Crack sealing is an extremely economical way of maintaining pavements, and a necessary process that can greatly extend the life of asphalt pavement surfaces when applied properly.
Cracks in asphalt surfaces allow water to penetrate the surface, which softens the stone base and can lead to spider web style cracks, pot holes and other forms of degradation.
If not treated, these cracks will allow rain and moisture to flow through pavement and erode base materials; which will result in potholes, and ultimately in premature failure.
Patching may not last and can cost much more than a maintenance routine of crack-sealing. When it comes to crack sealing, an ounce of prevention is worth several tons of cure.
Crack repair basics
Only a knowledgeable and experienced asphalt contractor should be hired to evaluate, plan and carry out needed crack repairs. Trust CAM service to evaluate the methods and proper materials for each asphalt pavement repair.
Multiple factors should be considered before beginning to fill cracks in asphalt pavement. We will evaluate the overall condition of the asphalt pavement, but we will also consider weather conditions, including the moisture, humidity and temperature. We must also consider the nature of the crack, and whether it has stopped expanding or is actively growing. This initial evaluation helps us determine the exact procedure and materials used to fill the cracks.
The cracks will need to be as clean and dry as possible to ensure proper adhesion of the crack filling material. Any moisture present in the cracks must be removed as well as any dirt and/or debris. This includes, but is not limited to any vegetation that might have begin to growing in the cracks, loose particles of asphalt, dirt, dust and rocks. The fill material needs to be used exactly as indicated by the manufacturer to ensure the integrity and longevity of the repair.
