	A sample of air-entraining admixture, water-reducing admixture, or retarding admixture shall consist of one quart (1 liter) of material in a ~~screw top can~~. A sample of accelerating admixture or latex emulsion admixture shall consist of one gallon (4 liters) of material in a plastic container. All samples shall be obtained by the manufacturer or contractor’s agent in accordance with the manufacturer’s sampling instructions. The inspector will observe the sampling process. The sample shall be recorded through SiteManager showing the manufacturer's name, the brand name and designation of the material, lot number, net quantity represented, and the location where the sample was obtained using the Sampled From and Sample Origin fields of SiteManager. The Other tab is also used for a Mixing Facility. The PAL ID number obtained by the supplier or mixing facility in accordance with EPG 1054.2.5 Sample Record should be recorded in SiteManager in the “Link To” field.

	Material is accepted by the PAL criteria as indicated in [[106.2 Pre-Acceptance Lists (PAL)\|EPG 106.2 Pre-Acceptance Lists (PAL)]]. The State Construction and Materials Engineer will retain the original certification and guarantee. Additional certification is not necessary if the manufacturer and brand of material is clearly identified on the container or the documentation included with bulk shipments.

	Each admixture producer will be assigned to a district office for Facility Review, Sampling and Testing in accordance with [[106.2 Pre-Acceptance Lists (PAL)\|EPG 106.2 Pre-Acceptance Lists (PAL)]]. During the visit, samples of material available at the facility should be obtained. Materials selected for sampling will tpically be those that have been used in MoDOT work during the past month. Material originating at locations too far from the assigned district’s office is subject to sampling at an intermediate location or at the job site. It is the assigned district’s responsibility to verify with the supplier that the location seleted for sampling is acceptable to the supplier as a location from which a valid PAL source sample may be obtained.

	For material shipped directly to a job site by a supplier, the supplier shall notify the State Construction and Materials Engineer prior to shipment using [http://www.modot.mo.gov/business/materials/pdf/vol_1/GS013F3.pdf GS-13 Form 3]. When the material is shipped to a mixing facility, that facility shall notify the State Construction and Materials Engineer of its arrival using [http://www.modot.mo.gov/business/materials/pdf/vol_1/GS013F2.pdf GS-13 Form 2]. When complete and correct information on the shipment is provided to the State Construction and Materials Engineer, a PAL ID number will be assigned to the material. That number shall be attached to the material container, or be immediately available at the plant, until the material is consumed. The proportioning plant inspector shall continue to show on the daily reports the information required by the [[:Category:500 RIGID PAVEMENT\|Construction Inspection Guidelines in the Engineering PolicyGuide’s Rigid Pavement articles]].

	Material purchased for maintenance work may be accepted solely on the basis of the manufacturer and brand being on the Pre-Acceptance List. District Materials will report the receipt and acceptance of the material in SiteManager and will mark the containers with the sample ID number they assign.
