B. Repair or replace curbs, manholes, catch basins, and other construction damaged during pave-ment milling operations.

C. Prepared milled pavement as required to receive new bituminous pavement.



3.3 PREPARATION

A. Existing Pavement: Where new hot mixed bituminous paving abuts existing bituminous pave-ment including repair work, provide straight line, sawing through existing bituminous pavement construction. 1. Perform sawing prior to removing bituminous pavement to be replaced. 2. Refer to joint spacing provisions under Placing the Mix and to patching provisions under

Compacting the Mix for coordination purposes and/or per construction plan details. 3. In areas where sawed lines have become damaged or worn by construction activities, the

contractor shall re-saw straight, clear lines immediately prior to paving.

B. Proof roll prepared base material surface to check for unstable areas in accordance with MDOT Specification for Construction, current edition and/or Section 31 20 00 whichever is more strin-gent including documentation and re-proof rolling as required. Paving work shall begin only af-ter unsuitable areas have been corrected and are ready to receive paving.

C. Remove loose material from compacted base material surface immediately before applying prime coat.

D. Establish and maintain required lines and elevations.

E. Cover the surfaces of curbs, gutters, manholes and other structures on which the asphaltic con-crete mixture will be placed, with a thin, uniform coat of liquid asphalt. Where the asphaltic concrete mixture will be placed against the vertical face of an existing pavement, clean the ver-tical face to remove foreign substances and apply a coating of liquid asphalt at a rate of approx-imately 0.25 gallons per square yard.

3.4 FRAME ADJUSTMENTS

A. Set frames for manholes and other such units, within areas to be paved, to final grade as part of this work. Include existing frames or new frames furnished in other sections of these Specifica-tions.

B. Surround frames set to grade with a ring of compacted hot mixed bituminous base prior to pav-ing. Place bituminous pavement mixture up to 1 inch below top of frame, slope to grade, and compact with hand tamp.

C. Adjust frames as required for paving. Provide temporary closures over openings until comple-tion of rolling operations. Remove closures at completion of work. Set cover frames to grade, flush with surface of adjacent pavement.

3.5 PREPARING THE MIX

A. Plant Equipment and Procedures: Comply with all MDOT specifications and requirements.

B. Aggregate Storage: Keep each component of various-sized combined aggregates in separate stockpiles. Maintain stockpiles so that aggregate sizes will not be intermixed and to prevent ag-gregation.



C. Asphalt Cement Preparation: Heat asphalt cement at mixing plant to a viscosity that can readily be pumped and distributed throughout the hot mixed asphalt mixture. Add asphalt cement binder to aggregate at a temperature between 235 degrees F and 350 degrees F.

D. Aggregate Preparation: Dry aggregate and deliver to mixer at a temperature between 235 de-grees F and 350 degrees F. Maintain the temperature between these limits according to the pen-etration grade and viscosity characteristics of the hot mixed asphalt cement, ambient tempera-ture, and workability of the mixture, while the hot mixed asphalt cement is being added. 1. Dry aggregate to reduce moisture-content and to prevent hot mixed asphalt mixture from

foaming, slumping or segregating during hauling and placing operations.

E. Mixing: Accurately weigh or measure dried aggregates and weigh or meter asphalt cement to comply with job-mix formula requirements. Do not heat asphalt cement above 350 degrees F, at time of introduction into mixer. 1. Mix aggregate and asphalt cement to achieve 90-95 percent of coated particles for base

mixture and 85-90 percent of coated particles for surface mixture.

F. Delivery: Transport hot mixed bituminous paving mixtures from mixing plant to project site in trucks having tight, clean compartments. If required, coat hauling compartment surfaces with a lime-water mixture or a soap or detergent solution to prevent bituminous pavement mixture from sticking. Elevate and drain compartment of excess solution before loading mix. 1. Provide covers over hot mixed bituminous paving mixture when delivering to protect

mixture from weather and to prevent loss of heat. 2. During periods of cool weather or for long-distance deliveries, provide insulation around

entire truck bed surfaces.

