Specifications include, but are not limited to: 3/8” – No. 4 Aggregate, QTY 1000 Ton; Fractured Faces – Provide aggregates consisting of broken stone, crushed gravel or a combination of both. Crush aggregates such that at least 90% by weight of the total aggregate retained on the No. 8 and larger sieves is fractured on two faces, as determined according to AASHTO TP 61.; Grading – Perform sieve analysis according to AASHTO T 27 and AASHTO T 11. ; Unit Weight of Aggregate – Provide aggregate with a minimum unit weight of 90 pounds per cubic foot according to AASHTO T 19.; Soundness – Provide course and fine aggregate with a weighted loss not exceeding 12% when subjected to five cycles of the soundness test using sodium sulfate solution according to AASHTO T 104.; Aggregate Production Quality Control – Contract0r will provide quality control during production of aggregate according to ODOT Standard Specification for Highway Construction 2008 (OSSC) Section 00165. Sampling and testing shall be performed by a CAgT at the minimum frequency schedule indicated in the Manual for Field Test Procedures (MFTP). The cost associated with this testing shall be paid by Contractor. Contractor shall provide satisfactory test results to COBC prior to delivery of aggregate.: Quality Control Compliance – Evaluate aggregates for compliance to the following: h.1.a. Gradation – Analyze gradation statistically according to OSSC Section 00165. A stockpile contains specification aggregate when the Pay Factor (PF) for each sieve size calculated according to 00165.40 is equal to or greater than 1.00. Each required sample represents a sublot.; When the results from OSSC Table 00165-2 yield a Pay Factor of less than 1.00 for any sieve size, the material is non-specification. COBC will reject any stockpile of aggregate containing non-specification material unless the non-specification material is removed from the stockpile. Do not add additional material to such stockpile until enough nonspecification material is removed so that the PF for each sieve size is equal to or greater than 1.00.; h.1.b. Other Tests- Stop production, make appropriate operational adjustments, and remove all failing material from the stockpile whenever a quality control test result, other than sieve analysis, does not meet Specifications. Document operational adjustments made and notify COBC before resuming production.
