Patching & maintenance of carparks using Asphalt
The regular maintenance of asphalt car parks is as important as a solid construction. At some point, we discover that our asphalt car parks are getting bad. We begin to notice cracks on the surfaces, after some time the cracks become potholes. The appearance of cracks on car parks is somewhat natural, but we can reduce the frequency.
The term 'maintenance' describes all the activities done to prevent the quick deterioration of the asphalt car park. Some of the common problems of asphalt car parks include cracks, potholes, structural failures, and ponding. Potholes happen to be the most common fault associated with asphalt car parks. A pothole does not happen overnight; it starts with a crack then becomes a pothole. The most effective way to fix potholes on your asphalt car park is patching.
Patching is the removal of loose portions of asphalt pavements and replacing them with new material. When potholes appear on asphalt car parks, patching is an effective way to curb the deterioration from spreading. The size and depth of cracks and potholes will determine the patching method to use. For car parks with small holes, cold mix patching is an effective technique. The cold mix patch is a temporary fix for your asphalt car park. You apply the liquid asphalt and roll over it with a heavy truck like a bulldozer. If the holes are more prominent, hot mix asphalt is the best material for patching. The hot asphalt mix is preferable for patching. However, when it not available, the cold mix will do the job temporarily.
Cracks, potholes, and other faults are results of activities happening under the surface of the car park paving. These activities are not visible to the human eyes and can take as much as six months before the effects are seen. When patching, proper compaction of the asphalt material is very crucial; it prevents water from entering the pavement. Sometimes, the cause of the crack could be poor compaction during construction.
Although the hot mix asphalt is sufficient, for larger car parks, there is a more effective way of patching. The spray-injection patching technique assures the best patching for your asphalt car park. The principle behind this technique is pressure. Spray-injection patching trucks come with an attached tank containing an emulsion tack coat. It also includes a bin and a pressurized blower. The blower passes compressed air to the cracked part to remove loose asphalt material. The emulsion tack coat is then applied before the aggregate mixed with hot emulsion. Due to the pressure and heat applied during this patching process, there is proper compaction.
