The condition of Florida roadways is documented through annual surveys conducted by the State Materials Office (SMO) of the Florida Department of Transportation (FDOT). This survey has shown that the majority of the deficient flexible pavements are due to cracking. Based on these circumstances, FDOT's Accelerated Pavement Testing (APT) program has placed a greater focus on deficiencies in the evaluation of crack development and crack resistance. As part of this effort, a computer based program has recently been developed to assist with the identification and quantification of pavement cracks from digital images. A digital camera mounted in front of the wheel carriage on the Heavy Vehicle Simulator (HVS) collects the images at regular intervals during testing to document initiation and the progression of crack development. This paper provides a description of the crack analysis system and offers an example of its use. © 2012 Taylor & Francis Group.
