ABSTRACT:
A concrete paving system of a variety employing an array of vibrators which consolidate dispersed concrete over a roadbed or the like as the concrete is introduced to the mouth of a slipform pan or mold. The rate of vibration of these vibrators is monitored utilizing an accelerometer in conjunction with a vibration conversion network treating the acceleration signals to deriving vibration rate data which is published for each vibrator at a display. A controller with the system provides for the development of upper limit and lower threshold alarm limits which may be displayed along with audible warnings. Such vibration transducer based monitoring system also may be used for rotational component performance monitoring as well as in conjunction with probes located within distributed concrete in the vicinity of the array of consolidation vibrators to evaluate the performance of the latter. The monitoring system also is employable with the vibratory components of dowel bar insertion assemblies.
