301.01 DESCRIPTION. Furnish and place class I roadway and shoulder
base courses on a subgrade layer conforming to Section 305 in accordance with these specifications and in conformance with the lines, grades, thicknesses, and typical cross sections shown on the plans or established. Control the selection, placement , mixing, and compaction of materials so that the completed base course is uniform and conforms to plan dimensions and other acceptance requirements. Quality assurance requirements shall be as specified in the latest edition of the Department’s publication titled Application of Quality Assurance Specifications for Embankments and Base Course. When not specified, any of the following types may be used:
1.Soil Cement
2.Crushed Stone
3.Asphalt Concrete Base Course on Treated Layer
4.Recycled Portland Cement Concrete
5.Blended Calcium Sulfate Select a base course type meeting the structural requirements for a specific pavement structure. Unless approved otherwise in writing, use the same type of Class I base course throughout the project in accordance with these specifications. In areas inaccessible for mixing and compacting in turnouts, crossovers, or other isolated or irregular areas, portland cement concrete complying with Section 901 , or asphalt concrete base course complying with Section 502 , may be used in lieu of the specified base course material with approval. If using asphalt or portlan d cement concrete, the top half of the base thickness shall be asphalt or portland cement concrete. If used, portland cement concrete shall be a minimum thickness of 6 inches. The remaining thickness shall be the same type and constructi on as the top layer of embankment, treated layer, or subgrade. Do not place raw, untreated material between a treated embankment and the concrete. Place, consolidate, finish, and cure concrete as directed in accordance with Section 706 . Submit a dust control plan to address weather, sight clearance, operational procedures, traffic control, and any other project specific concerns. Failure to maintain sight cle arance will result in the engineer stopping contractor operations. acceptable epoxy or plastic material for a minimum distance of 2 inches from the point of cont act with the forms.
