Written by GovTribe AI ·

This document is a Group Specification (Spec-949) for Bituminous Concrete Asphalt Mixtures, issued by the New York State Office of General Services, Procurement Services, located in the Corning Tower at the Empire State Plaza in Albany, NY. The specification is dated October 15, 2024, and supersedes the previous Spec-948 dated January 8, 2024. It is primarily intended for the New York State Department of Transportation (NYSDOT) and other potential agencies seeking asphalt pavement and asphalt pavement with fibers materials.

The specification covers a comprehensive range of asphalt mix types, including various nominal maximum sizes (37.5, 25.0, 19.0, and truing and leveling courses) with different compaction series and fiber options. The document provides detailed material requirements, including a unique provision for incorporating crushed glass up to 5% of the total aggregate weight, subject to Regional Materials Engineer approval. A Quality Adjustment Factor (QAF) is outlined, with index prices varying by region from $80 to $140 per quality unit, specifically for NYSDOT. The specification references the NYSDOT Standard Specifications with an effective date of January 1, 2025, and includes links to comprehensive pavement design manuals and material methods for precise implementation.

If the Contractor chooses the crushed glass option, the following modifications to the Standard Specifications shall apply:

MATERIAL REQUIREMENTS:

Crushed glass shall be subject to the approval of the Regional Materials Engineer prior to its use. The crushed glass shall contain no more than 1% (by weight) contaminants and shall meet the following gradation:

Sieve Size Percent Passing 3/8 in. 100 1/4 in. 90-100 No. 20 0-20

Note: The gradation requirements may be modified upon approval of the Regional Materials Engineer.

Crushed glass may be included in the mixture up to 5%, maximum, of the total aggregate weight. The crushed glass, aggregate and added asphalt cement shall meet the requirements specified in Table 401-1, Composition of Asphalt Mixtures and latest MM 5.16, for aggregate gradation, PG binder content, PG binder grade and temperature range.

CONSTRUCTION DETAILS:

The crushed glass shall be proportioned from a separate feed bin approved by the Regional Materials Engineer.

In addition, all requirements pertaining to aggregate shall apply to crushed glass including the equipment requirements for automatic proportioning and recording stipulated for aggregate in §401-3.08.
