338-3 Responsible Party.
Prior to any value added asphalt pavement being placed on the project, the Contractor shall designate a Responsible Party to accept responsibility for maintaining the value added asphalt pavement, when remedial work is required. When the scope of the asphalt work is only milling and resurfacing, a nd there is no construction of the embankment, subgrade or base below the pavement included in the Contract, the Responsible Party may be either the Contractor or the Department approved subcontractor performing the value added asphalt pavement work. When the construction of the embankment, subgrade or base below the pavement is included in the Contract, in addition to the construction of the asphalt concrete structural course and asphalt concrete friction course, the Contractor shall be considered as the Responsible Party. When the Responsible Party is a subcontractor, the subcontractor must be pre -qualified with the Department in the category of asphalt, and such designation must be made to the Department by the Contractor. The proposed subcontractor must execute and submit to the Department a form, provided by the Department, prior to or concurrent with the Contractor’s request to sublet any value added asphalt pavement work, stipulating that the subcontractor assumes all responsibility as the Responsible Party for the value added asphalt pavement within the three-year warranty period. Failure to timely designate the Responsible Party will result in the Contractor being the Responsible Party unless otherwise agreed to in writing by the Department. Upon final acceptance of the Contract in accordance with 5 -11, the Contractor’s responsibility for maintenance of all the work or facilities within the project limits of the Contract will terminate in accordance with 5 -11; with the sole excepti on that the obligations set FY 2023-24 Return to Table of Contents forth in this Section for value added asphalt pavement will continue thereafter to be the responsibility of the Responsible Party as otherwise provided in this Section.

The Statewide Dispu tes Review Board in effect for this Contract will resolve any and all disputes that may arise involving administration and enforcement of this Specification. The Responsible Party and the Department acknowledge that use of the Statewide Disputes Review Board is required, and the determinations of the Statewide Disputes Review Board for disputes arising out of this Specification will be binding on both the Responsible Party and the Department, with no right of appeal by either party. Meet the requirements o f 8-3.
338-5 Pavement Evaluation and Remedial Work.
338-5.1 General: The Department’s Pavement Condition Survey Program, along with
observations by the Engineer, will be used as the basis for determining the extent and the magnitude of the pavement distre sses occurring on the project. In the event the level of distress exceeds any of the threshold values defined below, remedial work as described in 338 -5.5 by the Responsible Party will be required. The Department will monitor the pavement for distresses and may require remedial action at any time. For evaluation purposes, the project will be subdivided into LOTs of 0.1 mile per lane. When the segment is less than 0.1 mile, the segment will be called a partial LOT. For purposes of threshold values and rem edial work, partial lots and lots will be treated as lots. The Department may conduct a Pavement Condition Survey of the value added pavement following the final acceptance of the project, and at intermediate times throughout the warranty period with findi ngs provided when considered by the Department to be the obligation of the Responsible Party . The final survey, if determined by the Engineer to be necessary, will be conducted before the end of the warranty period with results provided to the Responsib le Party for those conditions exceeding contract threshold values requiring remedial action that the Department believes to be an obligation of the Responsible Party. The Department will be responsible for all costs associated with the surveys. If the survey findings, intermediate or final, are to be disputed by the Responsible Party, written notification must be submitted to the Engineer within 30 calendar days of the date of receipt of the information from the Department. During the warranty period, the Responsible Party may monitor the project using nondestructive methods and may participate with the Department in the Pavement Condition Surveys upon request. The Responsible Party shall not conduct any coring, milling or other destructive meth ods without prior approval by the Engineer.

2.Settlement/Depression: Depth of the settlement/depression to be determined by a 6-foot manual straightedge.
338-5.5 Remedial Work: The Responsible Party will perform all necessary remedial
work described within this Section at no cost to the Departm ent. If the pavement distresses exceed threshold values and it is determined that the cause of the distress is due to the embankment, subgrade, base or other activities performed by the Contractor, the Responsible Party will be responsible for performing a ll remedial work associated with the pavement distress. Should an impasse develop in any regard as to the need for remedial work or the extent required, the Statewide Disputes Review Board will render a final decision by majority vote. Remedial work will not be required if any one of the following conditions is found to apply:
a.Determination that the pavement thickness design as provided by the Department is deficient. The Department will make available a copy of the original pavement thickness desig n package and design traffic report to the Responsible Party upon request. The Responsible Party is responsible for performing all remedial work associated with the pavement distress if the pavement design is provided by the Contractor.
b.Determination that the Accumulated ESALs (Number of 18 Kip Equivalent Single Axle Loads in the design lane) has increased by 25% or more than the Accumulated ESALs used by the Department for design purposes for the warranty period for the pavement design life. In calcu lating ESALs, the average annual daily traffic (AADT) will be obtained from the Department’s traffic count data and the T24 ( percent heavy trucks during a 24 hour period) will be obtained from the Department’s traffic classification survey data.
c.Determination that the deficiency was due to the failure of the existing underlying layers that were not part of the Contract work.
d.Determination that the deficiency was the responsibility of a third party or its actions, unless the third party was p erforming work included in the Contract.
