Recordation of Quantities of Materials Incorporated in Base and Pavement Plant Mixtures.

摘要

This is the second phase of research to develop an independent monitoring and recording system. The system is to provide a record of the weights of each ingredient for each batch produced in weight proportioning batch plants,completely independently from the plant operating system. In this phase a prototype system including four load cells supporting each weigh hopper,acting independently from the plant level system,was installed on a commercially operated,fully automated asphalt concrete batch plant. The load cell output was translated through processing instrumentation into both a printed tabulation and punched tape record for each batch. The system was operated for a thirteen month period during which numerous observations and comparative weighing tests were made. (Modified author abstract)
