Inquiry #69: According to the October 2022 Material Plant Quality Program Manual, section 2-6.02. Asphalt Rubber Binder Production states,
“ARB production consists of proportioning:
The preblended liquids. Combine with the proportioned scrap tire rubber and high natural rubber simultaneously and mix for the specified time at specified temperatures.
The method and equipment for combining liquid and dry ingredients must enable the resident engineer to readily determine compliance with proportioning requirements for each material and the completed ARB. The district weights and measures coordinator (WMC) must approve all required equipment before use.”
In order to meet the OCT 2022 MPQP Manual Update publication, simultaneously mixing both rubber types requires the rubber blending plant to have (2) rubber hoppers. One hopper would proportion the scrap tire rubber and the second hopper would proportion the High Natural Rubber. Without the presence of a second hopper, the data collection component of the required MPQP reporting does not align with the latest MPQP update.
Will the District Weights and Measures Coordinator be required to enforce the approved OCT 2022 MPQP Manual Update?
