Research, testing and education have brought many changes to the asphalt maintenance industry. Asphalt Restoration Technology has been rejuvenating Florida since 1993 and is your source for quality performance rejuvenation and preservation. We at AR Tech will help you to protect your property investment and save on frequent repairs and breakdown of your asphalt with Pavement Dressing Conditioner (PDC). Rejuvenation is the choice of property owners, maintenance engineers and association managers that have compared the performance where the rubber meets the road! Unlike traditional sealcoats which merely coat the surface and do nothing to repair or protect the pavement, PDC literally penetrates the asphalt to chemically rejuvenate, revitalize and protect the asphalt by replacing the tars and oils lost due to oxidation. Not only does PDC beautify your property with an even black finish, but also extends the life of your pavement by 3 to 5 years with each application. Pavement Dressing Conditioner: Will not peel, crack, or delaminate like most standard water base sealcoats.
Three Stages of Asphalt Deterioration
Stage I Surface color fades to gray as a result of oxidation and surface oils begin to evaporate. Stage II Fine line cracking occurs along with loss of “fines” (minute crushing material). The surface becomes brittle. Stage III Deterioration accelerates with extended cracking, increasing brittleness and viscosity while reducing flexibility. Contaminates penetrate through crack, further hastening deterioration from below the surface.

Sheflin, J.J.E., “Your Choice: Bad Roads at High Cost or Good Roads at Low Cost”, Paving Forum, Fall 1983 Fluid spills such as motor oil, gasoline and hydraulic fluids are like products to your asphalt and are able to penetrate the surface and destroy the asphalt binders. If left untreated, the aggregate will ravel leaving the spill location soft and unstable to the point that you can penetrate the surface with a knife. By applying PDC, these areas will stabilize and will stop the deterioration.

The sample on the right was protected by PDC; the sample on the left was unprotected. Both samples were immersed in fuel for 24 hours, and then compared for damage. The unprotected sample was visibly damaged, but the PDC protected sample was relatively untouched. |
