Location
Dunnellon, FL
Application
Airport pavement
Outcome
Improved pavement durability and preventive maintenance performance
PDC was evaluated as a preventive maintenance treatment at Dunnellon Airport in Florida.
According to the Florida Department of Transportation Aviation Office, the project demonstrated PDC’s potential to improve pavement durability, extend pavement life and reduce ongoing maintenance costs.

Testimonials
“Pavements treated with PDC contained a higher penetration and lower viscosity asphalt for 3 years. Pavements treated with Gilsonite contained a lower penetration and higher viscosity asphalt for 3 years. PDC does rejuvenate the old asphalt binder while Gilsonite has a hardening effect on the asphalt binder. It is recommended that the use of rejuvenators be considered a satisfactory maintenance procedure for the upkeep of asphaltic concrete pavements’’.

“In response to your inquiry, please be advised that the City of Pittsburgh’s Public Works Department has used PAVEMENT DRESSING CONDITIONER (PDC) for the past several years with considerable success.
Specifically, we have used the product at Three Rivers Stadium, on the main bus lane through the business district Downtown and currently have spec’d it for use on the bus lane through the university-medical district in the Oakland section of the city.”

“Maintaining existing airport pavements may not only be the best option but, in many cases, the only option. The FDOT Aviation Office expects that PDC could play a major preventative maintenance role, as demonstrated on the Dunnellon Airport, by its ability to improve pavement durability, extend its life, and reduce maintenance costs.”

“The pavement conditioner had apparently been very effective in not only rejuvenating the surface of the asphaltic concrete, but it had caused an alteration in the characteristics of the asphaltic concrete mixture that allowed some sort of rebinding of the crack interfaces.
The effectiveness of the conditioner is far in excess of the expectations placed upon it by the District Ill personnel and research personnel involved”

“The increased surface performance attained by the application of PDC materials on the pavements, in our professional opinion, has resulted in a rejuvenated pavement surface”
“Treated asphalt material properties show on overall improvement in performance as compared to test results performed on untreated companion samples”
“The surface material property improvements obtained with PDC treatments is contrary to test results normally obtained from testing of pavement materials surfaced with Gilsonite and/or untreated coal tar materials”
