Abstract: The present disclosure provides a total-environment full-scale cyclic accelerated loading experimental system, which pertains to a field of accelerated loading experimental systems. The total-environment full-scale cyclic accelerated loading experimental system includes a rack, and a power mechanism, a chain drive pair, a roller set, a guide rail, etc. installed on the rack. The power mechanism is connected to the roller set through the chain drive pair. The roller set is matched with an annular loading surface of the guide rail. In the present disclosure, in addition to an environmental unit being provided on the rack, modifications are made to structures of the guide rail, the roller set and the chain drive pair as well as connections thereof.

Abstract: A constant temperature circular accelerated loading test system includes: a chassis; a motor reducer and a circular loading wheel group in the middle of the chassis, wherein the motor reducer provides power for the circular loading wheel group, and the circular loading wheel group implements a rolling test on a ground during rotation; a thermally insulated assembly on the chassis, the circular loading wheel group is located in a thermally insulated inner cavity of the thermally insulated assembly; a constant temperature unit on the chassis; a control cabinet on the chassis, wherein the control cabinet is connected to and controls the constant temperature unit and the motor reducer, respectively.

Abstract: Disclosed is a gasbag type pavement testing apparatus, comprising a main frame (7), roller wheels (1) and a pneumatic suspension frame system which consists of gasbags (2), ventilated bolts (5), spokes (6), an inflating valve (10), a communicating shaft (11) and rockers (3). The gasbags (2), ventilated bolts (5), spokes (6), inflating valve (10), and communicating shaft (11) constitute an air storing space interconnecting each gasbag, the air storing space is inflated or deflated through the inflating valve (10), and the rockers (3) are hinge-jointed with the spokes (6). The spokes (6), rockers (3) and the communicating shaft (11) constitute a spoke assembly. The roller wheels (1) are driven by the spoke assembly to rotate round the communicating shaft (11), the roller wheels (1) contact the pavement in turn under the joint action of the gasbags (2) and the spoke assembly to simulate the practical situation and hence conduct the rolling test for the pavement.

Abstract: Disclosed is a floating mechanism loading vehicle provided with double shafts and eight wheels for pavement accelerated loading test. The floating mechanism loading vehicle comprises front and rear rotating shafts (5), on each of which two loading steel wheels (3) and two backhaul steel wheels (2) are mounted, the loading steel wheels (3) being fixed on the rotating shafts (5) and the backhaul steel wheels (2) being rotatable round the rotating shafts (5). During the loading rolling course, the loading steel wheels (3) runs on the loading rail (4), while during the unloading backhaul course, the backhaul steel wheels (2) runs on the backhaul rail (1).
