Technical Information





In 2009, the Seal/No Seal Group accomplished the following, using its limited funding, with the assistance of many dedicated industry volunteers: 

  • 58 of the 93 original FHWA Test Sections were re-evaluated in 2009, extending the initial performance period approximately 40% over the original FHWA “Effectiveness of Sealing Transverse Contraction Joints in Concrete Pavements” Study
  • Four state DOTs conducted evaluations of their test sections
  • Ten new sealant test sections were constructed in 2009
  • Initiated a study to determine the effect of joint sealant or lack thereof on moisture infiltration/base
    erosion and its potential environmental impact; developing an infiltration test to qualify the joint seal
    condition - Tests occurring at the Riverside Campus of Texas A&M University, in conjunction with the Texas
    Transportation Institute


The Seal/No Seal Group recommends methods for determining sealant effectiveness. The following is a suggested program for any potential agency, municipality, or company to use if they believe the seal/no seal issue needs to be looked at in their area.

Current FHWA sealant test locations throughout the United States.
