303.01 DESCRIPTION. This work consists of providing special graded aggregate as surface
courses for driveways or shoulders to be placed in reasonably close conformity with the lines, grades, and typical cross sections indicated on the Plans, all in accordance with these Specifications. 303.02 MATERIALS. Special graded aggregate shall be a composite mix of crusher run coarse aggregate and fine aggregate, free from clay, loam, so ft or elongated rock fragment s, organic soil or vegetative matter. Coarse aggregate (plus No. 4) shall consist of clean, hard, durable particles of crushed rock fragments or crushed gravel. Crushed gravel shall cons ist of 95 percent by weight particles with at least one fractured face. Coarse aggregates shall have a percentage of wear by the Los Angeles Abrasion Test (AASHTO T96) of not more than 50 percent, and a Sodium Sulfate Soundness (AASHT0 T104) of not more than 12 percent. Fine aggregate shall consist of particles produced during the crushing of coarse aggregate at the approved source and shall be free of organic deleterious matter. The composite coarse and fine aggregate mix shall conform to the following gradation requirements, as well as all other applicable specifications prior to its final placement on the Project: Square Mesh Percentage by Weight Passing Sieve Size: Indicated Square Mesh Sieve: 1½" 100 1" 85 - 100 ½" 50 - 85 No. 4 40 - 75 No. 40 8 - 35 No. 200 2 - 10 Coarse and fine aggregates to be used as Special Graded Aggregate for driveway or shoulder surfaces shall be selected to provide a stable, compactable, functional and presentable surface which shall be similar in color and texture, as approved by the Engineer, to match existing surfaces. 303.03 CONSTRUCTION METHODS. 303.03.1 Placing. When used as a crushed aggregate surface course to provide a transition between existing gravel/aggregate surfaces and new asphalt, special graded aggregate shall be placed in layers such that the maximum compacted thickness of any one layer shall not exceed 6 inches. 303.03.2 Shaping and Compaction. Special graded aggregate shall be shaped and compacted 3−4 in accordance with the requirement of Subsection 301.03.2; Shaping and Compaction , of these Specifications. 303.04 METHOD OF MEASUREMENT. "Special Graded Aggregate" will be measured by the number of cubic yards or the number of tons, as the case may be, actually placed in accordance with the Plans and/or as directed by the Engineer.
303.05 BASIS OF PAYMENT. The accepted quantity of "Special Graded Aggregate" will be paid
for at the contract unit price per ton or per cubic yard, as the case may be, as listed in the Proposal. The price so-stated shall constitute full and complete compensation for all labor, materials, and equipment, including trimming and fine grading, and all incidentals required to finish the work, complete and accepted by the Engineer. SECTION 304 SELECT LEVELING AND FILLER AGGREGATE
304.01 DESCRIPTION. This work consists of providing select leveling and filler aggregate to
adjust subbase or subgrade surfaces to close conf ormance with the lines, grades, and typical cross sections indicated on the Plans, all in accordance with these Specifications. 304.02 MATERIALS. Select leveling and filler aggregate shall be a composite of crushed or uncrushed coarse aggregate and natural or crushed fine aggregate, all provided from approved sources. The composite aggregate shall be free of compressible or organic soils, soft or elongated rock fragments or gravel, and vegetative matter. Coarse aggregate (plus No. 4) may consist of crushed rock fragments, crushed or uncrushed gravel, or a blend of crushed and uncrushed rock and gravel. Each coarse aggregate component source material shall have been shown i ndividually to have a percentage of wear by Los Angeles Abrasion Test (AASHTO T96) of not more than 50 percent, and a Sodium Sulfate Soundness (AASHTO T104) of not more than 12 percent. Fine aggregate may consist of natural sand or particles produced by crushing rock or gravel, and shall be free of organic soils or other deleterious matter. The composite coarse and fine aggregate mix shall conform to the following gradation requirements, as well as all other applicable specifications prior to its final placement on the Project:
