Hot rubber crack filling:
- Use MDOT SPEC 3405 hot applied material.
- Cracks are power cleaned and all loose debris will be removed using high powered blowers and steel wire bristle brooms.
- Deep cracks are pre-filled with silica sand to prevent sinking as needed.
- MDOT spec material is applied to cracks using a banded method (1/2” on either side of the crack) to prevent water from sitting on or near the crack.
*Hot rubber crack filler is for major cracks of approx. 3/4” wide and smaller only. This material is not meant to seal broken areas, edge cracking, hairline cracks, raised cracks and cracks over 1.5” wide. Filling the gap or crack between any concrete and asphalt is not part of this process
