documentation within seven calendar days of sampling, in accordance with Subsection 407.4.2, Sampling Procedures, the engineer will reduce the payment by as much as 25 percent for that load.
The engineer may reduce the payment for emulsified asphalt that does not meet specifications but is accepted in accordance with Subsection 113.2, Acceptance of Asphalt Materials. 404.5.4.2 Plant Mix Wearing Course 1 The engineer will calculate pay adjustments for aggregate gradation and asphalt binder
content using the following formulas: =
0.67 x PMWC x (PFA – 1) x LSA

Plant Mix Pavement (Commercial Mix)
406.1DESCRIPTION
1 This section describes the requirements for providing, hauling, and placing one or more
courses of commercial plant mix on a prepared foundation.
406.2MATERIALS
2 Provide plant mix pavement composed of a mixture of aggregate and asphalt binder
from a commercial source. Obtain the engineer’s approval before adding natural fillers or commercial additives.
406.3EQUIPMENT
1 Provide equipment in accordance with Subsection 401.3, Equipment.
406.4CONSTRUCTION
1 Observe weather and temperature restrictions in accordance with Subsection 401.4.2,
Weather and Seasonal Limitations. 2 At least 14 calendar days before use, submit the name of the proposed commercial
source and a proposed mix design for the plant mix pavement to the engineer for approval. The mix design may be referenced to a mix design approved within 2 years of the award date of the contract. 3 Spread and finish the mix in accordance with Subsection 401.4.19, Spreading and
Finishing. 4 Compact the mix to ensure an in-place density that equals or exceeds 92.0 percent of
maximum density. 5 Ensure surface variations are as specified in the contract.
406.5MEASUREMENT and PAYMENT
406.5.1 General 1 The engineer will measure Plant Mix (Commercial) by the short ton [metric ton].
