When it comes to protecting your asphalt pavements against deterioration. There is no greater value than a correctly applied emulsion. Sealcoating substantially reduces maintenance costs and at the same time extends the life of asphalt pavements by as much as 300%. The cost of sealcoating is truly a minor expense when compared to the cost of pavement replacement.
A few of the benefits of sealcoating:
Appearance
The dark charcoal black color of newly applied pavement sealer improves the appearance of new and old asphalt pavements. Unprotected asphalt surfaces gradually lose their rich black color due to oxidation and weathering. We can preserve the smoothness and resilience of asphalt surfaces and help hide rough spots, small cracks, patches and some surface depressions. Pavements coated with a pavement sealer look cleaner because rainfall washes dirt and debris easily from the smooth, non-porous surface. Traffic lines become more visible.
Stops Oxidation
Actinic rays in sunlight can oxidize the Asphalt oils in pavement, causing brittleness and 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
The intrusion of moisture into asphalt pavement structure accelerates it deterioration and is strongly related to pavement distress. The sealing of well-cured asphalt prevents the seepage of moisture from snow and rain, thus preventing damage from freeze-thaw cycles.
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. Sealcoating 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 prevents the seepage of moisture from snow and rain, thus preventing damage from freeze-thaw cycles.
Protection
We only use the best OVERKOTE sealer that is specifically designed to protect bituminous pavements. It forms a tough, durable and flexible coating that protects asphalt pavements from the damaging elements of weather, water, salts, gas and other petro-chemicals.
Application
Asphalt sealer must be applied to structurally sound pavements by experienced applicators. Asphalt pavement should be protected by two coats; however, the quantities and coverage rates must conform to manufacturer's detailed specifications. Average coverage rates are 0.18 to .20 undiluted gallons per square yard. A latex rubber additive and silica sand may be added for increased traction and durability.

Maintaining asphalt pavement with sealcoat every three years saves an average of $15.25 per square yard or $152,000.00 for a parking lot averaging 10,000 square yards. This translates into more than 48% in savings over unmaintained asphalt.
Parking lot maintenance is most economical when consistently performed from the outset. However, it is never too late to implement a maintenance plan that will optimize your current pavement's condition and prolong its life.

The benefits to consistent parking lot maintenance are clear:
- Protecting your asphalt pavement investment
- Avoiding serious liability issues to tenants, guests and customers
- Beautify the landscape and appearance
- Plus - save more than 48% over unmaintained pavement
Let's talk about Maintenance Savings and a way to free up revenue. Unmaintained (or unsealed) asphalt pavement will likely require repairs after the first two years. Furthermore, this unmaintained surface may require overlay as early as seven years, versus fifteen years for a maintained parking area.
According to a study performed by Girish C. Dubey, chairperson of the Pavement Coatings Technology Center at the University of Nevada at Reno, maintaining asphalt pavement with sealcoat every three years saves an average of $15.25 per square yard or $152,500.00 for a parking lot averaging 10,000 square yards. This translates into more than 48% in savings over unmaintained asphalt. Maintaining asphalt with sealcoat is a small expense that secures nearly 300% increase in asphalt life as well as the aforementioned maintenance cost savings.
Parking lot maintenance is most economical when consistently performed from the outset. However, it is never too late to implement a maintenance plan that will optimize your current pavement's condition and prolong its life.
So how about you save thousands by properly maintaining your asphalt pavement for years to come? It only gets worse with time if not taken care of. Call a pavement expert to find out what you can and should be doing.

