Some state governments are still fighting potholes via traditional "throw and go" asphalt repair methods, upping budgets each year to cover the rising number. However, the Louisiana Department of Transportation and Development has looked into long-term solutions to pothole problems. One material they have qualified for pothole repair is based on a relatively new technology called Permafill, which comprises a functional copolymer-based filling material. Permafill is used in holes that form around metal joints to repair and protect the joint from long-term damage. It also has been used on major concrete roads, such as Interstate 10 (I-10) and I-55 in Louisiana. Potholes filled with the substance 3 and 4 years ago are still holding up in the Bayou. These potholes may never have to be refilled because the patch will last for the lifetime of the road. Early test patches in Texas so far have lasted 9 years. Although initially more expensive than the throw and go method, its durability can produce significant cost savings.
