Proven Solutions for Pavement Longevity

 

Ensuring the performance, safety and durability of our pavement infrastructure depends on effective joint and crack sealing—a vital protective measure against water intrusion, incompressible debris and other harmful elements. Proper joint sealing safeguards structural integrity against environmental and mechanical stresses while extending the lifespan of pavements and other constructions. Recent findings from the Seal/No Seal Group highlight the importance of quality installation as the key factor in sealant effectiveness.


The Seal/No Seal Group was formed to respond to the age-old industry question about the value of sealing concrete pavement joints. Their mission is to develop a committed membership that takes responsibility for determining the long-term effectiveness of sealants in concrete pavements. Three recently published tech briefs by the group address proper joint preparation, the benefits of compression seals and the integration of vacuum systems for cleaning sawed pavement joints. They include:


Proper joint preparation

Consistent results in joint sealing require careful installation practices. Joint preparation is critical for optimal sealant performance. Recommended steps for effective preparation include power washing joints immediately after final sawing, media blasting joint faces followed by air blowing, and visually checking for both cleanliness and moisture to confirm workmanship. A final air blow just before backer rod and sealant installation further supports a quality outcome.


Concrete pavement compression seals

Compression seals offer extended service life and strong durability, making them an effective choice for pavement joints. These preformed elastomeric seals require no heating, mixing or curing, allowing for quicker installation and fewer disruptions. Their design maintains consistent pressure against joint walls, helping keep out water and debris, and withstands UV light, ozone and temperature changes.


The use of vacuums to clean sawed pavement joints

Recent advances in vacuum systems support safer and more efficient joint preparation. These systems help control silica dust and slurry residue during sawing operations, supporting OSHA compliance and creating cleaner joint surfaces for improved sealant performance. Options include wet sawing vacuums with slurry recovery tanks and early entry systems equipped with HEPA filters.
