Precision Approach Radar (PAR) or Airport Surveillance Radar (ASR) approaches are considered a terminal procedure and are found along with all the other terminal procedures.
The page for PAR or ASR information will be listed under RADAR MINIMUMS with other terminal approach procedures.
For example, if you look at KTUL on the Airports page and select PROCEDURES and then APPROACH, you will see a terminal procedure listed as RADAR MINIMUMS. Tap on that for the information about applicable PAR or ASR approach minimums.
