AASHTO PP 67-16 PDF Download

The AASHTO PP 67-16 standard provides guidelines for quantifying cracking distress in asphalt pavement surfaces using automated methods. The standard does not specify the equipment, instruments, or software to be used, but states that any equipment that meets the functionality requirements can be used.

The goal of this standard is to standardize the quantification process and ensure consistent pavement condition estimates while still allowing for innovation. The level of automation covered by this standard involves minimal human intervention, although human review is still required for quality control and assurance, as well as to detect and correct any outliers in the automated results.

The standard also recommends collecting pavement images according to AASHTO PP 68 and suggests sampling the images from the collected data based on agency requirements. The sample size and spacing should be determined based on factors such as construction practices and pavement continuity, with a recommendation of using a 100 percent sample until a statistical analysis-supported sampling method can be established.
