Abstract (en)
[origin: CN204174508U] Provided is a device used for measuring a contact range (alpha) for expressing contact status between a compactor roller and a foundation to be compacted. The device comprises one or more contact sensors (1, 2, 3 and 4), wherein the contact sensors are located in one or more collection circumference areas (18, 20, 22 and 24) of the compactor roller (12) capable of rotating around a compactor roller rotation axis (D), and are used for generating contact signals; the contact signals are used for indicating contact initial positions (A) and contact end positions (E) of the collection circumference areas (18, 20, 22 and 24) and the foundation (14) to be compacted.
