1.4 Definitions
A.Binder lot – Specific to one approved binder, for one mix and for one particular project. A binder lot starts on a Saturday and ends on a Friday.
B.Compliance Limit – The limit for acceptance without price reductions, accounting for testing variability, for the listed properties.
C.Composite Price Reduction – The sum of price reductions for all individual properties associated with a single asphalt binder sample.
D.Rejection Limit – The limit for acceptance with price reductions. Material not meeting these limits will be rejected and removed and replaced.
1.5 Submittals
A.A vendor prepared bill of lading for information showing the following for each material shipment:
1.Type and grade of material
2.Type and amount of additives used, if applicable
3.Destination
4.Consignee’s name
5.Date of Shipment
6.Railroad car or truck identification
7.Project number
8.Loading temperature
9.Net weight in tons or net gallons corrected to 60 degrees F, when requested
10.Specific gravity
11.Bill of lading number
12.Manufacturer of asphalt material
1.6 Acceptance
A.The Department accepts, rejects, or applies price reductions to all mix lots for performance-graded asphalt binder (PGAB) lots according to the compliance and rejection limits of Table 1, the Minimum Sampling and Testing Requirements, UDOT Quality Management Plan 509, and the associated mix specification.
1.Rejected mix will be covered according to the associated mix specification including removal or if left in place the associated disincentive dollar amount for the rejected mix.
2.For material not meeting the compliance limit, but within the rejection limit, the price reduction applied to the mix pay item price is calculated as follows: Price Reduction (percent) = 25 × (Compliance Limit–Test Result) (Compliance Limit–Rejection Limit)
3.The composite price reduction will be calculated by summing the price reduction for each parameter if more than one parameter lies outside specification limits.
a.The mix material will be rejected if the composite price reduction exceeds 25 percent.
B.The maximum composite price reduction from the tested samples is applied to the mix in the binder lot if multiple samples from the binder lot are tested.
C.Adjacent samples in the preceding, current, or subsequent lots may be tested to assess the extent and limit the amount of mix to be rejected if a binder lot is rejected.
