1 If the samples for a truckload are not received by the Materials Program with proper
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 payment for emulsified asphalt that does not meet specifications but is accepted in accordance with Subsection 113.2, Acceptance of Asphalt Materials.

Prime Coat
408.1DESCRIPTION
1 This section describes the requirements for preparing and coating an existing surface
with prime coat and, if required, blotter.
408.2MATERIALS
1 Provide materials in accordance with the following:
Material
Subsection
Aggregate for Blotter Emulsified Asphalt
803 804.3
2 Provide either emulsified cutback asphalt, AEP, or penetrating emulsion prime (PEP). 3 Provide blotter material from a specified department-furnished or contractor-furnished
source.
408.3EQUIPMENT
1 Provide tank trucks, asphalt distributor, and on-site storage tanks in accordance with
Subsection 407.3, Equipment. 2 Provide mechanical spreading equipment for applying blotter material; do not use hand
tools unless approved by the engineer.
408.4CONSTRUCTION
408.4.1 General 1 Ensure the application surface is shaped to the required grade and section, free of ruts,
corrugations, segregated material, and other irregularities and uniformly compacted. Reprocess or reshape damaged areas. Obtain the engineer’s approval of the surface before applying prime coat. 2 Provide samples and certification documents for emulsified asphalt in accordance with
Materials Testing Manual, Section 840.0, Liquid Asphalt Sampling. 3 When using PEP, pre-wet surface with water in accordance with Subsection 209.4.2,
Prewetting, to reduce surface tension of fine particles and maximize penetration of prime coat. Apply prime coat when the application surface is damp and both the air and surface temperatures are above 50 °F [10 °C].