3.6 APPLICATION

A. Tack Coat: 1. Apply to contact surfaces of previously constructed asphaltic concrete base courses or

Portland cement concrete and surfaces abutting or projecting into asphaltic concrete or in-to asphaltic concrete pavement.

2. Apply tack coat to asphaltic concrete base course or sand asphalt base course. Apply emulsified asphalt tack coat between each lift or layer of full depth asphaltic concrete and sand asphalt bases and on surface of bases where asphaltic concrete paving will be con-structed.

3. Apply at minimum rate of 0.10 gal per sq. yd of surface. 4. Allow drying until at proper condition to receive paving.

3.7 ASPHALTIC CONCRETE PLACEMENT

A. Place asphaltic concrete mixture on completed compacted subgrade surface, spread, and strike off. Spread mixture at following minimum ambient temperatures: 1. Between 40 and 50 F: Mixture temperature: 285 F 2. Between 50 and 60 F: Mixture temperature: 280 F 3. Higher than 60 F: Mixture temperature: 275 F

B. Whenever possible, spread pavement by finishing machine; however, inaccessible or irregular areas may be placed by hand methods. Spread hot mixture uniformly to required depth with hot shovels and rakes. After spreading, carefully smooth hot mixture to remove segregated coarse



aggregate and rake marks. Rakes and lutes used for hand spreading shall be type designed for use on asphalt mixtures. Do not dump loads faster that they can be properly spread. Workers shall not stand on loose mixture while spreading.

C. Paving Machine Placement: Apply successive lifts of asphaltic concrete in transverse directions with surface course placed parallel to flow of traffic. Place asphaltic paving in typical strips not less than 10'-0" wide. Asphaltic concrete pavement, including base and surface course, shall be placed in two or more equal lifts. Each lift shall be from 1 to 3 inches thick or per MDOT Spec-ification for Construction, current edition.

D. Joints: Make joints between old and new pavements, or between successive days and work in manner that will provide continuous bond between adjoining work. Construction joints shall have same texture, density, and smoothness as other sections of asphaltic concrete course. Clean contact surfaces of joints and apply tack coat.

3.8 ROLLING AND COMPACTION

A. After being spread, mixture shall be compacted by rolling as soon as it will bear the weight of rollers without undue displacement. Number, weight, types of rollers, and sequences of rolling operations shall be such that the required density and surface are consistently attained while the mixture is in workable condition.

B. Compact mixture with hot hand tampers or vibrating plate compactors in areas inaccessible to rollers.

C. Breakdown Rolling: Perform breakdown or initial rolling immediately following rolling of joints and outside edge. Check surface after breakdown rolling and repair displaced areas by loosening and filling with hot material.

D. Second Rolling: Follow breakdown rolling as soon as possible while mixture is hot. Continue second rolling until mixture has been thoroughly compacted as follows: 1. Average Density: 96 percent of reference laboratory density according ASTM D1556,

but not less than 94 percent nor greater than 100 percent.

E. Finish Rolling: Perform finish rolling while mixture is still warm enough for removal of roller marks. Continue rolling until roller marks are eliminated and course has attained maximum density.

F. Patching: Remove and replace paving areas mixed with foreign materials and defective areas. Cut out such areas and fill with fresh, hot asphaltic concrete. Compact by rolling to maximum surface density and smoothness.

G. Protection: After final rolling, do not permit vehicular traffic on pavement until it has cooled and hardened. Erect barricades to protect paving from traffic until mixture has cooled enough not to become marked. Any masked or marred finish surfaces shall be repaired or smoothed.

3.9 JOINTS

A. General



1. Place each asphaltic paving layer as continuous as possible to keep the number of joints to a minimum. Create joints between old and new pavement, between successive days work, and where the mixture has become cold (less than 140 degrees F). Make these joints in such a manner as to create a continuous bond between the old and new pavement construction courses.

