601.11 SURFACE TOLERANCE REQUIREMENTS (LONGITUDINAL).

(a) General: The pavement travel lanes will be tested using an

approved Ames California Type 25-Foot (7.5-m) Profilograph over each wheel path of each lane except that the outside wheel path will not be tested on projects which are classified in Table 1 as Category III projects and which have catch basins and curb along the outside edge of the pavement. The resulting profile trace will be evaluated to determine the location of high points (bumps) in excess of specification limits and to determine the pavement's Average Profile Index. The Average Profile Index is defined as the arithmetical average of the Profile Indexes of the wheel paths for each test section or lot of the travel lanes.

Associated pavements (acceleration lanes, deceleration lanes,

continuous turn lanes and ramps) will be tested using the profilograph over the centerline of each lane or ramp. The resulting profile trace will be evaluated to determine the location of high points (bumps) in excess of specification limits.

Shoulders, turnouts, parking areas, crossovers and the 25-foot (7.5-m) areas of new travel lanes in tie-in areas shall be tested with an approved 10-foot (3.0-m) metal static straightedge.

The operation of the profilograph, including evaluation of the profile trace, determination of the Profile Index for each wheel path in each travel lane, calculation of the Average Profile Index for each roadway and determination of high points (bumps) in excess of specification limits shall be in accordance with DOTD TR 641. The operation of the profilograph and evaluation of the profile trace shall be by trained, qualified personnel who have successfully completed the Department's training and evaluation program.

The Blanking Band Template for determining the Profile Index shall be 0.2 inch (5 mm). The Bump Template for determining high points (bumps) in excess of specification limits shall be 0.3 inch in 25 feet (7.5 mm in 7.5 m) or less for Category I or II in Table I or 0.4-inch in 25 feet (10.0 mm in 7.5 m) or less for Category III in Table 1. The pavement profile determination will terminate approximately 25 feet (7.5 m) from each bridge approach slab or existing pavement that is joined by new pavement constructed under these specifications. Obviously deficient areas, as determined by the engineer, shall be corrected before any profilograph testing is performed.

(b) Requirements: Surface finish testing will be conducted in the longitudinal direction. Deficiencies shall be isolated in both the

longitudinal and transverse direction. All pavement travel lanes and

associated pavements, regardless of design speeds or paving operations,

with surface deviations represented by high points (bumps) in excess of 0.3 inch in 25 feet (7.5 mm in 7.5 m ) or less for Category I or II or 0.4 inch in 25 feet (10.0 mm in 7.5 m) or less for Category III shall be corrected.

A report as required in DOTD TR 641 of each profile trace performed by the contractor shall be supplied to the engineer for review.

(1) Design Speed Greater than 45 MPH (70 km/h): For pavements with design speeds greater than 45 mph (70 km/h) , the contractor shall furnish paving equipment and employ methods that produce a riding surface having an Average Profile Index of not more than 6.0 inches per mile (94.5 mm/km) per lot.

(2) Urban Areas Using Continuous Paving Operations: For urban areas using continuous paving operations with design speeds 45 mph (70 km/h) or less, the contractor shall furnish paving equipment and employ methods that produce a riding surface having an Average Profile Index of not more than 12.0 inches per mile per lot [189.0 (mm/km)/lot].

(3) Urban Areas Not Using Continuous Paving Operations: For

urban areas not using continuous operations (such as: areas with catch

basins, manholes, crossovers, driveways, curb and gutter sections, and

split-slab construction) with design speeds 45 mph (70 km/h) or less, the contractor shall furnish paving equipment and employ methods that produce a riding surface having an Average Profile Index of not more than 20.0 inches per mile per lot [315.5 (mm/km)/lot].

(4) Tie-in Areas, Shoulders, Turnouts, Parking Areas, and

Crossovers: For pavement tie-in areas, shoulders, turnouts, parking areas, and crossovers, the contractor shall furnish equipment and employ methods that produce an acceptable riding surface. Pavement tie-in areas with surface deviations in excess of 1/4-inch in 10 feet (5 mm in 3.0 m) shall be corrected. Pavement shoulders, turnouts, parking areas, and crossovers with surface deviations in excess of 1/2-inch in 10 feet (15 mm in 3.0 m

shall be corrected.

(c) Equipment: The profilograph used for daily paving quality

control and to identify surface areas requiring corrective actions shall consist of an approved Ames California Type 25-Foot (7.5 m) Profilograph furnished, calibrated and operated in accordance with DOTD TR 641 by the contractor.

The profilograph used for surface tolerance acceptance and to

determine surface finish payment adjustments shall consist of an approved Ames California Type 25-Foot (7.5 m) Profilograph furnished, calibrated and operated in accordance with DOTD TR 641 by the Department.

The pavement profile is recorded by the profilograph at a scale of 1:1 vertically and 1:300 [1 inch equals 25 feet (25 mm equals 7.5 m)]

longitudinally.

An approved 10-foot (3.0 m) metal static straightedge shall be

furnished by the contractor for both quality control and acceptance surface tolerance testing of tie-in areas, shoulders, and turnouts, parking areas, and crossovers.

(d) Quality Control Surface Testing: The contractor shall perform quality control surface testing to ensure his paving and finishing operations are producing pavements meeting the requirements for all pavement types listed under the heading. The testing shall be performed using the equipment and at intervals listed under each pavement type.

