Premium Isn’t Just for Gas……
Pavement Maintenance Magazine May 2018, Nick Howell (13-year member of the Pavement Advisory Board) “Premium Sealers have been around for decades, it appears they are becoming more popular now. Most major brands offer a premium version of sealer, but just like premium gasoline – get ready to pay. I’m a believer that as contractors we shouldn’t have a race towards the bottom. Next, follow the manufactures specifications for sealcoats. Normal sealcoats call for two good coats, however, you may opt for a third coat in those high traffic areas.’
The 2017-2018 the sealcoating industry lost 55% of their market share since larger commercial property owners became dissatisfied with the aesthetics and the ineffective results of the sealcoat, coal tar, or asphalt sealer. I am convinced that a race to the bottom is exactly what lead to the seal coating industry’s loss of market share. There are honest contractors out there doing it right. However, they are far outnumbered by the contractors who will tell you they have the best price! Unfortunately, you will wind up with a watered down one coat surface coating, that might only last 6 months to a year.
Rejuvenators: My company started using a penetrating coal tar/sealer rejuvenator 30 years ago and eliminated all the problems associated with emulsion (water base) coal tar and asphalt sealers. Whether CPR is used on a FAA airport runway, your condominium or shopping center, the material specifications are the same. CPR has also been found to be very competitive in price to a seal coat when both are applied to manufactures specification.
All Rejuvenators Are Not the Same – The first two-part rejuvenator was manufactured by a coal tar emulsion seal coating company about 20 years ago. The company had to increase the percentages of solvent used, which changed the dynamics of the rejuvenator, due to the inadequate amount of tar oil to rejuvenator. This resulted in the increase of insoluble carbon solids by 40% into the 17 to 22 range. The balance of the higher carbon solids now remains on the surface of the pavement, the same carbon solids that are plaguing the coal tar emulsion industry.
CPR (Conditioning Pavement Rejuvenator), unlike emulsion sealcoats, is in the pavement not on it, with only a small amount of carbon solids (5%) remaining on the surface of the pavement. CPR is a three-component product and has approximately 4 times less carbon solids that are contained in a two-part rejuvenator. CPR provides greater and deeper penetration and replaces the evaporated asphalt oils from the oxidized pavement.
Why Asphalt Pavements Deteriorate – Asphalt deterioration is a chemical as well as a physical process. It is the chemical aspect that people fail to recognize when planning a pavement maintenance program. The exposure of the UV rays from the sun is devastating to your pavement. Oxidation chemically alters the asphalt binder, which is glue that holds the mix of sand and stone together. This oxidation effect makes the binder hard and brittle and prone to raveling (releasing of stone and sand). The surface becomes rough, raveling occurs and cracks form.
CPR Rejuvenator replaces the asphalt’s oils lot through oxidation. CPR penetrates down into the pavement 3/8 inch to 1/2 inch, which improves the actual condition of the asphalt. CPR stops the raveling, keeps the pavement flexible and provides superior fuel resistance. CPR has been extensively tested by the Army Corp of Engineers along with various state agencies. CPR meets the FAA’s latest P-632 specification.
CPR Contractors, Property Managers and Owners should be working together to help save our precious resources and environment by recognizing the importance of modern pavement technology. CPR’S most recent air quality test results were shown to have “0” parts/million. Visit the PRT-GROUP.COM, for more information and test results.
