Due to the duration of most maintenance projects, no partial payment progress estimates will be made. In those cases, only one final progress payment will be made. However, if a project is scheduled to last longer than 3 months, a progress estimate will be made quarterly or every 3 months.

The following requirements must be met:

1.12.1.1. The aggregate meets the contract requirements.

1.12.1.2. The aggregate is stored to prevent damage and theft, without obstructing or impeding the traveling public.

1.12.1.3. A written request for payment must be submitted to the Maintenance Chief. The request must include the crushed aggregate quantity and cost for which payment is requested and the length of time the material is to be stored.

1.12.1.4. If the Contractor has subcontracted the crushing, then a notarized statement from the subcontractor certifying that their payment has been received must be included with the partial payment request.

1.12.1.5. Partial payment is not an approval of the furnished aggregate. Approval of the furnished aggregate will be made at the time the aggregate is actually used.

1.12.1.6. Partial payment will only be considered for Commercial Plant Mix and/or Grade 4A Chips.

1.12.1.7. Partial payment will not exceed 35% of the total line item cost.

1.15. SPECIAL PROVISIONS – COMMERCIAL PLANT MIX BITUMINOUS SURFACING

(Revised 2-01-13)

1.15.1. Description

This work is producing, furnishing, placing and compacting Grade S Plant Mix Bituminous Surfacing on an approved surface.

1.15.2. Material

Refer to the “Standard Specifications for Road and Bridge Construction”, 2020 edition as amended by current supplemental specifications (effective on the bid opening date).

1.15.3. Construction Requirements

1.15.3.1. Hamburg Wheel Tracking

1.15.3.1.1. The Department may require Hamburg samples at any time. Provide the Project Manager samples of plant mix surfacing material for Hamburg Wheel Track acceptance as directed.

1.15.3.1.2. Remove and replace any plant mix represented by a failing Hamburg test at no cost to the Department.

1.15.3.1.3. When a Hamburg sample does not meet the requirements, suspend production, and submit a revised mix design and samples for verification and Hamburg Wheel Track testing. Do not resume production until the revised mix design is verified and Hamburg Wheel Track mix design requirements are met.

1.15.3.2. Density Acceptance by Cores

1.15.3.2.1. Perform all necessary density testing to control compaction. Complete compaction rolling within the temperature range recommended by the asphalt binder supplier included in the mix design. Suspend paving operations when compaction rolling damages the new pavement.

1.15.3.2.2. Once the plant mix is spread, struck off, and surface irregularities are corrected, compact the plant mix to at least 92.0 percent of the target Maximum Specific Gravity as determined using MT-328.

1.15.3.2.3. Provide core samples of the compacted plant mix from the roadway. Core locations will be selected randomly based on the tons of mix placed. Provide cores to the Project Manager after all rolling is complete and before the roadway is open to traffic. Areas within 12 inches of longitudinal paving joints, 12 inches of a shoulder hinge point, or where the planned nominal thickness is less than 0.10 foot, will not have sample locations designated within them. The pavement density is determined from cores taken at randomly selected locations after all rolling is complete and before the roadway is open to traffic. Density acceptance by cores does not apply to leveling or isolation lifts that have a depth of less than 0.10 foot thick.

1.15.3.2.4. Provide two 4-inch cores the full depth of the plant mix surfacing, extracted from within a 5-inch radius of each designated location. Mark the core as directed. Separate the plant mix lift to be tested from the total core. Cut the core to the actual lift thickness within plus or minus 0.15 inch. The Department recommends using a saw to separate the lift to be tested from the total core. Perform this work within the project limits or other approved location.

1.15.3.2.5. Furnish the core immediately to the inspector after it is removed, marked, and separated. Do not remove the cores from the Inspector’s visual control at any time. Re-core as directed any time either the Contractor requirements or procedures within this section are not met. The test results of the replacement core to be used in the QA evaluation for the lot represented will be the actual relative in-place density unless it exceeds 91 percent. If the actual in-place density of the replacement core is greater than 91 percent, then 91 percent will be used for the relative in-place density of that core in the QA evaluation. The plant mix in the sub lot represented is considered to not meet minimum density specifications.

1.15.3.2.6. Remove free water from each core hole, place, and compact new plant mix (or approved cold patch mix) not exceeding 2-inch lifts to the finished surface immediately after the core is removed.

1.15.3.2.7. MT 328 is used to establish the target Rice density. The Bulk Specific Gravity (MT 314) determined for each core will be divided by the target Rice density in effect at the time the plant mix was produced to determine the relative in-place density. The average of the results of the pair of cores from each location will be expressed as the percent of relative density. All results will be reported to the tenth of one percent (0.1).

1.15.3.2.8. The approximate mix quantity represented by each sub-lot is 600 tons. Additional locations and tests may be required. The quantity represented by 5 tests or approximately 3000 tons of mix constitutes a lot whenever production schedules and material continuity permit. A lot represented by 3 to 7 consecutive random sub-lots will be established when there are short production runs (such as urban environments), significant material changes, or other unusual characteristics of the work.

1.15.3.2.9. All costs of furnishing the cores will be considered incidental to the Commercial Plant Mix bid item and no separate measurement or payment will be made.

1.15.3.2.10. Plant mix surfacing is evaluated for density on a lot-by-lot basis under Subsection 105.03.2.

1.16. ENVIRONMENTAL SPECIAL PROVISIONS

1.16.1. Protection of Aquatic Resources [208]
