The need for faster and more practical evaluation methods under closely simulated in-service conditions prompted the Florida Department of Transportation (FDOT) to consider Accelerated Pavement Testing (APT). The FDOT APT Program is housed within the new State Materials and Research Park in Gainesville. The Pavement Systems Evaluation Section directs and coordinates all activities associated with the APT Program. A machine known as a Heavy Vehicle Simulator (HVS) is used in this program to subject pavement test tracks to accelerated loads simulating one-half axle truck loading. Generally, APT is defined as a controlled application of a realistic wheel loading to a pavement system simulating long-term, in-service loading conditions. This allows for the monitoring of pavement systems performance and response to accelerated accumulation of damage. APT can produce early, reliable and beneficial results while improving pavement technology and understanding/prediction of pavement systems performance.
