Asphalt Crack & Joint Sealing (Rubberized Hot Applied)
The primary preventive barrier stopping sub-base water intrusion and reflective cracking.
Technical Overview & Method Purpose
Asphalt crack sealing is widely recognized by highway authorities worldwide as the single most cost-effective pavement maintenance procedure. In the UAE climate, road surfaces experience extreme diurnal temperature cycling between scorching daytime heat and cool desert nights. Without an elastomeric seal, water and non-compressible sand enter open cracks, rapidly destroying base-course compaction and causing severe potholes and reflective cracking.
Engineering Specifications
Executed using genuine Crafco polymer sealants and hot melters with full compliance certification for RTA, MoEI, and municipality tenders.

High-Pressure Hot Compressed Air Lance Blasting: Vaporizes all residual moisture and expels dust, sand, and loose debris at 1000°C velocity.
Precision Pavement Routing: Utilizing Crafco Model 200 routers to cut a uniform reservoir (standard 19mm x 19mm or 12mm x 12mm) along the crack path, ensuring optimal expansion and contraction geometry.
Hot-Pour Sealant Application: Premium Crafco polymer-modified rubberized asphalt sealant is heated to 190°C–200°C in oil-jacketed melters and pressure-injected into the prepared reservoir.
Flush or Overband Profiling: Finished with specialized squeegees for a flush or low-profile overband that immediately withstands high-speed traffic without tracking.
