DESCRIPTION

This work will be done in accordance with the requirements of Section 305, 501, 902, and 904 of the Michigan Department of Transportation (MDOT) 2020 Standard Specifications for Construction, except as herein specified.

This work shall be accomplished in place and shall consist of blending crushed material with hot asphalt cement at the specified rate and depth, shaping to specified elevation and slope, and compacting to specified density.

MATERIALS

Materials shall meet the following requirements:

Asphalt Cement PG 52-28 Fog Coat SS - 1H

The asphaltic material for stabilizing shall be applied at the rate and temperature (minimum 350° F) as determined by the Engineer, so that the residual bitumen added will be between two (2) and five (5) per cent by weight of the asphaltic material.

EQUIPMENT REQUIREMENTS

1. Compaction Equipment - Rollers. Rollers must meet the requirements as specified under Section 501.03 for rollers, except that combination pneumatic-steel wheel and vibratory rollers will be permitted. A minimum of three (3) rollers in operating condition will be required on the project and shall be of the following types:

Minimum of (2) shall be steel drum vibratory type;

Minimum of (1) shall be pneumatic - tire type.

All rollers are to be approved by the Engineer prior to beginning construction.

2. Stabilizing Equipment - All equipment to be approved by the Engineer prior to beginning construction. The stabilizing plant shall be a single-pass, multi-drum, self-propelled rotary mixer combining a cutter rotor, a blending rotor, and two mixing rotors in the mixing chamber. The mixing chamber shall have a positive depth control to insure a uniform depth of stabilized material and must be capable of loosening the base materials to the depth called for without disturbing the subbase. The stabilizing plant shall add the asphalt in predetermined and accurately metered quantities, while maintaining a constant and fixed rate of forward motion, thoroughly blend the asphalt with the road materials, and spread

Part One - Washington Park the mixture uniformly on the roadway.

A spray bar for distribution of the liquid asphalt shall be mounted inside the mixing chamber and shall have nozzles spaced at increments not to exceed six

(6) inches and shall operate in such a manner that all asphalt will be uniformly applied throughout the mixing chamber at the time of injection. The asphalt additive system shall consist of a positive displacement pump and shall display the temperature, pressure and flow rate to accurately check the rate of application of the asphalt at any time. Note - Full width processing is required to eliminate longitudinal joints in the stabilizing material necessitating the use of two

(2) or more stabilizing machines; depending on the width of road to be processed. The system for distributing the asphalt material shall be adjustable for the rate of asphalt application and shall measure accurately the amount of asphalt material being applied. A foot per minute meter and a gallon per minute meter shall be in clear view of the operator and both shall be controlled by the operator from the operator’s station.

CONSTRUCTION METHODS

1. Mixing with Asphalt Materials - Prior to adding the asphaltic material, the moisture content of the crushed material shall be adjusted by aerating or by adding water. The asphaltic material shall be added only to that material which can be completely mixed and compacted in one day. The asphaltic material shall be added through the mixer at the rate and within the temperature range directed by the Engineer. The temperature shall be kept below the flash point of the asphalt cement but shall not fall below 350° F. The mixed material shall be laid directly from the multi-drum mixer to the surface. Conveying the mixed material by belt system from drum to surface will not be allowed.

2. Shaping, Rolling and Compacting - Shaping and compacting shall be done while the asphalt material is in a workable state. The final shaping and compaction shall be accomplished as soon as possible after addition of the asphaltic material. The mixed material shall be so shaped that when compacted it shall be in a reasonably close conformity with lines, grades, and cross-sections shown on the plans or as directed by the Engineer. Stabilized material trimmed from the grade shall be used adjacent to the shoulder to complete the cross section as shown on the plans. Material in excess of the quantity required to complete the cross section shall become the property of the Contractor.

Initial rolling shall be done with one or more pneumatic-tired rollers. The aggregate-asphalt mixture shall be compacted to not less than 98 percent of the unit weight obtained by the Michigan Modified T 180 Test as described in the Density Control Handbook. Such test shall be made on the aggregate-asphalt mixture at the filled moisture content existing during the compacting operation.

Required density shall be maintained until the material has been surfaced.

Density testing requirements are hereby waived for this project, but may be used, as directed by the Engineer, to assure density is being maintained. After final rolling, the Engineer will test the surface using a 10-foot straightedge at selected locations. The variation of the surface from the testing edge of the straightedge between any two contacts with the surface shall at no point exceed ±⅜ inch.

3. Curing - The base may be opened to traffic for a period of time to be determined by the Engineer prior to placing of the surface. Any areas which show evidence of cracking or instability will be investigated and corrected within 48 hours, before any work proceeds. If the stabilized asphalt aggregate pavement is to be left unsurfaced for more than seven (7) days, a fog coat of SS-1H shall be applied at the rate of 0.20 to 0.30 gallons per square yard, at the Contractor’s expense.

