Abstract
An angle measuring device for use in a gyratory compactor. The device is a self-contained unit which is placed in the bottom of the mold and the asphalt or other material being compacted is placed on top of it. Inside the device is a carrier which has two vertically aligned probes which project out from it and touch the walls of the mold. One probe is fixed to the carrier; the other can move independently of the carrier. The difference in extension between the two probes is related to the angle of compaction.
