Abstract:

Profilographs are widely used for characterization, specification, and quality control of initial pavement roughness during highway construction. Pavement roughness is indicated by a profile index (PI). The PI is usually evaluated manually from the profilogram, which is a strip chart of profile traces, using a blanking band profile index (BBPI) algorithm. The manual BBPI algorithm is laborious, subjective, and prone to operator errors; thus results are highly unreliable and unrepeatable. A new personal computer software package, APPARE (automated pavement profile analysis and roughness evaluation), currently being developed at the Louisiana State University using the profilogram and other types of digitized pavement profile data, is reported. APPARE has an interactive graphical user interface and an image-processing engine capable of digitizing profilograms using commercially available, low-cost desktop scanners; it evaluates the PI and other widely used roughness indexes, such as international roughness index, using digitized pavement profile data from any profiling and roughness measuring instrument. In particular, a fine-tuned computer BBPI algorithm is developed and successfully implemented.
