During colder months we use a product called cold mix that remains pliable in winter temperatures. When the materials become available in warmer months, we use a product called hot mix asphalt, which leads to a more permanent repair.
To report a pothole on Baltimore County roads, call 410-887-3560, or report a pothole online. When we receive a request for repairs, it is forwarded to one of eleven Highways shops located throughout the County. Normally our crews will be able to make repairs to the pothole within 48 hours. |
