 Goal of Optimized Aggregate Gradation and

Concrete Mixtures:

  • Increase the volume of aggregate while decreasing the

volume of paste.

 Paste = Binder + Water

Changes to Section 715 QMP Pavement and Structures

 715.3.1.2 Lot and Sublot Definition

  • Mix design change

 For paving mixes, a source change under item 1 of 710.4(5) for fly ash of the same class that does not require a modification under items 2 through 4 of 710.4(5) does not constitute a mix design change.  A new lot should be started when a new source is introduced however.

FLY ASH

 Class F Ash

  • Allowed on projects with a December 2016 or later LET.

 Not in the 2017 Standard Specifications  Allowed by ASP-6.

  • Must be listed of the departments APL, Approved

Products List.

  • Currently allows Prairie State Energy located in Marissa,

IL.

Changes to Section 106

 106.1.2 Project Materials Coordinator

  • (1) Ensure that this person is certified as having completed

the HTCP online materials coordinator training available at: https://www.uwplatt.edu/htcp/mct

  • (3) Also ensure that the contractor-designated materials

person participates in scheduled weekly construction meetings or meets with their department counterpart as requested.

 106.3.4.3.2 Process Control

  • (1) The department doesn’t require or use non-random

contractor tests for dispute resolution.
