Resists Fuel Penetration

Resists gas, oil, salt and chemical penetration. Asphalt is a petroleum derivative, soluble in distillates such as gas, jet fuel and oil drippings. prevents damage from distillates and chemicals.

Prevents Water Penetration

The intrusion of moisture into asphalt pavement structure accelerates its deterioration and is strongly related to pavement distress. The sealing of well-cured asphalt with prevents the seepage of moisture from snow and rain, thus preventing damage from freeze-thaw cycles.

Stops Oxidation

Actinic rays in sunlight can oxidize the asphalt oils in pavement, causing brittleness and a resulting loss of aggregates which may rob up to 50% of the original asphalt thickness in just five years. A pavement sealcoated will resist oxidative degradation and retain its value.

Reduces Costs & Increases Value

Crack Sealing

The Pavement Preservation process is all about pavement life cycle costs and extending the life of the pavement at the least cost. Pavement preservation to be
most cost effective must be long lasting. WATER IS THE MOST DESTRUCTIVE element to our pavements. If it rained and snowed everywhere but on our roads and bridges, 90 percent of highway and street work would be eliminated. Since that is not likely to happen any time soon, we need to prevent water intrusion into our pavements. Filling or sealing pavement cracks to prevent water from entering the base and subbase will extend the pavement life. Filling cracks and joints with asphalt materials is not new. These pavement repair techniques have been commonplace practices for decades. The asphalt materials are intended to fill the crack and keep most of the water out of the pavement. When water is kept out, pavement deterioration is slowed.
DURABLE AND ECONOMICAL PAVEMENTS EXPAND and contract with seasonal temperature changes. Consequently, cracks and joints are expanding and contracting when the pavements move. Fillers do not expand or contract. Sealing the cracks with a flexible rubberized asphalt that bonds to the crack walls and moves with the pavement will prevent water intrusion. Sealing is better than filling. Sealing will last longer and cost less. As part of a pavement management system, crack sealing can reduce pavement deterioration by restricting water penetration into underlying base and subbase layers. This restriction helps to maintain pavement structural capacity and limits future degradation. Simply stated, sealing cracks and joints in pavements extends the service life of the surface treatment and the pavement. Crack sealing will not improve initial pavement rideability. The benefits are realized in three to five years when it becomes obvious that the pavement has not deteriorated. In fact, roads that have been crack sealed have better rideability five years later than other surface treatments, such as chip seals, micropaving, thin overlays and slurry seals. In five years these other treatments have come to the end of their life cycle. Roads, driveways, and parking lots that are crack sealed last longer than those that are not. Sealing prior to surface treatments enhances the treatment and further extends the pavement life. Crack sealing stands out as an economical maintenance technique. The overall success of pavement maintenance systems that include crack sealing, combined with the generally low cost, make crack sealing a desired maintenance program. Crack sealing provides the most cost-effective use of dollars over time compared to other pavement maintenance techniques.

Pothole Repair

Why is it important to repair potholes IMMEDIATELY?

Water, either through snow melt or rain, will collect in the pothole, work its way beneath the pavement, and further damage the base and sub-base. Left untreated this damage will creep out from the initial pothole, resulting in broader areas of weak base and broader areas of damage. This “alligatored” pavement, so called because the surface is reminiscent of an alligator's skin, is beyond simple, quick repair. So the longer potholes are left untreated, the more extensive is the damage and the more costly it is to repair. Research from countless studies has demonstrated that it is cost-effective over the long haul to repair potholes as soon as possible. It's important to realize that while potholes can be held to a minimum, they likely cannot be avoided entirely. However a regular maintenance program can help keep the number of potholes to a minimum through timely use of crack repair, patching, seal coating and overlays.
What Causes Potholes?

The main reason potholes form is water works its way beneath the pavement surface
(this is one reason you need to make sure to seal coat your pavement on a regular basis).
Water generally enters into the pavement base or sub-base through cracks—even small cracks. The water moistens and weakens the material beneath the surface, and this material, because it is structurally weaker, can shift when traffic drives over the surface. That's bad enough. But the wet base or sub-base has an even greater effect on the pavement as the temperature changes. As we all know from basic high school science experiments, water expands when it freezes. So this wet material expands slightly as the temperature drops, pushing up the asphalt surface. Then, when the temperature goes up, the base thaws and contracts, leaving a small air pocket just beneath the asphalt. This is known as a freeze-thaw cycle and the more freeze-thaw cycles that occur during a winter, the larger the pocket beneath the asphalt pavement. Eventually traffic driving over the pavement will crumble the asphalt into the pocket, creating a slight depression, and you have the beginnings of a very damaging pothole.

Asphalt Patching

What's the “best” repair?

The question: “What's the best repair” is one we hear often, though probably not often enough. It's a question you should be asking of any contractor bidding to fix your parking lot. But the “best” repair can vary, so it's important to consider all factors when making repair decisions. Through our years in working with property managers we've learned that the most important repair consideration for a property manager is public safety, so the first thing to do is get the hole filled. There are a number of low-cost ways to take care of this and we can recommend the “best” approach to use until you can make the “best” long-term repair. Once the pothole is filled and the immediate problem is taken care of, you can begin to look at the best long-term solution.

What causes asphalt pavement to fail? Inadequate or improperly compacted base materials.

Assuming that the initial asphalt pavement was designed and constructed properly, the primary cause of failure is the penetration of water into the asphalt base.
This process begins with the oxidation of the pavement surface which causes the asphalt to dry and become brittle, this leads to the erosion of the top layer of fine particles and the appearance of larger stones and small cracks on the surface.
If left untreated these cracks grow over time and eventually allow water to penetrate to the base of the pavement.

When water enters the base of the pavement the base material moves and settles leading to further cracking and an "alligator appearance".
When the pavement reaches this stage the only option is removal and replacement of the old asphalt.
