Preparation of Existing Pavement. Grass and other vegetation shall be removed from the edge of the existing pavement to prevent contamination of the pulverized bituminous material during the milling operation.

The existing pavement shall be milled to the required depth and width as indicated on the plans.

Recycling shall be in a manner that does not disturb the underlying material in the existing roadway. The milling operation shall be conducted so that the amount of fines occurring along the vertical faces of the cut will not prevent bonding of the cold recycled materials. The pulverized bituminous material shall be processed to the required gradation specified, if the max gradation is exceeded, operations will be stopped until adequate adjustments are made. When a paving fabric is encountered during the CIR operation, the Contractor shall make the necessary adjustments in equipment or operations so that at least 90 percent of the shredded fabric in the recycled material is no more than 5 sq. in. (3200 sq. mm). Additionally, no fabric piece shall have any dimension exceeding a length of 4 in. (100 mm). These changes may include, but not be limited to, adjusting the milling rate or screens in order to obtain a recycled material meeting specification requirements. The Contractor shall be required to waste material containing over-sized pieces of paving fabric as directed by the Engineer. When the Contractor is aware that paving fabric exists, such as indicated on the plans, the Contractor will not receive additional payment. However, if the Contractor is not made aware of the paving fabric, then the Contractor shall receive additional payment for any necessary adjustments in equipment and operations.

Spreading Cement. If cement is required in the mix design, cement shall be spread over the existing pavement prior to the mixing operation. The spreading shall be done in a manner to minimize dusting. The mixing operation shall start within a half an hour of the dry cement being spread.

Mixing Operation. The pulverized material shall be processed through a mixing unit capable of combining the pulverized material, emulsified asphalt, water, and any additives to produce a homogeneous recycled mixture. The emulsified asphalt shall be incorporated into the pulverized bituminous material at the initial rate determined by the mix design(s) and approved by the Engineer. Sampling and mix design may determine different levels of emulsified asphalt at various portions of the project.

Section (5,11)RS-4;114RS-6;(4-BR)BRR

Spreading and Finishing. The recycled material shall be spread using a self-propelled paver. The material shall be transferred to the self-propelled paver via integral conveyor, or a pick-up machine shall be used to transfer the windrowed recycled material into the paver. The pick-up machine must be within 150 ft. (45 m) of the mixing unit. The recycled material shall be spread by a spreading and finishing machine in one continuous pass, without segregation, and to the lines and grades established by the Engineer.

Compaction. The compacted recycled material shall be at a thickness of 2.5 in. to 5.0 in.

(63 mm to 125 mm). The recycled material shall be compacted according to the following.

(a) The effective rolling distance behind the spreading and finishing machine shall not exceed 150 feet. Rolling shall start no more than 30 minutes behind the paver. When possible, rolling shall not be started or stopped on uncompacted materials but with rolling patterns established so that they begin or end on previously compacted material.

(b) The breakdown roller shall be a steel wheel tandem or vibratory roller in either static or dynamic mode. Dynamic mode shall only be used if it is shown to not damage the mixture.

(c) Growth Curve. Rolling patterns shall be developed using growth curves. The Contractor shall perform a growth curve within the first 500 ft of mixture placed each day. The Contractor shall perform additional growth curves during the day if placement begins on a different lift or if mixture emulsion content changes by 0.5% or more. A new growth curve shall be performed if breakdown roller equipment changes.

The growth curve, consisting of a plot of lb./cu. ft. (kg/cu. m) versus the number of passes with the project breakdown roller, shall be developed. Roller speed during the growth curve development shall be the same as the normal compaction operation. The curve shall be established by using a nuclear gage in backscatter mode according to ASTM D 2950. Tests shall be taken after each pass until the highest lb./cu. ft. (kg/ cu. m) is obtained. This value shall be the target density.

(d) Quality Control by the Contractor. The Contractor shall control the compaction process by testing the mix density at random locations as determined according to the QC/QA document, "Determination of Random Density Test Site Locations", and recording the results on forms approved by the Engineer. Testing shall be performed according to ASTM D 2950 in backscatter mode with the same nuclear gage used for growth curve development. Longitudinal joint testing shall be located at each random density location at a distance equal to the lift thickness or a minimum of 2 inches (50 mm) from each pavement edge.

Density shall be between 95.0% and 102.0% of the target density. Unconfined edge density shall be a minimum of 93.0% of the target density. All density test results shall be reported to the Engineer prior to the start of the next day’s production. The Engineer shall be immediately notified of any failing tests and subsequent remedial action.

Section (5,11)RS-4;114RS-6;(4-BR)BRR

(e) Quality Assurance by the Engineer. The Engineer will conduct independent assurance density testing with a nuclear gage utilized in conjunction with daily growth curve development.

If the Contractor is not controlling the compaction process and is making no effort to take corrective action, the operation shall stop as directed by the Engineer.

Opening to Traffic. After the completion of compaction of the recycled material, no traffic, including that of the Contractor, shall be permitted on the completed recycled material for at least two hours. After two hours, rolling traffic may be permitted on the recycled material. This time may be adjusted by the Engineer to allow establishment of sufficient cure so traffic will not initiate raveling or permanent deformation. All loose particles that may develop on the pavement surface shall be removed by power brooming.

After opening to traffic, the surface of the recycled pavement shall be maintained in a condition suitable for the safe movement of traffic.

