Bold numbers represent inches; metric (mm) shown in parentheses.
Joint opening dimensions (A) are based on minimum and maximum pressures allowed
in ASTM D3542.
Minimum depth dimensions (B) include a 0.25 inch (6mm) recess below the roadway
surface.
|
Other Seals
Delastic® CS & AF preformed seals provide a level top surface
that is particularly suited for pedestrian traffic. Once in the compressed state,
the top sections are much closer together and form a level walking surface and a
pleasing visual effect for exposed vertical applications.
