A GASBAG TYPE PAVEMENT ACCELERATED LOADING TESTING APPARATUS

摘要

Disclosed is a gasbag type pavement testing apparatus, comprising a mainframe (7), roller wheels (1) and a pneumatic suspension frame system whichconsists of gasbags (2), ventilated bolts (5), spokes (6), an inflating valve(10), acommunicating shaft (11) and rockers (3). The gasbags (2), ventilated bolts(5),spokes (6), inflating valve (10), and communicating shaft (11) constitute anairstoring space interconnecting each gasbag, the air storing space is inflatedordeflated through the inflating valve (10), and the rockers (3) are hinge-jointed withthe spokes (6). The spokes (6), rockers (3) and the communicating shaft (11)constitute a spoke assembly. The roller wheels (1) are driven by the spokeassembly to rotate round the communicating shaft (11), the roller wheels (1)contactthe pavement in turn under the joint action of the gasbags (2) and the spokeassembly to simulate the practical situation and hence conduct the rollingtest forthe pavement. The testing apparatus performs the test with higher accuracy andhigher efficiency.
