501.01 Description.
501.01.1 General: Furnish and construct one or more courses of
asphalt concrete mixture in conformance with these specifications and in conformity with the lines, grades, thicknesses, and typical sections shown on the plans or established. Comply with Section 503 , Equipment and Processes and the Application of Quality Assurance Specifications for Asphalt Concrete Mixtures (QA Manual). These specifications apply to all asphalt concrete mixtures with plan thicknesses less than 1½ inches. The following mixtures are further described herein and as shown on the plans:
1.Dense Mix – allowed for traffic volumes < 3,500 ADT.
2.Coarse Mix – allowed for all traffic volumes. Can be subst ituted for Dense Mix without change order.
3.Open Graded Friction Course (OGFC) – allowed for all levels of traffic volume, and required when used on Interstate Highway System. The OGFC can be substituted for any Thin Asphalt Concrete application without change order. Use the same mixture type throughout the project length unless approved otherwise by the engineer.
501.01.2 Quality Assurance: It is the intent of these specifications
that the mixtures produced and placed meet the requirements for 100 percent payme nt. Work shall meet the requirements of this section and be subject to acceptance by the Department. Exercise quality control as defined in 101.03 . When these sp ecifications are not being met and satisfactory control adjustments are not being made, discontinue operations and notify the project engineer immediately until proper adjustments and uniform operations are established. Accomplish control by a program ind ependent of the Department's testing and ensure that the requirements of the job mix formula (JMF) are being achieved and that necessary adjustments provide the specified results. Do not begin daily plant operations unless the contractors’ Certified Asphal t Concrete Plant Technician (Level 2 or Level 3) is at the plant. When the plant is in operation, have a Certified Asphalt Concrete Plant Technician at the plant or jobsite.
