Full Description
AASHTO PP 80-20 shall consist of continuous thermal profiling of the asphalt mat temperature immediately behind the paver(s) during placement.
The equipment uses infrared temperature measurement technology to measure a longitudinal thermal profile across the pavement width directly behind the paver. This system includes a display that allows the operator in the field to view a pavement surface temperature contour plot and automatically stores and saves the data for later review.
This standard practice is intended to be applied for construction quality control.
