C. Report each day’s testing on a Quality Control Report, according to 446.04.
Report all testing performed by the Contractor’s technician on the Quality Control
Report. After startup adjustments, report any plant operation changes on the
Quality Control Report. Ensure that each Quality Control Report contains
technician comments as to production quality, input materials received, and
condition and includes any other quality control activities required in the QCP.
The Contractor’s technician must sign each Quality Control Report. Attach each
day’s computerized plant printouts to that day’s report. The technician must note
on the accompanying printout in which tonnage the quality control sample was
taken with accompanying test results for asphalt binder content and percent
passing the No. 4 (4.75 mm) sieve. Keep a copy of all Quality Control Reports for
a project in the Contractor’s plant laboratory.
The District will monitor according to 441.06, except notification for ceasing
production does not have to be in writing. Additional samples may be obtained for
Department test at any time.
For Basic mixes, if the mean of the Lot or partial Lot acceptance tests for any
sieve other than the No. 4 (4.75 mm) sieve exceeds the specification limits, the pay
factor is determined as follows:
TABLE 403.07-1 BASIC MIX PAY FACTORS
Number of Tests 1 2 3 4
Pay Factor 0.98 0.97 0.96 0.95
For Item 448 mixes, the Department will perform acceptance sampling and
testing according to 403.06 and 403.08, except the Lot size will be 5000 tons
(5000 metric tons) with 1250 ton (1250 metric tons). Sublots and acceptance
samples may be taken from the roadway or plant at the Districts discretion.
Department testing under Unconditional Acceptance will receive a lower testing
priority than other VA projects.
403.08 Acceptance Tables for 448 Mixes. A Lot is considered acceptable for
gradation and asphalt binder content if the deviation of the mean from the JMF and
the Range is no more than the tolerances shown in Table 403.08-1.
