Maintain your asphalt! Left untreated, asphalt pavement will deteriorate rapidly. The asphalt binder that holds the pavement together begins to oxidize and weather soon after installation. Moisture penetrates the asphalt, causing further damage and deterioration to the pavement.

One of the major ways moisture penetrates asphalt is through fatigue cracking. Fatigue cracking occurs in areas subjected to repeat traffic loadings (wheel paths), characteristically with a chicken wire/alligator pattern in later stages. This cracking allows water into the pavement, which slowly breaks it down and eventually forms a pothole. Potholes are bowl-shaped holes of various sizes in the pavement surface. The best fix for heavily cracked areas and potholes is to replace that area of asphalt.

Do not wait to fix potholes and other areas with cracking! These areas of damaged asphalt can easily double within a one-year period. When problem areas arise, Walker-Moody can patch and crack fill these areas to extend the life of your pavement. Once moisture is prevented from penetrating the asphalt, this is also an ideal time to sealcoat the surface and prevent de-raveling (scattered loose rocks).


The best fix for fatigue cracking and potholes is a hot asphalt patch. For areas with fatigue cracking, you will need to cut the asphalt out. Cut enough asphalt so that the hole is about 2 inches deep. Clean the patch area so that all loose debris is removed. You will have to spray tack coat in the patch area and around the edges; this acts like a glue and binds the hot asphalt to the current surface. Lastly, place the hot asphalt in the hole and compact.

Sometimes the cracking hasn’t damaged the asphalt enough to warrant a hot patch. A cheaper solution to remove and replace it is crack filling, which starts with cleaning the loose debris and making sure it is dry. Apply a hot crack filler, such as CrackMaster PL (flexible parking lot formula), and open the area for vehicular traffic within five minutes.
