Excavation shall consist of excavating and grading for parking areas;

excavating the top 40 centimeters of surface soil and additional unsuitable material, regardless of character, from the subgrade; and disposing of all excavated materials, as specified and in conformity with the lines, grades, cross sections, and dimensions shown on the drawings, and to replace unsatisfactory materials from other excavation or grading operations.

Paragraph: 3.3.5 Subgrade Preparation for Roadways and Parking

After the grading is substantially complete, and immediately in advance of depositing the surfacing material, the subgrade shall be brought to the proper lines, grades, and cross sections as indicated and in accordance with these specifications. All depressions and ruts shall be removed by blading and dragging so as to secure a uniform surface. The entire subgrade shall be brought to a firm, unyielding surface, true to line, grade and cross section, by rolling with an approved power roller, weighing not less than 9500 kilograms, until thoroughly compacted. This operation shall include any reshaping and wetting required to obtain proper compaction. All soft, spongy, or yielding spots shall be entirely removed and the space refilled with suitable material and thoroughly compacted. The top of the subgrade shall be of such smoothness that when tested with a 5 meters straightedge it shall not show any deviation greater than 12 millimeters.

Subgrade compaction shall be extended onto the shoulders for a distance of at least 30 centimeters beyond the edges of the base course or pavement. The subgrade shall be maintained in the finished condition until the first course of surfacing has been placed.
