Asphalt is typically the most durable material option for all types of pavements, especially those leading to your garage. Over time, however, the material will distress as the impact of foot and vehicular traffic take a toll on it. If you do not carry out routine maintenance, the distress in your asphalt will be compounded into gaping potholes which over time become craters. Most people aiming to save money will opt for concrete and other paving materials to fill up the pothole on their asphalt.
Professional asphalt repair is, however, the only option for repairing potholes and asphalt in many Sandy, Utah properties. Patching is the ideal choice for strengthening the weak spots in your asphalt and covering the potholes. Many experts use different techniques used for the patching of asphalt pavements, and here are some of these techniques.
Throw and Roll Repair
This is a basic asphalt repair method in which liquid asphalt will be filled into the potholes then rolled over and start solidifying on reaction with the air. Throw and roll repair is generally done in adverse weather conditions like winter when you need an ‘emergency patch’ as you await a permanent repair solution in optimal weather. This repair method is inexpensive and requires minimal labor. The failure rate of the throw and roll repair technique is however high, and its cost might be five times over the cost of other methods.
Semi-Permanent Repair
This is a long lasting solution for issues in asphalt surfaces compared to the throw and roll method. Here, the surface is prepared through the removal of debris and water using an air compressor. Afterwards, the pothole is cut back using power equipment or hand tools, and a patching mix is filled in the hole and compacted with vibratory rollers. Semi-permanent repair is generally carried out in warm months when the mix will dry out fast.
Spray Injection Repair
This uses a truck-mounted machine for the blowing out of the water and debris in your potholes. After this, emulsion and aggregate are injected into the pothole at high pressure, and hence no impaction will be needed after this. Spray injection repair is ideal in adverse conditions. This is the preferred method over the throw and roll method in winter since it also dries fast and is more durable compared to the latter.
Infrared Thermal Patching
Here, a panel will be used to heat the damaged asphalt surface to a set temperature. The heat will penetrate the asphalt to approximately 3 to 4 inches. After the old asphalt is removed and new hot mix asphalt is raked into the pothole, a roller is used to compact the repaired area. The primary advantage of this repair technique is its ability to match other areas on your asphalt surface and the minimal time it takes. Though costly, infrared thermal patching will leave your asphalt looking new.
Potholes in your asphalt will not only be its weak point but can also cause grave injuries as they trip pedestrians and might damage the vehicles which use the pavement. Their expert patching using the above methods will hence avert costly litigations for personal injuries for your company. Moreover, patching will make your pavement more durable.
