SECTION 301 SOIL, SOIL AGGREGATE, AND AGGREGATE, BASE AND SUBBASES
301.01 Description.
a.General . This section shall cover the work of furnishing all materials and the construction of Soil, Soil Aggregate, and Aggregate, base and subbase courses, complete in place on the roadbed. Typical cross section, thickness, n umber, and material classification of the course will be shown in the plans or proposal.
b.Classification . The base or subbase materials are established by general classifications such as "Selected Material s", "Granular Soils", "Soil Aggregate", "Processed Reef Shell", and "Aggregates", and consist of natural soil, natural soil and natural aggregate combinations, or manufactured (commercial) aggregates, either used separately or blended in any combination wi th or without a stabilizing agent. Additional classification of the material by "Type" according to the required gradation and composition of the material in the completed base or subbase course have been tabulated in Sections 820, Selected Materials For B ases; 821, Granular Soil Materials; 822, Drainage Plane Materials; 823, Soil Aggregate Materials; 824, Processed Reef Shell Base Materials; and 825, Crushed Aggregate Base Materials. The bases and subbases will be further established by the method of mixin g, (Road, Yard, or Plant) as described in Article 301.03. The general classification, type, and method of mixing will be shown in the proposal. Special details will be shown on the plans.
301.02 Materials.
All materials furnished for use shall comply with the requirements of the applicable sections of
Division 800 — , Materials, except as modified by the plans or proposal.
Attention is directed to: • Section 807 Water • Section 815 Cement • Section 817 Lime for Roadbed & Base Stabilization • Section 820 Selected Materials for Bases • Section 821 Granular Soil Materials • Section 822 Drainage Plane Materials • Section 823 Soil Aggregate Materials • Section 824 Processed Reef Shell Base Materials • Section 825 Crushed Aggregate Base Materials Preliminary tests o f optional sources shown on the plans indicate that the materials from these sources will meet plan requirements, either in their natural composition or by blending with additional material. However, whether sources are shown on the plans or not, the Contr actor shall supply whatever components are needed, in whatever proportions are necessary, to meet specified requirements of the plans and specifications for the item complete in place. The processed materials, in addition to complying with the requirements noted above, must be capable of being compacted to the density requirements noted in this Section. Any material furnished, regardless of compliance with all other requirements, which cannot be compacted to the densities specified shall be either removed a nd replaced with more suitable material, or corrected. Testing of material will be as provided in Article 301.05.
