Abstract
Disclosed is a gasbag type pavement testing apparatus, comprising a main frame (), roller wheels () and a pneumatic suspension frame system which consists of gasbags (), ventilated bolts (), spokes (), an inflating valve (), a communicating shaft () and rockers (). The gasbags (), ventilated bolts (), spokes (), inflating valve (), and communicating shaft () constitute an air storing space interconnecting each gasbag, the air storing space is inflated or deflated through the inflating valve (), and the rockers () are hinge-jointed with the spokes (). The spokes (), rockers () and the communicating shaft () constitute a spoke assembly. The roller wheels () are driven by the spoke assembly to rotate round the communicating shaft (), the roller wheels () contact the pavement in turn under the joint action of the gasbags () and the spoke assembly to simulate the practical situation and hence conduct the rolling test for the pavement. The testing apparatus performs the test with higher accuracy and higher efficiency.
