IA Reviews

• Independent Assurance (IA) is unbiased testing and review of DOT, consultant, and contractor personnel who sample and test on our DOT projects.

• IA goals is review 90% of the samplers and testers on our projects.

IA Reviews

• If a QV technician samples or tests on your project we would conduct an IA review.

• We will check with PE and MTS through out the project to meet compliance.

IA Reviews

• Problem areas (past)• QV testing on small

bridge projects.• Last minute QV base

course samples.

IA Reviews

• QC testers (contractors)• Coordination between

offices.• Help from project staff.

Alkali-Silica Reactivity

• Marathon County• Quarries containing –

rhyolite, diorite, gniess, and quartzite.

• Hanz, 3M, and Weisenberger Quarries.

Alkali-Silica Reactivity

• A process in which silica in the presence of moisture, is broken down by alkalis produces an expansive gel.

• The expanding gel creates internal forces that causes the concrete to crack.

Alkali-Silica Reactivity

• Concrete coarse aggregate needs to meet ASTM C1260 (every 3 years).

• Special Provision for 2014 –

• Spec Book in 2015.

Alkali-Silica Reactivity

• If fails…• 1. Use 35% slag grade

120.• 2. Class “F” fly ash• 3. Mix specific test

ASTM C1567 (every 3 years).

• Cement / fly ash • Blend (percentages) and

sources.

Alkali-Silica Reactivity

• Weisenberger Quarry has two approved C1567 mixes (County Materials – Marathon City and Rothschild plants).

QMP Base Compaction

• Criteria: Projects with• 30,000 tons or more of

1.25” BAD with sub grade improvement.