Maintenance. The Contractor shall maintain the recycled pavement in a manner satisfactory to the Engineer until the wearing course has been constructed. Maintenance related to Contractor construction procedures or quality of work, shall not be paid for separately.

Curing. Before placing the specified wearing course, the recycled pavement shall be allowed to cure until the moisture of the material is reduced to 2.5 percent or less. If a rain event occurs between the final cure and wearing course paving operations, additional moisture content testing shall be conducted to verify the moisture content does not exceed 2.5 percent prior to placing the wearing course. Moisture content testing shall be observed by the Engineer and the test samples shall be taken as a representative sample form the entire thickness of the CIR Unless otherwise directed by the Engineer, the specified wearing course shall be placed within two weeks of the recycled pavement final cure.

Section (5,11)RS-4;114RS-6;(4-BR)BRR

(a) Quality Control by the Contractor. The Contractor shall perform or have performed the inspection and tests required to assure conformance to the contract requirements. Control includes the recognition of obvious defects and their immediate correction. This may require increased testing, communication of test results to the job site, modification of operations, suspension of work, or other actions as appropriate.

The Engineer shall be immediately notified of any failing tests and subsequent remedial action. Passing tests shall be reported to the Engineer no later than the start of the next work day.

(b) Quality Assurance by the Engineer. The Engineer will conduct independent assurance tests on split samples taken by the Contractor for quality control testing. In addition, the Engineer will witness the sampling and splitting of these samples and will immediately retain witnessed samples for quality assurance testing. The Engineer will check the yield daily.

(c) Test Methods:

(1) Pulverized Material Sizing and Gradation. A sample shall be obtained after the milling operation is complete and screened using a 1.5 in. (37.5 mm) sieve to determine if meeting the maximum particle size requirement. The mixing operations shall be turned off and samples collected to check the gradation. Gradations shall be performed each day on the millings at field moisture content using the following sieves: 1.5 in. (37.5 mm), 1.0 in. (25 mm), 3/4 in. (19 mm), 1/2 in. (12.5 mm), 3/8 in.

(9.5 mm), No. 4 (4.75 mm), No. 8 (2.36 mm), No. 16 (1.18 mm), and No. 30 (600 µm). The resulting gradation shall be compared to the mix design gradations to determine any necessary changes to emulsion content. The recycling train shall be move back to the beginning of the sample milling section and all processes turned on to complete the recycling process of the material.

Sampling procedures shall generally be in accordance with ASTM D 979 or

AASHTO T 168.

HOT-MIX ASPHALT SURFACE COURSE SURFACE TESTS

Effective: November 1, 2003 Revised January 1, 2007

The Contractor shall provide a person to operate the straight edge in accordance with Article 406.11 of the Standard Specifications and communicate with IDOT Personnel to minimize the surface course bumps. If surface course bumps cannot be removed at this time, IDOT personnel will record the locations and provide deductions as stated in Article 406.11.

PROTECTION OF FRAMES AND LIDS OF UTILITY STRUCTURES

Effective March 6, 1991 Revised January 1, 2007

This work shall consist of protecting frames and lids of utility structures in the pavement after the adjacent hot-mix asphalt surface has been removed to the required depth by cold milling or by hand methods.

After the area has been swept clean and before the lane is opened to traffic, a hot bituminous mixture shall be placed around the casting, flush with its surface and decreasing to a featheredge in a distance of 4 feet (1.2 m) around the entire surface of the casting. Cold mix or milled material will not be permitted. This mixture shall remain in place until the day surfacing operations are undertaken within the immediate area of the structure. Prior to placing the surface course, the temporary hot-mix asphalt mixture shall be removed and disposed of by the Contractor as specified in Article 202.03 of the Standard Specifications.

The temporary tapers and their removal shall be considered included in the contract unit price per Square Meter (Square Yard) for HOT-MIX ASPHALT SURFACE REMOVAL of the depth specified, and no additional compensation will be allowed.

HOT-MIX ASPHALT SURFACE REMOVAL, 1.5", 2.0", 3.75" & VARIABLE DEPTH

Effective: March 1, 1993 Revised: January 1, 2022

Description: This work shall consist of removing a portion of the existing hot-mix asphalt concrete surface course in accordance with the applicable portions of Section 440 and 1101 of the Standard Specifications, this special provision, details in the plans and as directed by the Engineer. The cold milled salvaged aggregate resulting from this operation shall become the property of the Contractor.

Section (5,11)RS-4;114RS-6;(4-BR)BRR

Equipment: The machine used for milling and planing shall be a self-propelled grinding machine having a minimum 12' (3.6 m) wide drum at least 28" (710 mm) in diameter. When a milling width in excess of 12' is required and the Contractor’s milling machine is less than the required width shown in the plans, the remaining area shall be milled with a machine capable of meeting the requirements of this special provision. Milling attachments used with skid steer tractors will not be allowed for longitudinal areas to mill additional widths.

When the teeth become worn so that they do not produce a uniform surface texture, they shall all be changed at the same time (as a unit). Occasionally, individual teeth may be changed if they lock up or break, but this method shall not be used to avoid changing the set of teeth as a unit.

Occasional gouges, due to deteriorated pavement condition, or separation of lifts will not be cause to replace all teeth. The Engineer will be the sole judge of the cause of the pavement gouging and the corrective work required. Corrective work due to negligence or poor workmanship shall be at the Contractor’s expense.

The moldboard is critical in obtaining the desired surface texture.
