• Joint Adhesive technique
• -Application of specialized
materials to the cold joint surface
• -Seals and protects the low density
area
• -Adheres and flexiblizes the joint

Low Density Zone
-Higher permeability, weaker area
-Increased oxidation/raveling
-Moisture freeze/thaw spalling
-Crack formation, spalling, widening
-Early deterioration
-Significant problem
