Sequencing test methods so a novel binder either clears into production or fails early enough to allow a substitution before schedule is at risk.
The situation
A developer was preparing to introduce a calcined-clay binder system on a regional infrastructure pour with state-DOT proximity. The applicable test methods spanned ASTM, AASHTO, and F42 process specifications, and the overlap was not obvious to the developer’s project manager. A less-disciplined methodology would have triggered redundant testing and a calendar slip the project schedule could not absorb.
The work
A mapping of the applicable test methods across ASTM, AASHTO, and F42. A sequenced qualification plan with gating criteria at each stage, so a failure early in the sequence would trigger a substitution decision before the developer was committed to a binder that could not clear DOT review. The standardized schedule-and-cost comparison shown above, anchored to the industry-baseline trial-mix workflow, is the format we use to communicate the plan to a developer’s project manager.
The outcome
The qualification calendar shortened against the industry-baseline trial-mix workflow. The avoided-iteration line was material against the project’s lab budget. The developer’s project manager now uses the same sequencing template, and the comparison chart, for any new binder system entering the company’s project pipeline.