2. Offset joint of successive courses by at least 6 inches.

B. Transverse Joints: If placing of material is discontinued or if material in place becomes cold, make a joint running perpendicular to the direction traveled by the paver. Before placement continues, trim the edge of the previously placed pavement to a straight line perpendicular to the paver and cut back to expose an even vertical surface for the full thickness of the course. When placement continues, position the paver on the transverse joint so that sufficient hot mixture will be spread in order to create a joint after rolling that conforms to the required smoothness. If the temperature of the previously placed pavement material drops below 140 degrees F before pav-ing is resumed, give the exposed vertical face a thin coat of liquid asphalt just before paving is continued.

C. Longitudinal Joints: Coat longitudinal joints that are not completed before the previously laid mixture has cooled to a temperature below 140 degrees F, with liquid asphalt just before paving is continued.

3.10 SEAL COAT

A. Apply seal coat over new wearing course if requested by owner and/or if indicated on plans.

B. Allow pavement to cure three weeks minimum. Remove dust and oil to ensure proper adhesion of seal coat to pavement. Persistent or oil films that are not removed by mechanical brushing or scrubbing with detergent and water can be sprayed with primer at not more than 0.01 gallons per sq. yd. Detergent must be thoroughly rinsed off before pavement is sealed.

C. Mix a sand slurry using sealer, sand, and makeup water as recommended by manufacturer.

D. Apply sand slurry evenly and uniformly at a rate of 0.10 to 0.15 gallons per sq. yd.

E. When sand slurry treatment is dry, apply one coat of sealer (without sand) uniformly over entire area at a rate of 0.10 to 0.15 gallons per sq. yd.

3.11 FIELD QUALITY CONTROL

A. Field quality control tests specified herein will be conducted by the Testing Laboratory (TL). The Contractor shall perform additional testing as considered necessary by the Contractor for assurance of quality control. Retesting required as a result of failed initial tests shall be at the Contractor’s expense.

B. Field testing, frequency, and methods may vary as determined by and between the Contractor and the Testing Laboratory.



C. Testing shall be performed on finished surface of each asphalt concrete course for smoothness, using 10'-0" straightedge applied parallel with, and at right angles to centerline of paved area. The following tolerances in 10 ft shall not be exceeded:

Base / Leveling Course Surface: 1/4-inch Wearing Course Surface: 1/8-inch

D. Field density test for in-place materials: 1. Density tests shall be conducted on each core sample taken in accordance with ASTM

D1188 or D2726 as applicable. 2. In-place density tests by nuclear method in accordance with ASTM D2950 shall also be

taken as necessary to assure the specified density is obtained. Nuclear density shall be correlated with ASTM D1188 or D2726.

E. Pavement density will be measured by the Engineer at the time of placement using a nuclear density gauge with the maximum theoretical specific gravity (Gmm) from the job mix formula (JMF) being used as the field control. 92% maximum of the theoretical maximum density (TMD) is required for acceptance.

F. Laboratory Air Void, Marshall Stability, and Flow: Mixture samples shall be taken at least four times for every 2000 tons or 8 hour day and compacted into specimens, using compactive blows (35, 50, or 75) equal to mix design per side with the Marshall hammer as described in AASHTO T 245. Temperature shall be equal to temperature at paving machine with reheating. After compaction, the laboratory air voids of each specimen shall be determined, as well as the Mar-shall stability and flow.

G. Check surface areas as necessary to identify any area that pond water. Remove and replace all unacceptable paving as directed by Engineer.

H. Asphalt Extraction and Aggregate Gradation: Asphalt extraction and gradation of extracted ag-gregate testing shall be performed in accordance with AASHTO TP 53 and ASTM D5444 re-spectively. At least two extraction and two gradation tests shall be taken for each 2000 tons or each day pavement is placed.

I. Areas of deficient paving, including compaction, smoothness, thickness, and asphalt mixture, shall be delineated, removed, and replaced in compliance with Specifications requirements un-less corrected otherwise as directed and approved by the Engineer.

J. The Contractor shall certify in writing that asphalt placement is in accordance with specification requirements.