(1) Pavement Travel Lanes:

During the start up of initial paving operations or after a shut down period initial surface testing shall be performed by the contractor with a profilograph as soon as the concrete has cured sufficiently to allow testing. The purpose of this initial testing is to aid the contractor and the Department in evaluating the paving operations and equipment. The results from this testing shall be furnished to the engineer prior to proceeding with paving operations. If initial testing and evaluation indicates that the average profile index exceeds the minimum requirements given in Table 1 for payment, paving operations shall be suspended until the contractor makes alterations to the paving and finishing operation in order to produce pavements within these limits. The contractor shall continue initial surface testing and make changes to his paving operations until he has demonstrated that he can pour pavements within surface tolerance limits. After initial surface testing has demonstrated that paving operations and pavement smoothness are acceptable, the contractor

shall proceed with regular paving operations and the contractor shall test each days paving with the profilograph no later than during the first work day following placement of the pavement. If the contractor fails to meet the minimum requirements given in Table 1 during regular paving operations, work shall be stopped and alterations to the paving and finishing operation shall be made by the contractor before paving operations can continue. The contractor shall also perform surface testing at the time interval specified for initial surface testing until the engineer is satisfied that the pavement is meeting minimum surface tolerance requirements.

Areas with high points (bumps) in excess of the requirements given in Heading (b), shall be isolated both longitudinally and transversely and corrected by the contractor for the full longitudinal and transverse extent of their occurrence in accordance with Heading (d)(5). Additional profiles

as necessary shall be taken by the contractor to define the limits of all out-of-tolerance pavement requiring correction.

After correcting all individual deviations in excess of the

requirements in Heading (b), additional corrective action shall be made by the contractor as necessary to reduce the Average Profile Index to the minimum requirements given in Table 1. Corrections shall be made in accordance with Heading (d)(5).

On those areas where corrective action is taken, the pavement shall be reprofiled as many times as necessary by the contractor to verify that corrections have produced an Average Profile Index conforming to the minimum requirements given in Table 1 and that the surface deviations in excess of the requirement given in Heading (b), have been corrected.

(2) Associated Pavement: .

During the start up of initial paving operations or after a shut down period, initial surface testing shall be performed by the contractor with a profilograph as soon as the concrete has cured sufficiently to allow testing. The purpose of this initial testing is to aid the contractor and the Department in evaluating the paving operations and equipment. The results from this testing shall be furnished to the engineer prior to proceeding with paving operations. If initial testing and evaluation indicates that there are excessive high points (bumps) in excess of the requirements given in Heading (b), the contractor shall stop and alter paving operations to reduce or eliminate the number of high points (bumps) in excess of specification limits. After initial surface testing has demonstrated that paving operations and pavement smoothness are acceptable, the contractor shall proceed with regular paving operations, and the pavement shall be tested with a profilograph after paving operations for the associated pavement have been completed.

High points (bumps) having deviations in excess of the requirements given in Heading (b) shall be isolated and corrected by the contractor for the full longitudinal and transverse extent of their occurrence in accordance with Heading (d)(5). Verification of the required correction by reprofiling shall be conducted by the contractor.

(3) Shoulders, Turnouts, Parking Areas, and Crossovers:

During the start up of initial paving operations, or after a shut down period, initial surface testing shall be performed by the contractor with an approved 10 feet (3.0 m) metal static straight edge as soon as the concrete has cured sufficiently to allow testing. The purpose of this initial testing is to aid the contractor and the Department in evaluating the paving operation and equipment. The results from this testing shall be furnished to the engineer prior to proceeding with paving operations. If initial testing and evaluation indicates surface deviations in excess of 1/2 inch in 10 feet (15 mm in 3.0 m), the contractor shall stop and alter paving operations to produce pavement with surface deviations of 1/2 inch or less in 10 feet (15 mm or less in 3.0 m). After initial surface testing has demonstrated that paving operations and pavement smoothness are

acceptable, the contractor shall proceed with regular paving operations. The pavement shall be tested with a 10 feet (3.0 m) metal

straight edge after paving operations for this pavement type have been

completed.

Surface deviations in excess of 1/2 inch in 10 feet (15 mm in 3.0m) shall be isolated and corrected by the contractor for the full longitudinal and transverse extent of their occurrence in accordance with Heading (d)(5).

(4) Tie-in Areas: Initial surface testing will not be

required for tie-in areas, however, the contractor shall alter his paving operations if the surface tolerance at the tie-in is unacceptable to the engineer.

The surface of the 25 feet (7.5 m) areas of pavement in tie-in areas which are not tested with the profilograph shall be tested after completion in each wheel path for its entire length with a 10 feet (3.0 m) metal static straight edge. The joint between the new and existing pavement or approach slab shall also be tested with the straight edge placed longitudinally across the joint in each wheel path. Surface deviations in excess of 1/4 inch in 10 feet (6 mm in 3.0 m) shall be isolated and corrected by the contractor for the full longitudinal and transverse extent of their occurrence in accordance with Heading (d)(5).

(5) Corrections: Corrections shall be made using an approved profiling device or by removing and replacing the pavement as directed. The use of bush hammers or other impact devices will not be permitted. In cases where corrections are made using an approved profiling device the contractor shall reestablish transverse grooving by sawing to provide a uniform texture conforming to Subsection 601.08(h). Corrective work will be at no direct pay and shall be completed prior to determination of pavement or shoulder thickness.

(e) Acceptance Surface Testing:

(1) Travel Lanes:. After corrective work and verification

within a lot has been completed by the contractor in conformance with these specifications, each lot will be tested for surface tolerance acceptance. The acceptance testing for surface tolerance will be performed by the Department unless the contractor requests to do the testing.
