ABSTRACT:
A road testing apparatus has a framework extending over a test portion of road pavement and has tracks with upwardly curved ends along which wheels of a trolley unit roll so that the trolley unit decelerates as it approaches an end position to cause kinetic energy to be transformed into potential energy and when return motion trolley commences the potential energy transforms back to kinetic energy. The trolley unit has a pivotally mounted base structure carrying a test load and a pair of road wheels which are mounted so as to be steered by the trolley as it progresses in a forward direction along the test pavement, additional wheels of the trolley running up an end portion of the track to lift the road wheels off the road surface as the end position is reached. A telescopic linkage latches into engagement at this end position to retain the road wheels in an elevated position relative to the trolley so that, during return motion, the road wheels can continue to rotate in the same direction but engage on the bottom of a base plate structure of the framework to drive the trolley in the reverse direction, the latch arrangement being released when the trolley reaches the opposite end position to permit a further cycle of operations.
