Crack seal is not a cure all. If the asphalt has so many cracks (sometimes referred to as alligatoring which is a reference to it looking like an alligator’s back) that crack sealing would not be effective, the experts here at Preferred Paving would recommend a remove and replace option or an overlay if possible.
As the seasons change, so does the temperature. In winter, the temperature levels are extremely low, and this causes the asphalt to contract inwards. When the summer arrives, the temperatures are usually high, and this forces the asphalt to expand.
As asphalt contracts and expands based on the season, they form cracks due to the continuous expansion and contraction. If the cracks are not taken care of in due time, they might keep widening and increasing, thus worsening the condition of the paved road.
The most effective solution is using rubberized asphalt. This process involves filling all the cracks that facilitates expansion and contraction as the temperature changes with rubber asphalt.
Crack filling extends the life of the asphalt. The rubberized asphalt that fills the cracks can expand and contract with the temperature, a characteristic that prevents the formation of cracks effectively even as the seasons change. The rubberized asphalt is injected into the cracks using a pressurized nozzle that pushes it securely into the right place.
