This document is a Materials Procedure (MP 401.02.22) from the West Virginia Department of Transportation, Division of Highways, Materials Control, Soils and Testing Division, dated January 4, 2023. It outlines the "Guide to Designing Hot-Mix Asphalt Using the Marshall Design Method."

This document details the procedures, test methods, and criteria for establishing approved Marshall design methods for hot-mix asphalt (HMA). It specifies required testing, referenced standards (AASHTO and ASTM), and design criteria for various traffic levels (Medium, Heavy, Base-I, Wearing-I, Wearing-III). It also outlines the reporting requirements for submitting a Job Mix Formula (JMF) package. This information is crucial for any bidder involved in asphalt mixture design and quality control for projects requiring adherence to West Virginia DOT standards.

Solicitation / RFP / RFQ

This document outlines the specifications for "SECTION 401 ASPHALT BASE, WEARING, AND PATCHING AND LEVELING COURSES." It details the requirements for constructing one or more courses of asphalt concrete, mixed mechanically in a plant, designed in accordance with the Marshall design system. The work involves preparing a foundation and applying asphalt concrete in reasonable conformity with specified lines, grades, weights, thicknesses, and cross-sections shown on plans or established by the Contracting Officer's Representative (COR).

• Materials: Specifications for Coarse Aggregate, Fine Aggregate, Mineral Filler, and Performance Graded Binders (standard grade PG 64S-22). Recycled Asphalt Pavement (RAP) is not permitted.

• Job Mix Formula (JMF): Contractors must submit a proposed JMF for each asphalt concrete combination, detailing material sources, aggregate blend percentages, optimum asphalt content, mix temperature, and Fines to Asphalt (FA) ratio. JMFs require COR review and approval.

• Aggregate Gradation: Specific aggregate gradation requirements are provided for different mix types (BASE-I, BASE-II, WEARING-I, WEARING-III) in Table 401.4.2A.

• Testing: Comprehensive testing methods are outlined, including sampling, aggregate analysis, asphalt content determination, and resistance to plastic flow. Quality control testing is the contractor's responsibility, requiring certified personnel and equipment.

• Compaction: Detailed procedures for compaction, including roller passes and density testing (using nuclear methods and Rollerpass testing), are specified. Minimum density requirements are 92% of Gmm, with adjustments to contract price for deviations.

• Surface Tolerance: Finished courses must present a uniform surface with specified maximum deviations from a straightedge.

• Weather Restrictions: Paving is restricted by surface and air temperatures, with specific guidelines for cold weather paving.

• Equipment: Requirements for plants, dust collectors, truck scales, paving equipment (pavers with grade and slope controls), and compaction equipment are detailed.

• Paving Operations: Includes cleaning, sweeping, patching, leveling, scratch courses, spreading, finishing, and joint construction.

• The unit of measurement for asphalt concrete is by the ton, square yard, or cubic yard.

• Payment is based on contract unit prices for specific pay items, including "design method" Asphalt Base Course, Wearing Course, Patching and Leveling Course, and Scratch Course.

• Adjustments to contract price will be made based on pavement density achieved.
