Definition of Sampling Lot and Sublot
(January 16, 2014 APWA GSP)
Section 5-04.3(8)A4 is supplemented with the following:
For HMA in a structural application, sampling and testing for total project quantities
less than 400 tons is at the discretion of the engineer. For HMA used in a structural
application and with a total project quantity less than 800 tons but more than 400
tons, a minimum of one acceptance test shall be performed:
If test results are found to be within specification requirements, additional testing
will be at the engineers discretion.
If test results are found not to be within specification requirements, additional
testing as needed to determine a CPF shall be performed.
Going Forward
• Continue to gather Feedback about current APWA Div. 5 GSP’s
- Only minor desired revisions have been received.
• Make old WSDOT ATB specification available for use by GSP
• Research possibility of approval of Non-nuclear testing methods
AASHTO T343-12 - “Density of In-Place Hot Mix Asphalt (HMA) Pavement
by Electronic Surface Contact Devices.”
ASTM D7713-05 - “Standard Test Method for Density of Bituminous Paving Mixtures
in Place by the Electromagnetic Surface Contact Methods”
• Review Pervious HMA Pavements Specifications for possible inclusion as new
