Asphalt mixture data for AI load and sample matching

FHWA describes laboratory work on asphalt binders and mixtures.

FHWA describes laboratory work on asphalt binders and mixtures. A producer can propose a narrow task around connecting a load ticket to the sample and mix revision actually recorded. FHWA asphalt laboratory context

Write an original mock mix register, production log and dispatch ticket. Change the mix revision between two loads while retaining a similar short product code. Ask an assistant which sample report belongs to the selected load. Include a sample collected after the change and a proposed dispatch schedule that differs from the executed sequence. The reference answer should use execution evidence and retain any unresolved time boundary.

Label load, mix revision, sample time, test reference and source location separately. Evaluation can use a new ticket layout and a split delivery. Score wrong-revision matches, use of the planned sequence and unsupported sample associations independently. A matching mixture name alone should not establish that a report concerns this load.

Use invented records and values without preparing or handling material. Real customer mix designs, laboratory terms and plant exports need source-specific permission. Explain the load-association task and independent review in the licensing brief. The buyer's accepted specification should determine which production history and metadata justify further preparation.

Original Fiund exercise

A retained sample after a truck swap

An invented dispatch board tracks two inert sample jars; it contains no mix recipe.

Fictional records supplied to the evaluator
RecordSourceWhat it records
1Production logRun R8 produced loads L1 and L2, same mock mix ID.
2Dispatch amendmentTruck T3 swapped from L1 to L2 before departure.
3Sample ticketJar J17 drawn from L1 before the swap; truck field left blank.

Question for the model

What is J17 traceable to?

Show the reference answer and checks

J17 stays linked to L1 by record 3 and to R8 by record 1. The assignment of T3 to L2 in record 2 happened later and does not move J17's sampled material. Record truck history separately from sample lineage.

  • Joining on the current truck assignment
  • Extending a load sample to the entire run

Fields to preserve

load_id
Pins the represented material
sample_time
Places capture before or after a dispatch change
truck_effectivity
Distinguishes physical logistics from sampling

Test another case

Give two jars with the same truck and different loading intervals; match both the load and time.

No actual mix formulations, paving instructions, job sites or acceptance decisions.