A lot of people, I know not you...but many just wait till the asphalt is so damaged that it must be repaired with severe measures. Research and studies prove that you can save approximately half the cost of maintenance on your pavement if you sealcoat consistently from the outset.
The weather is going to be getting warmer soon and it will be time to look at pavement that needs attention. Asphalt repairs can be prevented by a simple pavement maintenance plan and sealcoating the asphalt every few years. Let's talk about sealcoating...but first the problem, then I'll provide the solution.
Asphalt is a combination of many materials composed in a structure that allows for weather elements (such as rain), salts, and other substances to attack and break it down. As the asphalt molecules break down, much of the original benefits - including weatherproofing - are lost. This is first observed visually by the color change in the asphalt surface:from black to brownish gray.
The rate of pavement deterioration depends upon many variables including weather or climate conditions, traffic volumes and frequency of maintenance. After the visual change in color of the asphalt surface, weather, oils and other harmful materials can significantly deteriorate the pavement surface. Oils from vehicle engines, often parked stationary for long periods of time, can cause considerable damage to an unmaintained pavement surface.
Also, further deterioration of unmaintained pavement leads to minor cracks which become wider and deeper without remedy. If these cracks are not remedied, water and other harmful substances will seep into the base and damage the pavement's load bearing capacity, ultimately causing pavement failure. The effects of this are shown in serious alligatoring, rutting, and overall pavement failure. Before long, your parking lot is riddled with cracks, potholes and drainage issues that are seemingly beyond repair.
Unmaintained asphalt shows its deterioration and damage
quickly, in as little as two years, and cracks and potholes quickly develop. Once the cracking forms, lack of proper maintenance will lead to serious liability issues caused by severe potholes and your pavement investment will be in risk of complete failure. The deterioration of unmaintained asphalt happens exponentially faster than maintained asphalt and, consequently, costs much more money over time.
The Remedy/Solution every smart property owner/manager, facility manager, and business owner is doing to keep asphalt repair expenses down to free up revenue.
Sealcoat, specifically refined coal tar, is a mixture of chemicals with a structure that does not allow destructive elements to affect its properties. This material, as a protective coat for asphalt, forms a barrier to protect against weather, salts, oils, and destructive substances that lead to pavement failure. This sealant also restores the asphalt's rich black color, dramatically improving property appearance.
Potential customers' and guests' first impression is your parking lot; a fresh, new appearance will be the best
presentation no matter your industry. By consistently protecting the asphalt pavement from deterioration and from failure, you are prolonging the life of your original asphalt by as much as eight years, or almost double the expected life of an unmaintained pavement surface, without considerable investment in an overlay or other significant remedy.
Parking lot maintenance with sealcoat usually means a three to five year cycle of sealcoating, including crackfill for developing cracks later in the pavement's life cycle, which prolongs the original pavement's life as well as ensuring the appearance of your property.
By evaluating your properties' parking lots on a
necessity basis(or better yet have an pavement expert come check it out free), all parking lot concerns could be easily amortized over three to five years - effectively eliminating your parking lot concerns.
Why go through the need for asphalt repairs every few years when you can sealcoat every few years and save up to half the cost?

How to square a parking lot before layout:
All of your measurements should relate to one line - your base line. Choose the placement of this line carefully. Maybe if you have a long straight curb, you can use this as your base line. If the parking lot serves a building, make sure that the parking spaces will be square and parallel to the building. Once you have a base line, you need to turn a line at 90 degrees to this line. Here's how we do it:
Once you have your base line, go ahead and lay out the ends of the parking spaces. In this case they are all at 9 foot intervals. Select a mark to use as your center mark, count an equal number of marks on either side, and use your long tape to draw an arc roughly at right angles to your base line. Snap a line from your center mark through the point where the arcs intersect. This line will be at 90 degrees from the base line. The longer the lines used, the more accurate the right angle will be.

Increased Loads Accelerate Pavement FailureThe loads imposed by vehicles on parking lots, loading docks, and streets have increased historically both in magnitude and frequency. Weight limits for trucks were increased in the 1980s. Industry efficiencies have
led to an increase in the size of trucks. Truck size and weights have increased as a consequence. With more online shopping and ecommerce comes a rapid increas in trucks and delivery. Freight tonnage in the San Francisco Metro Area is estimated to double by 2030; 72% of this will be carried on trucks, up from 63% today. The region's travel forecast model estimates that between 2000 and 2020, the number of medium and heavy truck trips nearly double. The Port of Oakland is the hub of freight activity for the Bay Area. Arterial streets and parking lots that serve the Bay Area's industrial areas have the highest volume of medium and heavy truck trips today and in the future. Bay Area surface streets carry much of the truck freight that access Port facilities and truck freight terminals. Buses have increased in size and weight in the past two decades and bus trips are also growing at a pace that equals or exceeds the rate of growth in travel demand.
The sum result of these factors is an increased load demand on key freight routes and transit corridors and
accelerated pavement failure. Streets are failing at a faster rate than they did in the past and the requirements for pavement maintenance continues to increase. These trends are being felt world wide and
are due to just-in-time manufacturing, disinvestment in rail and other surface transportation modes. The
factors that influence pavement failure are well documented and need to be recognized in strategies to
address pavement management.
If companies and organizations wait too long to maintain asphalt pavement surfaces, it will cost 2X or 3X more to rehabilitate and reconstruct in the immediate future.
