The concrete pavement industry has developed the Wipe Test to provide contractors and inspectors with a new tool for ensuring consistent, high-quality levels of joint preparation and cleaning prior to the installation of sealant materials.   The Wipe Test is intended as a quality control sampling test.  For a copy of this document, click  RTU 17.01-2017.  ACPA/National has also developed an accompanying joint sealing technical document, click TB010-2018 to review and download.


The National Concrete Pavement Technology Center (CP Tech Center) at Iowa State University is a national hub for concrete pavement research and technology transfer. The Center was founded in 2000 and has been instrumental in developing and helping to advance the nation’s strategic plan for concrete pavement research, the Concrete Pavement Road Map.

With federal, state, and industry support, the National CP Tech Center helps set and implement a national research agenda that seeks to benefit the concrete paving community.

The center accomplishes this work by facilitating strategic short- and long-term partnerships. Its partnering relationships include almost 100 organizations in more than 30 states—including the Federal Highway Administration, state DOTs, state concrete paving chapters and associations, industry representatives, and research universities.   Visit the CP Tech Center for more information.



The National Concrete Consortium (NCC) is comprised of academia, government agencies, and industry working together to continuously improve concrete performance and durability in a cost-effective manner.  The NCC provides an ongoing national forum for portland cement concrete (PCC) and pavement technology sharing to encourage uniform specifications, mutual problem solving, coordinated research, implementation of new technologies and to promote quality design and construction practices.

The NCC meets semi-annually and includes representatives from approximately thirty state highway agencies. PennDOT is represented on the NCC by Neal Fannin, P.E., Pavement Materials Engineer.
