Wikipave Post of the Month: Stitching
- Wednesday, 18 October 2017 18:33
This month’s featured Wikipave post covers stitching, the term that applies to two methods used to repair and strengthen concrete at cracks and joints in the pavement. The article includes a brief history of this repair method (which dates to 1971). It also details both cross-stitching and slot-stitching. The article also includes common questions and references.

Concrete Pavements Prominent at SWIFT Conference
- Wednesday, 18 October 2017 10:45
ACPA was among several concrete pavement industry organizations participating in the 2017 Summer Winter Integrated Field Technologies (SWIFT) conference and trade show, held recently in Halifax, Nova Scotia.
Prior to the formal meeting of the Canadian Airfield Pavement Technical Group (CAPTG), a special workshop was held to address, “How to Design Sustainability Into Airfield Pavements.”
Workshop speakers included Gary Mitchell, P.E., ACPA’s Vice President of Airports and Pavement Technology, and Peter Taylor, Ph.D., P.E., Director of the National Concrete Pavement Technology Center, an ACPA technology partner. Mitchell presented on concrete pavement recycling practices and technologies. Taylor presented on the importance of the life-cycle perspective and performance-engineered mixtures.
The formal SWIFT meeting followed the workshop and included moderated discussions and presentations. Industry officials presented on several topics during Tuesday and Wednesday sessions. These included:
- Stringless paving by ACPA’s Mitchell, as well as several ACPA members and technology partners.
- Runway grooving for improved braking performance and directional control by John Roberts, Executive Director of the IGGA/ACPA Concrete Pavement Preservation Partnership and John Depman, P.E., Senior Estimator, Penhall Company.
- Rapid airfield repair using precast by Chris Olidis, P.E., Principal Engineer, Applied Research Associates, an ACPA member.
- Optimized concrete pavement design by Robert Rodden, P.E., Lead Engineer, PNA Construction Technologies, an ACPA member.
Also, moderating the Wednesday technology track was Guillaume Lemieux, Director, Markets and Technical Affairs, Cement Association of Canada, an ACPA affiliate.
SWIFT offers the airport community the opportunity to gather and learn about new pavement design, construction, evaluation and maintenance techniques; materials; chemicals; systems; and equipment available to keep airports safe and operational while addressing any challenges, at minimal cost, during all seasons.

Highway Materials Group Urges Support of Airport Construction Funding Provisions
- Tuesday, 17 October 2017 12:15
As Congress continues efforts to pass an omnibus appropriations bill, the Highway Materials Group* sent letters to appropriations committee leaders to urge them to retain two key airport-related provisions in the FY18 Senate Transportation-HUD Appropriations Bill.
The HMG says the provisions would “dramatically improve aviation infrastructure across the country by modernizing the Passenger Facility Charge (PFC) user fee on originating flights and increasing funding for the Airport Improvement Program (AIP).”
The letters state that ACPA and other national associations whose member provide the construction materials and equipment essential to building America’s roads, highways, and bridges, support these long overdue increases to aviation infrastructure funding that will support critical infrastructure projects for our nation’s airports.
The letters also note that recent infrastructure needs identified by the Airports Council International – North America show airports of all sizes face $100 billion in infrastructure improvements over the next five years. “It is estimated that an additional 9.6 million jobs would be created if projects to meet these infrastructure needs were created – many of which would occur in our sector,” the letters continue. Click on the following links to see the full text of the Senate and House versions of the letters.
* The Highway Materials Group is comprised of the American Coal Ash Association, American Concrete Pavement Association, American Traffic Safety Services Association, Associated of Equipment Distributors, Association of Equipment Manufacturers, Concrete Reinforcing Steel Institute, National Asphalt Pavement Association, National Ready Mixed Concrete Association, National Stone, Sand & Gravel Association, Portland Cement Association, and the Prestressed/Precast Concrete Institute.
