501.10 SURFACE TOLERANCE REQUIREMENTS: Acceptance testing for surface

tolerance as outlined herein and in Table 1 of this section will be the

responsibility of the Department. Quality control testing will be the

responsibility of the contractor. The contractor shall provide an approved 25-Foot (7.5 meter) California-Type Ames Profilograph calibrated and operated in accordance with DOTD TR 641 for longitudinal surface tolerance quality control testing. The contractor may elect to use alternate or automated profilographs in lieu of the standard California Type Ames Profilograph. The profilograph must be approved by the Materials and Testing Engineer. The results generated by alternate profilograph models must correlate to results generated by the California Type Ames Profilograph to within 1.0 inch/mile (15 mm/km) for pavement surfaces which are up to 15 inches/mile (240 mm/km) in roughness. Additionally, alternate models must demonstrate repeatability to within 1.0 inch/mile (15 mm/km) when testing pavements up to 15 inches/mile (240 mm/km) in roughness. The number of test runs for this determination will be at least three. Alternate profilographs shall allow for field calibration using vertical deflection standards and provide a verifiable method of horizontal calibration. Automated models must meet all standards required of manual models. Approval of manual and automated models will be based on comparison to the Departmental standard California Type Ames Profilograph. Manufacturers shall make a model of a proposed alternate profilograph available to the Department for at least 60 days for evaluation. Additionally, the Department may require comparative data prior to beginning the evaluation process. Automated profilographs will be approved for contractors Quality Control testing only. The profilograph used for

longitudinal surface tolerance acceptance and to determine surface

tolerance payment adjustments will consist of an approved 25-Foot (7.5

meter) California-Type Ames Profilograph (strikethrough: furnished,)

calibrated (strikethrough: and operated) by the Department in accordance with DOTD TR 641. An approved minimum 10-foot (3.0 m) metal static straightedge shall be furnished by the contractor for transverse and longitudinal surface tolerance acceptance testing.

The operation of the profilograph including evaluation of the profile trace, determination of the Profile Index, calculation of the Average Profile Index and the determination of high points (bumps) in excess of specification limits shall be accomplished by a trained, authorized technician who has successfully completed the Department's training and evaluation program.

Surface tolerance testing will be required on roadway travel lanes and airport wearing and binder courses, and shoulder and parking area wearing courses. For the purposes of surface tolerance requirements, the wearing course is defined as the last lift placed. The binder course is defined as the last lift placed prior to the wearing course.

Other lifts on which additional asphaltic concrete is to be placed

shall be finished so that succeeding courses will meet the requirements in this section. Base courses on which Portland cement concrete pavement is to be placed shall be finished so that the Portland cement concrete pavement will meet the requirements of Section 601.

(a) Longitudinal Surface Tolerance: (strikethrough: The finished

surface will be tested in the longitudinal direction for conformance to the surface tolerance requirements listed in this Section. When testing for roadway and airport wearing and binder courses using the profilograph, one path in each paving strip in a lot will be selected at random in accordance with the Materials Sampling Manual. For shoulders (minimum 10 feet wide) and parking areas, testing of the wearing course in one random path will be required. The entire lot will be tested and shall meet the following requirements:) The finished surface will be tested in the longitudinal direction for conformance to the surface tolerance requirements listed in this section. When testing for roadway travel lanes and airport wearing and binder courses using the profilograph, one path in each paving strip in a lot will be selected for Quality Control and Acceptance Testing. The test path selected will be the inside wheel path of each paving strip adjacent to the centerline.(strikethrough: For parking areas, testing of the wearing course in one random path will be required). The entire lot

will be tested and shall meet the following requirements:

(1) Quality Control Testing: (strikethrough: The contractor

shall test the pavement no later than during the first work day following placement but in no case longer than 14 calendar days. Quality Control testing using a profilograph shall be required on roadway and airport wearing and binder courses, shoulders (minimum 10 feet wide) and parking area wearing courses.) The contractor shall test the pavement no later than during the first work day following placement but in no case longer than 14 calendar days. Quality Control testing using a profilograph shall be required on roadway travel lanes and airport wearing and binder courses. (strikethrough: , and parking area wearing courses.)

When quality control testing establishes that the surface tolerance is deficient, the contractor will immediately suspend paving operations. Paving operations will not be allowed to resume until appropriate corrections have been made and a test section successfully placed with acceptable surface tolerance. This test section shall consist of a maximum of 500 tons (450 Mg) of asphaltic concrete which is to be placed in a continuous operation.

The contractor shall control the paving operation and frequently test the surface to maintain the quality of the finished surface. The

contractor shall profile, correct and reprofile as many times as necessary to verify that specification requirements have been met before notifying the engineer a lot is being submitted for acceptance.

The contractor shall correct deficiencies, determined during quality control testing in accordance with Heading (e) at no direct pay. Once these corrections have been completed and the surface tolerance requirements listed herein and in Table 1 have been met, the contractor shall provide the engineer the reports required in DOTD TR 641 with notification that the lot is ready for acceptance testing.

a. Roadway and Airport Wearing:

1. Multi-lift New Construction and Overlays More Than Two Lifts: Pavement with high points (bumps) in excess of 0.3 inch in 25 feet (7.5 mm in 7.5 m ) (1:1000) or less shall be corrected and the lot retested. The Average Profile Index shall not be more than 3.0 inches per mile (47 mm/km) per lot.

