Driveways as they age will eventually become more succeptable to cracking, the most important thing you can do in maintaining your pavement is to have those areas properly cleaned and cracksealed. Here is
The following are the five main types of asphalt cracks you may have on your driveway:
Cracks that occur perpendicular to the direction of your driveway. Transverse cracks generally are caused by changes in temperature and asphalt shrinkage at low temperatures. This type of crack can be effectively crack sealed.
Block cracking begins as the asphalt in driveway ages.The asphalt hardens over time becoming more brittle. As the base material shifts or settles cracks develop. This type of crack can be effectively crack sealed.
Fatigue cracking, or “gatoring” as it’s called because the surface resembles the scaled back of an alligator, is usually due to problems in the base material in the driveway. It is usually considered to be failed asphalt and cracksealing is not repairing as much as delaying the replacement or repaving of that area.
Edge cracks are parallel cracks running along the edges of the driveway, and are usually caused by erosion of the base material at the shoulders of the drive. Cracksealing is more of a temporary solution for edge cracks and generally cannot be a long term repair for this type of crack since the problem stems from lack of material to support to the edge itself.
Spider cracking are small surface cracks in the surface of your driveway, usually results from too much sealer being applied. If a driveway is too coated too thick, or too often. Spider cracks can develop in the sealer itself. These are surface cracks in the sealer and are do to the asphalt settling over time. It is better to avoid this situation alltogher by only applying thin coats of sealer and letting the sealer wear before reapplication.
Cold pour sealants are those that do not require any heating. Cold pour sealers are usually made from acrylic compounds or emulsified asphalt, and come in tubes and sometimes plastic pails. We have tried many different cold pour sealers in the past as they are much easier to apply and less equipment is needed in the application process. We no longer use them. We have found that all the cold pour sealants do not have the temperature range needed to maintain a water tight seal throughout a winter in New England.
Hot rubber sealants must be heated in preparation for application. .The characteristics of the rubber are measured by the elongation point and its flexibility to shift at low temperatures. The hot pour sealant is heated to a temperature of at least 350 degrees Fahrenheit in a melter using a heat transfer oil. Once at the proper temperature the oil is then applied to the pavement surface either pumped by a applicator hose with a wand, or by using a pour pot. We use both application metheods as they each have their own benefits.
Our proceedure for cracksealing driveways
The proceedure for cracksealing is similar to sealing, (usually it is better to seal and crackseal at the same time)
First and most important is to thouroughly clean and prep the driveway surface.
Crackseal all cracks in the driveway and the road seam.
