Concrete pavement compression seals, manufactured ready for installation and crafted primarily from polychloroprene (Neoprene), eliminate the need for field heating, mixing or curing—showcasing exceptional resistance to environmental and mechanical stresses. A standout innovation is the six-cell cross-braced design that emerged in the mid-1990s, which optimally balances movement capability and
compressive force to ensure a lasting, watertight seal.
What sets these seals apart is their ability to minimize sliver spalls, a common challenge with liquid sealants, while delivering unmatched durability even under extreme conditions. The use of neoprene-based lubricants and adhesives further enhances their effectiveness, seamlessly bonding to surface irregularities for superior performance.
Compression seals are known for their long service life. This is why AASHTO’s PaveME pavement design
software indicates that compression seals are the only sealants that extend pavement performance.
Dive into the full tech brief here for a deeper look at concrete pavement compression seals, their original
design criteria and their critical role in advancing concrete pavement durability and performance.
