Since crack sealing is a preventative maintenance measure, the type of cracking is a major determinant of how, or if, cracks or crevices can, or should, be sealed properly. Of course, the most to be sealed, but once again, as mentioned earlier, if the crack is due to structural failure, methods of repair/replacement, it will prove most beneficial.
To get the best results, it would be better to call for a pavement contractor in Harrisburg. There are several methods that are used by paving contractors.
One of the most effective methods, and therefore most often used, is hot rubber Cracksealing. Compared with a cold applied sealer which usually only lasts 1-2 years, a hot rubber crack sealer has a life cycle of 3-5 years. A process that has been shown to apply hot rubber crack sealer described below.
Step 1: Cleaning and Drying
To help ensure the correct sealant adhere to the surface, cracks must be clean and dry – free from dirt, dust, broken asphalt, oil, and humidity. Achieved by both routing and/or hot-air-lancing.
Step 2: Sizing it Up
Routing and hot air-lancing are not only clean and dry cracked, but they also help to achieve the optimum width to depth ratio. A 1 "to 1" ratio is optimal.
Step 3: Heating Sealer
Since different brands of sealers will be used depending on the unique characteristics of the different projects, the paving contractor will apply a hot rubber crack sealer in accordance with the guidelines of the plant.
Step 4: Apply Sealer
Now it is heated, hot rubber crack sealer material must be applied immediately after the cracks cleaned and dried. To do so will require cleaning and drying done again.
