliance to promote high-performance housing. In particular, EEBA’s Houses that Work™ programs provide a venue for reaching key audiences about concrete technology discussed side-by-side with conventional residential systems within a larger building science context. The programs promote residential construction through topics like moisture management, durability, resilience, and energy efficiency, all areas where concrete materials excel. Targeted primarily to a builder audience, these programs also attract energy raters, code officials, contractors, architects, and engineers. They learn from residential experts about concrete systems, products, and benefits.

Events are scheduled for February 23 in Duluth, Minnesota; February 26 in Twin Falls, Idaho; April 5 in Middletown, Connecticut; April 28 in Squaw Valley, California; and June 9 in Dallas, Texas. More will be scheduled throughout the year.

Abstracts Wanted: PCA Manufacturing Technical Committee at IEEE-IAS/PCA

IEE-IAS-PCA_2016_logoThe next meeting of PCA’s Manufacturing Technical Committee will take place on Monday, May 16, at the IEEE-IAS/PCA Cement Industry Technical Conference at the Gaylord Texan Resort and Convention Center just outside Dallas, Texas. Committee members with a presentation for the steering committee to consider for the meeting should forward an abstract as soon as possible.

At the August 2015 meeting, presentations included: Cement NESHAP: What can cause your dust collectors to be out of compliance? by Andy Winston; PM Compliance Workshop Review: Lessons Learned, Arron Heinerikson; PC NESHAPS: Critical Compliance Concerns, Carrie Yonley; PM NESHAP Challenges, Chris Polizzi; Status of SNCR and SCR, Christa Russell and Bob Schreiber; Managing PM Compliance: Monitoring Parameters and Training, Corinne Fields; and Clinker Cooler Developments, Nathan Murphy.

To register for the conference, please visit www.cementconference.org. Keep in mind that early bird registration for the conference ends March 15 and that registration fees increase $200 after that date.