(strikethrough: 2. Single-lift Construction Over Cold Planed Surfaces and Two-Lift Overlays: )(strikethrough: Pavement with high points (bumps) in excess of 0.3 inch in 25 feet or less shall be corrected and the lot retested. The Average Profile Index shall be not more than 5.0 inches per mile per lot.) 2. One or Two Lift Overlays Over Cold Planed

Surfaces and Two-Lift Overlays: Pavements with high points (bumps) in

excess of 0.3 inch in 25 feet (7.5 mm in 7.5 m) or less shall be corrected (strikethrough: and the lot retested). The Average Profile Index shall not be more than 5.0 inches per mile per lot ((strikethrough: 78.5) 79 mm/km per lot).

In urban areas, the Project Engineer will review the profile trace

obtained for each binder and wearing course on a per lot basis. Those

areas out of specification which have been, in the opinion of the Project Engineer, created by conditions beyond the control of the contractor may be isolated and excluded from the calculations of the Average Profile Index. These exceptions may involve areas in curb and gutter sections which require the adjustment of cross-slope in order to maintain adequate drainage, manholes, catch basins, valve and junction boxes, intersections, street or other structures located in the roadway, or areas that have been removed (whipped out) by traffic after cold planing, which cause abrupt deviations in the profile trace. High points (bumps) in excess of 0.4 inch in 25 feet (10 mm in 7.5 m) shall be corrected, unless in the opinion of the Project Engineer, these high points do not cause detriment or damage to the roadway section or rideability. These high points, then may be allowed to remain with a $500.00 per bump rebate. In all cases, the contractor has the option to grind the bumps to meet the specifications.

3. Single-lift Overlays Over Existing Surfaces:

Pavement with high points (bumps) in excess of 0.3 inch in 25 feet (7.5 mm in 7.5 m) (1:1000) or less shall be corrected and the lot retested. The Average Profile Index shall be not more than (strikethrough: 8.0) 12.0 inches per mile ((strikethrough: 126) 189 mm/km) per lot.

(strikethrough: c. Shoulders (less than 10 feet wide),

turnouts, crossovers, and roadway sections less than 100 feet in length: ) (strikethrough: For shoulders (less than 10 feet wide), turnouts, crossovers and roadway sections less than 100 feet in length, the wearing course shall be tested with an approved 10-foot metal static straightedge and the surface deviations shall not exceed 1/2 inch. Areas with surface deviations in excess of 1/2 inch shall be isolated and corrected by the contractor in accordance with Heading (e).)

c. Shoulders , Turnouts, Crossovers, Detour Roads, Parking Areas, and Roadway Sections Less Than (strikethrough: 100) 500 Feet ( (strikethrough: 30) 150 m) in Length: For shoulders, turnouts, crossovers, detour roads and roadway sections less than (strikethrough: 100) 500 feet ( (strikethrough: 30) 150 m) in length, the wearing course shall be tested with an approved 10-foot (3-meter) metal static straightedge and the surface deviations shall not exceed 1/2 inch (15 mm).

(2) Acceptance Testing: (strikethrough: After corrective work and quality control testing within a lot has been completed by the

contractor in conformance with these specifications and Table 1, the

Department will evaluate the profile trace from the contractor's quality control tests for all courses. Longitudinal variations in the final wearing course surface will be subject to provisions of Subsection 501.12(b)(2)d. The entire lot will be tested by the Department no later than 14 calendar days after all corrective work is completed by the contractor with the same type of equipment. Test path for acceptance testing will be randomly selected independent of Quality Control test paths in accordance with the Materials Sampling Manual.) After corrective work and quality control testing within a lot has been completed by the contractor in conformance with these specifications and Table 1, the Department will evaluate the profile trace from the contractor's quality control tests for all courses. Longitudinal variations in the final wearing course surface will be subject to provisions of Subsection 501.12(b)(2)d. A DOTD Certified Profilograph Operator or Evaluator shall be present when the contractor conducts the final quality control testing. The contractor will be allowed to evaluate the final quality control trace to determine if any corrective measures are needed to eliminate deficient areas under the direct supervision of the DOTD Certified Profilograph Operator or Evaluator. Upon completion of the contractor's evaluation, the DOTD Inspector will take immediate possession of the final quality control trace to be used for project acceptance. If corrective measures will be required to correct deficiencies, it will be necessary to reprofile only those affected areas, and recompute the profilograph index using the original final trace and the "reroll" traces. All final quality control traces including the "reroll" quality control trace shall be run in the presence of the DOTD Certified Profilograph Operator or Evaluator and the Department will take immediate possession of these traces for evaluation by the DOTD Certified Evaluator. The Department will retain the right to verify the contractor's final quality control trace using the Department's Certified California Type Ames Profilograph.

The test path selected for acceptance testing will be the inside wheel path of each paving strip adjacent to the centerline. (strikethrough: The surface of each shoulder less than 10 feet wide will be tested longitudinally by the engineer at a minimum of one randomly selected location in each 300 linear feet of shoulder using the 10-foot metal static straightedge; areas with surface deviations in excess of ½ inch will be isolated by the engineer and shall be corrected by the contractor in accordance with Heading (e).)

The surface of each shoulder will be tested longitudinally by the engineer at a minimum of one randomly selected location in each 300 linear feet (90 linear meters) of shoulder using the 10-foot (3 m) metal static straightedge; areas with surface deviations in excess of 1/2 inch (15 mm) will be isolated by the engineer and shall be corrected by the contractor in accordance with Heading (e).
