Procedure and device for use with gravel and asphalt spreaders to optimize their working together

摘要

A fixed distance (D) is maintained between a gravel spreader (3) and an asphalt or bonding compound spreader (1). The gravel spreader is downstream from the asphalt distributor and its distribution gates are opened at a time interval after the spreader starts to ensure the gravel falls in the correct area. The device for carrying out the procedure includes an emitter/receiver in each vehicle for the bilateral transmission of data and orders to maintain the correct distance and operation.
