3.11 SAMPLING AND TESTING FOR DENSITY

Delete in its entirety and replace with the following:

3.11 SAMPLING AND TESTING FOR DENSITY AND MIXTURE

Mixture sampling shall be performed before the material is compacted. Density testing shall be performed before allowing traffic or construction equipment on the placed mat and before the placement of the next lift. All sampling will be done by the Contractor. Quality Control testing will be performed by the Contractor. Acceptance testing will be performed by the City. All tests shall be performed by Certified Technicians and Testers in accordance with MSMT 731.

A. Mixture Sampling

An HMA mixture lot size is approximately equal to 6000 tons of a mix per project. A mix lot ends on the day when 6000 tons is reached. A mixture sublot size shall not exceed 1000 tons. A sublot size up to 200 tons can be combined with the previous 1000 ton sublot placed on the same day. A mix lot constitutes all sublots of a mix created during the production of required tonnage for a lot as defined herein. A new lot number for a mix will be given when there is a change in the approved job mix formula. Samples shall be obtained from the mat behind the paver in accordance with MSMT 457, Sampling HMA Prior to Compaction, as witnessed by the Engineer.

A minimum of two samples per mixture sublot, shall be obtained. The Contractor shall retain half of the mixture samples for Quality Control testing and the Engineer will take possession of the remaining mixture samples for acceptance testing.

1. Quality Control Testing

The Contractor shall test a minimum of one mix sample per sublot in conformance with MSMT 735 for asphalt content and gradation after each days paving operation and make the results available to the Engineer within five (5) working days.

2. Acceptance Testing

The Engineer will test mixture samples in conformance with MSMT 735 for asphalt content, gradation, and volumetrics. The Engineer may accept quality control test data without comparing them with acceptance data based on the Contractor’s past quality control and performance history.

Acceptance testing of these mixture samples will be in conformance with MSMT 735, Table 2. Mixture acceptance will be based on a composite percent within Specification limits (CMPWSL) of the lot based on asphalt content, voids total mix (VTM), percent passing No 4, No. 8, and No. 200 sieve material for dense mixes and gap-graded mixes.

B. Compaction Testing

An HMA compaction lot size shall equal one paving day’s production per mix. A lot shall be divided into a minimum of five equal sublots. A sublot shall not be greater than 500 tons.

When a paving day’s production per mix is greater than 2500 tons, then each sublot size shall be 500 tons or fraction thereof. Core locations shall be selected by the Engineer in conformance with MSMT 459 and taken by the Contractor in conformance with MSMT 458, as witnessed by the Engineer. The diameter of the cores shall be 6 in. except that a 4 in. core may be used for mixes smaller than 25 mm. Additional core locations for acceptance testing can be selected by the Engineer outside of the standard paving width.

A minimum of two cores per sublot shall be taken. The Contractor shall retain half of the cores for Quality Control testing and the Engineer will take possession of the remaining cores for acceptance testing.

1. Quality Control Testing

The Contractor shall test at a minimum one core per lift, per mix design, per daily occurrence, in accordance with MSMT 452. The Contractor shall make quality control test data available to the Engineer no later than the beginning of the next paving…
