Sampling

When the quantity of material proposed for TxDOT use meets the minimum quantity of material eligible for inspection, as stated in the Warehousing Agreement, the warehouse is responsible for contacting the TxDOT Designated Sampler to arrange for sampling. Out-of-state warehouses contact the Responsible Branch, that will then arrange for sampling.

When the quantity of material proposed for TxDOT use does not meet the minimum quantity of material eligible for inspection, the warehouse must first contact and receive approval from the Responsible Branch of the material. If approval is granted, the Responsible Branch contacts the Designated Sampler and advises him or her of the change. The Designated Sampler contacts the warehouse to arrange for sampling.

Upon arrival, the Designated Sampler obtains the completed Form 1908 from the warehouse representative. The Designated Sampler is responsible for verifying the material identification (Batch/Lot/Heat/Coil numbers) and quantities listed on the form against the material presented for sampling. Any discrepancies in identification and quantities found by the Designated Sampler is brought to the immediate attention of the warehouse representative for corrective action. In the event a violation of the agreement or of this procedure is discovered, the violation will be handled as outlined in the Clandestine Activity section of this chapter.

Sampling is conducted according to the applicable TxDOT test method.