e.Determination that raveling of open -graded friction course (FC -5) in a turn lane, turn out, or median cross over was caused by turning movements and not a materials or construction issue. If a measured distr ess value indicates remedial action is required per Table 338-1, Table 338-2 and/or Table 338-3, the Responsible Party must begin remedial work within 45 calendar days of notification by the Department or a ruling of the Statewide Disputes Review Board. The Disputes Review Board will determine the allowable duration for the completion of the remedi al work, but not to exceed six months. FY 2023-24 Return to Table of Contents In the event remedial action is necessary and forensic information is required to determine the source of the distress, the Department may core and/or trench the pavement. The Responsible Party will not be responsib le for damages to the pavement as a result of any forensic activities conducted by the Department. As applicable to distress criteria for rutting, ride and cracking for Category 1 and Category 2 pavements, when two LOTs requiring remedial action are not separated by three or more LOTs not requiring remedial action, the remedial work shall be required for the total length of all such contiguous LOTs, including the intermediate LOTs not requiring remedial action. Additionally, for Category 1 and Category 2 pavements, where such areas of remedial action are required due to raveling, slippage or bleeding are separated by less than 1,000 feet, the remedial work will be required for the entire area contiguous to the distressed areas, including intermediate are as otherwise requiring no remedial action. The Responsible Party has the first option to perform all remedial work that is determined by the Department to be their responsibility. If, in the opinion of the Engineer, the problem poses an immediate danger to the traveling public and the Responsible Party cannot provide temporary mitigation for the defect within 4 hours of written notification and restore the pavement to its original design condition within 72 hours of written notification, the Engineer has the authority to have the remedial work performed by other forces. Temporary mitigation includes the use of traffic control systems such as barricades, drums, or other approved devices to secure the area including lane closures if necessary, and constructi ng temporary repairs making it safe for the roadway user until the defect can be restored to its original design condition. The Responsible Party is responsible for all incurred costs of the work performed by other forces should the problem (remedial work) be determined to be the responsibility of the Responsible Party. Remedial work performed by other forces does not alter any of the requirements, responsibilities or obligations of the Responsible Party. The Responsible Party must complete all remedial w ork to the satisfaction of the Engineer. Any disputes regarding the adequacy of the remedial work will be resolved by the Statewide Disputes Review Board. Approval of remedial work does not relieve the Responsible Party from continuing responsibility under the provisions of this Specification. Notify the Engineer in writing prior to beginning any remedial work. Meet the requirements of the Specifications when performing any remedial work. P erform all signing and traffic control in accordance with the curr ent edition of the Department’s Standard Plans. Provide maintenance of traffic during remedial work at no additional cost to the Department. Lane closure restrictions listed in the original Contract will apply to remedial work. Written requests to obtain p ermission for lane closures for either forensic investigation or remedial work must be made to the Engineer 48 hours in advance of any lane closures. Do not perform any lane closures until written permission is given by the Engineer . If remedial work nec essitates a corrective action to overlying asphalt layers, pavement markings, signal loops, adjacent lanes, roadway shoulders, or other affected Contract work, perform these corrective actions using similar products at no additional cost to the Department.
338-6 Responsible Party’s Failure to Perform.
Should the Responsible Party fail to timely submit any dispute to the Statewide Disputes Review Board, fail to satisfactorily perform any remedial work, or fail to compensate the Department for any remedial w ork performed by the Department and determined to be the Responsible Party’s responsibility in accordance with this Specification, the Department will FY 2023-24 Return to Table of Contents suspend, revoke or deny the Responsible Party’s certificate of qualification under the terms of Section 337.16(d)(2), Florida Statutes, for a minimum of six months or until the remedial work has been satisfactorily performed (or full and complete payment for remedial work performed by others made to the Department), whichever is longer. Should the Responsible Party choose to challenge the Department’s notification of intent for suspension, revocation or denial of qualification and the Department’s action is upheld, the Responsible Party will have its qualification suspended for an additional minimum of six months. The remedial work is not an obligation of the Contractor’s bond required by Section 337.18, Florida Statutes. FY 2023-24 Return to Table of Contents SECTION 339 MISCELLANEOUS ASPHALT PAVEMENT
339-1 Description.
Construct asphalt pavement in areas where vehicular traffic does not travel, such as pavement under guardrail, bicycle paths, median pavement, sidewalks, etc. Also, chemically treat the underlying soil to prevent plant growth.
339-2 Materials.
For the pavement, use any plant -mixed hot bituminous mixture meeting the requirements of a mix design verified by the Engineer, except do not use open -graded friction course (F C-5). For bicycle paths, use a mixture that produces a finished pavement which will not distort or mar under bicycle or mower wheel loads. In general, the Engineer will accept the mixture on the basis of visual inspection with no further testing required.
339-3 Foundation and Soil Treatment.
Shape the soil in areas where pavement is to be constructed, to a surface true to the lines, grades and typical sections shown in the Plans. Compact the soil to a firm state. Immediately before placing the pavement, uniformly apply a pre -emergent herbicide in accordance with the requirements of 7 -1.7, to the foundation soil. Ensure that the herbicide carries an approved label for use under paved surfaces, and that herbicide is applied in accordance with directions on the label. Prevent damage to any adjacent vegetation during herbicide application. Replace, at no expense to the Department, any plants damaged as the result of soil treatment outside designated areas.
339-4 Placing Mixture.
Uniformly place the hot bitum inous mixture by machine or hand methods at the rate of spread or dimensions indicated in the Plans or as otherwise directed by the Engineer. If posts are to be constructed within the pavement area, the Contractor may cut holes for installation through the completed pavement. After completing installation of posts and compaction of the backfill material, patch the area around each post with fresh hot bituminous mixture. If directed by the Engineer, place miscellaneous asphalt pavement prior to placement of the final surface course.
339-5 Compacting Mixture.
Uniformly compact the hot bituminous mixture with lightweight rollers or vibratory compactors as directed by the Engineer. The Contractor may use hand tamps for compaction in areas which are inaccessible to other compaction equipment. The Engineer will not require a specific density.
339-6 Surface Requirements.
Provide a finished surface that is reasonably smooth, of uniform texture, and shaped so as to drain without ponding of water. FY 2023-24 Return to Table of Contents
