Seal or No Seal? That is the Question

There is a great deal of debate over whether or not to seal sawed concrete expansion joints. The seals require maintenance over time. Many road agencies believe it is necessary to seal all joints to keep water and debris out. However, some engineers do not believe that all applications of seals are cost-effective. In 1990, the Wisconsin Department of Transportation (WisDOT) stopped sealing portland cement concrete (PCC) joints. WisDOT had studied the effect of sealing PCC on pavement performance and concluded that pavement with unsealed joints had better performance and saved on costs. Continued debate on the subject led to the forming of the Seal/No Seal Group, which works to do research and provide information that can help road agencies make a decision.