4. Weather Limitations - Asphaltic material shall not be applied to the grade or to the aggregate when rain is threatening or when the air temperature is lower than 50° F.

The Stabilization work shall be performed in the accordance with weather limitations in Section 501.03.I, unless otherwise authorized by the Engineer.

SPECIAL PROVISION FOR

SANITARY SEWER TESTING

City of Owosso/CW Page 1 of 3 April, 2021

In general, all sanitary sewers and all building connections shall be tested by applying an air pressure test described in the following paragraphs. The Contractor shall be responsible for furnishing all equipment and labor for the air testing. The Municipal Engineer may, as an alternative to or in addition to air testing, require an infiltration test of the sanitary sewers in certain instances.

1. Air Testing: The following described air test is required to be performed on all sanitary sewers.

A. General: The following described test procedure shall be used to determine the adequacy of the pipe joint to hold water and to check for structural defects (such as bell cracks, broken pipe) after completion of backfilling operations. Final air testing shall not be performed until all storm sewer and water main utilities are constructed.

B. Equipment Required: Portable air compressor, standard air hose and connections, minimum of 50 feet of single and triple air hose, 1 single and 1 triple connection pneumatic sewer plug, 1 hand air pump, stopwatch, and 1 air gauge, range 0-30 psi graduated in 1/10's from 0 to 10 psi. All test gages shall be mounted above ground in a suitable test stand.

C. Preliminary Requirements: After all sewer, lateral, and manhole construction and backfilling operations have been completed, the sewer shall be cleaned by the Contractor as follows:

(1) Cleaning: The new sewer shall be cleaned prior to air testing. The Contractor shall clean the sewer by jet rodding and vactoring the debris.

(2) Preliminary Test: Before actual line testing starts, the pneumatic plugs shall pass the following qualifying test in the presence of the engineer and Contractor. One (1) length of sewer pipe shall be laid on the ground and sealed at both ends with the pneumatic plugs to be checked;

air shall be introduced into the pipe until the pipe pressure reaches 15 psi. The pneumatic plugs being checked shall hold against this pressure without bracing being needed, and without movement of the plugs out of the pipe. All pneumatic plugs shall pass the aforementioned qualifications before being used to the actual installation.

(3) Sealing: All tees and lateral stubs shall be suitably capped, sealed and blocked to withstand the internal test pressures. The Municipal Engineer shall determine if additional test pressure is required over the standard 3 psi due to the presence of groundwater.

D. Test Procedures: Immediately following the pipe cleaning described, low pressure air shall be introduced into the sealed line until the internal air pressure reaches 4.0 psi greater than the average back pressure of any groundwater pressure that may be over the pipe. At least two (2) minutes shall be allowed for the air pressure to stabilize. Adequate prior notification shall be given the engineer before running the air test procedure.

(1) Acceptance: The portion of the line being tested shall be accepted if the portion under the test meets or exceeds the requirements of UNI-BELL Specifications. This requirement shall be accomplished by performing the test as follows: The time required in minutes for the pressure to decrease from 3.5 to 2.5 psi (greater than the average back pressure of any groundwater than may be over the pipe) shall not be less than the time shown for the given diameters in the table following this paragraph. If the system does not meet the foregoing requirements, the Contractor will be required to locate and repair the leaks and repeat the tests until the allowable leakage is obtained.

* denotes minimum test time for low air pressure requirements

E. Test Acceptance: The method of testing and measurement shall be approved by the Municipal Engineer.

2. Manhole Test: Vacuum manhole tests shall be used as the preferred test method as approved by the municipal engineer. This type test typically takes about an hour to perform by pulling a vacuum to 10-inches of mercury and holding to no less than 9-inches of mercury.

An exfiltration test may be performed as an alternate method, if conditions warrant such method.

All pipes for this method shall be plugged and the manhole filled with water to the bottom of the casting. After a stabilization period, the fall of water will be measured to determine the exfiltration rate. The maximum allowable exfiltration shall not exceed 0.5 gallons per foot of depth per foot of diameter per 24 hour day. All materials, labor, and water shall be furnished by the Contractor.

One or both test methods, as determined by the municipal engineer, shall be performed by the contractor at each manhole if conditions dictate.

3. PVC/GRP Deflection Tests: The completed installation of PVC or GRP sewers shall at no point have out-of-round pipe deflections greater than 5.0%. Deflectometer or go no-go gauging tests shall be performed prior to acceptance on all PVC and GRP sewers. The test shall be conducted after the final backfill has been in place at least 30 days.

4. Post Construction Infiltration: Following complete construction and prior to connection of services to the sewer, the engineer shall have the option of requiring retesting of any section of sewer where excessive infiltration is observed or suspected.
