403.1.5 under Gradation line 4 and 5 shouldn't the sentance"QA is required to independently sample the aggregate and perform a sieve analysis once per lot." read "once per day."?
Dan Tschirgi: Thank-you for your inquiry. Current Standard Specification 403.19.3 requires 1 sample per lot for QA. Sec 403.18.1 also has a requirement for QA testing of one retained sample per week. Please contact the Construction and Materials Division if you have additional questions on this requirement.
