Road maintenance materials generally fall into three categories: Cold Patch Asphalt, Bituminous Sealants, and Geotextiles. Cold Patch Asphalt is ideal for emergency pothole repairs in all weather conditions, including rain or snow, as it does not require heating. Bituminous Sealants or Crack Fillers are used for preventative maintenance to stop water infiltration into the road base. For structural reinforcement, Fiberglass Geogrids or Geotextiles are used to prevent reflective cracking in asphalt overlays.
