Pot hole repair
Potholes are a potential hazard to drivers and vehicles on the roads. A pothole can be identified when the asphalt surface has been found broken up due to localised distress in the pavement surface and the base course. Due to the effects of the elements and constant traffic, pieces of asphalt get disturbed by the action of the vehicles resulting in formation of a bowl type structure.To be classified as a high severity pothole, this structure should have a minimum depth of six inches.
Most people and road crews are not aware about the correct way to repair a pothole. With proper selection of materials and their application, pothole repair longevity can be increased and driving frustrations greatly reduced. Correctly patching up the potholes, therefore, is extremely important to avoid long term expenditure that is associated with this type of work. Pothole repair can be of two types, either for Emergency or temporary repair work or a Planned repair program.
Pot Hole Repair
Temporary repair work
This basic pothole repair work involves placing of all the asphalt patch materials into the damaged portion and roll it by driving a heavy vehicle over it.This method is not long lasting and should be adopted only in emergencies.
Semi-permanent pothole repair
This is an ideal way to deal with pothole hazards and is considered best next only to a full time road replacement.Clean the pothole carefully by removing the water and debris from it and then put deep clean cuts along the sides of the hole.The reason to do this is to essentially provide a sound base for the new hole. Then place the patch mix material in the trimmed hole and compact the repaired portion with a vibratory roller which should preferably be of a size smaller than the area of the patch.
Pothole repair by spray-injection
This is another semi-permanent way to treat a pothole, though, it requires specialized equipment to carry out the work. At first all the debris and water should be removed from the pothole. The by use of a spray, apply a tack coat of binder all around the hole, followed by blowing aggregate and asphalt into the pothole. Then simply cover the repaired patch with a layer of aggregate. No compaction is necessary after this.
Edge seal pothole repair
First fill the pothole with the asphalt repair mix and compact it with any roller or heavy vehicle.Then provide a ribbon of tack material by the edges of the hole, so as to overlap the patch and pavement. Place sand on the asphalt tack to avoid tracking by the passing vehicles.
Permanent pothole replacement
This best way to repair potholes is complex and needs to be done by professionals. It essentially involves replacing worn out asphalt with new asphalt and providing an entirely new pavement. This new surface can either be of asphalt or concrete.
