Hot Applied Crack Sealing
1.01 SCOPE
Crack Sealants to be hot applied are a mixture of materials that form a resilient and adhesive bond capable of effectively sealing joints and cracks in concrete and asphaltic pavements throughout repeated cycles of expansion and contraction. This specification is for such materials and their application.
2.01 MATERIALS
The sealant shall conform to the following ( ASTM D 1190, 3405) and federal specification SS-S 1401C.
2.02 (a) Type 1
A Joint and crack filler manufactured from asphalt and rubber capable of maintaining a seal in moderate climates. ( -18C 50% extension).
2.02 (a) Type 2
A Joint and crack filler manufactured from asphalt and rubber capable of maintaining a seal in most climates . ( -29 C 50% extension).
2.02 (a) Type 3
A Joint and crack filler manufactured from asphalt and rubber capable of maintaining a seal in most climates and in high traffic. ( -29 C 50% extension).
2.02 (a) Type 4
A Joint and crack filler manufactured from asphalt and rubber capable of maintaining a seal in very cold climates . ( -29 C 200% extension).
Physical Requirements:
Maximum heating temperature is the maximum application temperature 210C Requirements as per ASTM D1190 and D3405)
2.03 MIXING
The materials shall be melted in a temperature controlled melting kettle that does not allow the temperature to exceed the maximum heating temperature.
2.04 PLACING
The crack sealer is free flowing at application temperatures. It can be applied by pour pots or pressurized applicator.
Cracks >5mm wide should be routed and blown clear of debris. The crack sealer may be applied by hand with a pouring can or injected with a spray wand.
Cracks <5mm should be swept clean before sealing.
A shoe spreader or similar should be used to smooth the surface of the crack and even the surface. This also removes any excess.
Allow to dry before allowing traffic- 12-24 hrs.
