If the results of the aggregate grading tests do not meet the requirements for Percentage Passing Sieve as specified in Table 200-2.2.2, but meet the Quality Requirements as specified in Table 200 -2.2.3, placement of the aggregate base may be continued for the remainder of that day. However, another day's Work may not be started until test results indicate to the satisfaction of the Engineer that the next material to be used in the Work will comply with the requirements specified for Percentage Passing Sieve.
3. If the results of both the aggregate grading and Sand Equivalent tests do not meet the requirements of Section 200-2.2, the aggregate base which is represented by these tests shall be removed. However, if requested by the Contractor, and approved at the sole discretion of the Engineer, the aggregate base may remain in place and the Contractor shall pay to the Agency $50 per cubic yard for such aggregate base left in place. The Agency may deduct this amount from any moneys due, or that may be come due, to the Contractor under the Contract.
ADD 200-2.9 Class 2 Aggregate Base.
Aggregate for Class 2 aggregate base shall be free from organic matter and other deleterious substances, and shall be of such nature that it can be compacted readily under watering and rolling to form a firm, stable base. Aggregate may include material p rocessed from reclaimed asphalt concrete, portland cement concrete, lean concrete base, cement treated base or a combination of any of these materials.
Aggregate shall conform to the grading and quality requirements shown in the following tables.
At the option of the Contractor, the grading for either the 11/2 -inch maximum or 3/4 inch maximum shall be used, except that once a grading is selected it shall not be changed without the Engineer's written approval.
