Use in projects with Volumetric Acceptance of Hot Mix Asphalt. 03020.GR9 Test Methods for Aggregates 03020A.GR9 Statistical Aggregate Specification (August 6, 2007) When to use Statistical Aggregate Specification: This General Special Provision is an alternative to aggregate acceptance for unbound materials. The items which it may be used are Crushed Screening, Ballast, Shoulder Ballast, Crushed Surfacing, Maintenance Rock, Gravel base, Gravel Backfill for Foundation Class A, Gravel Backfill for Foundation Class B, Gravel Backfill for Walls, Gravel Backfill for Pipe Zone Bedding, Gravel Backfill for Drains, Gravel Backfill for Drywells, Backfill for Sand Drains, Sand Drainage Blanket, Gravel Borrow, Select Borrow, Foundation Materials Class A, Foundation Material Class B, Foundation Material Class C, and Bank Run Gravel For Trench Backfill. What this specification does is to recognize the variability of these materials and documents a procedure to adjust the payment for these items based on the Quality Level provided. In the past this would have required a Change Order. The process is particularly suited for production of aggregates stockpiled for use on future contracts or aggregates to be used on current contracts. A bid item "Aggregate Compliance Price Adjustment" needs to be included in the contract. 06.GR9 STRUCTURAL STEEL AND RELATED MATERIALS 06016.GR9 Roadside sign Structures 06161.GR9 (Perforated Steel Square Sign Posts) (August 2, 2004) Use in projects with perforated steel square sign posts. 14.GR9 EROSION CONTROL AND ROADSIDE PLANTING 1404.GR9 Mulch and Amendments 14048A.GR9 Compost (August 1, 2005) Must use once preceding the following: 140481.GR9, 140482.GR9 140481.GR9 (Compost) (August 7, 2006) Use when installing compost in areas receiving less than 10 inches of mean annual precipitation.
