<br />the Standard Specifications, the surface of the grading plane
<br />shall not be more than 0.05 foot above or below the grade
<br />established by the Engineer.
<br />Before grade is approved by the Engineer all earthwork
<br />(including driveways and slopes) shall be compacted to grade.
<br />Unless otherwise shown on the plans, all surplus materials not to
<br />be salvaged, stockpiled or disposed of as provided in Section
<br />19-2.06 shall become the property of the Contractor and disposed
<br />of as provided in Section 7-1.13 of the Standard Specifications.
<br />Unless otherwise shown on the plans, the existing pavement,
<br />when used as embankment, shall be broken up into pieces not larger
<br />than 0.33 foot in greatest dimension.
<br />19-2 EARTHWORK (STRUCTURE EXCAt►ATION i BACKFILL). --Structure
<br />excavation and backfill shall conform to the requirements in Section
<br />19-3, "Structure Excavation and backfill'# of the Standard
<br />Specifications and these special provisidns.
<br />All references to culvert excavation and culvert backfill on the
<br />plans shall be deemed to mean structure excavation and structure
<br />backfill, respectively, in the Standard Specifications and these
<br />special provisions,
<br />Structure Backfill which is outside of the paved portions of the
<br />roadway, unless otherwise specified on the plans, shall be native
<br />material selected for its resistance to erosion.
<br />Compaction Requirements: Unless otherwise shown on the plans,
<br />the compaction requirements within the limits of structure excavation
<br />for pipes and arches shall be as shbwn on Improvement Standard A-7.
<br />PONDING AND JETTING will be perinitted only if a maintenance bond
<br />in the amount of twenty percent (20x) of the contract price with a
<br />corporate surety approved by the County is provided. Such a bond
<br />shall be provided before final acceptance of the project by the
<br />County and shall guarantee the repair of all damage due to faulty
<br />materials or workmanship provided or done by the contractor. The
<br />guarantee shall remain in effect fol' a period of three (3) years
<br />after the date of final acceptance of the project by the County.

<br />Specifications and these special provisions.
<br />Aggregate Base shall be Class 2.
<br />The combined aggregate shall conform to the grading specified
<br />for the 3/4 -inch maximum aggregate.
<br />The R -Value requirement may be waived provided the individual
<br />test result of the aggregate base conforms to the specified grading
<br />and durability and has a sand equivalent value of 33 or more.

<br />39-1 ASPHALT CONCRETE. --Asphalt Concrete shall conform to
<br />the requirements in Section 39# ('Asphalt Concrete", of the
<br />standard Specifications and these special provisions.
<br />Asphalt concrAtn shall be Type "B". Aggregate, shall conform
<br />to the 1/2 -inch maximum, coarse or medium grading as determined
<br />by the Engineer. At the contractbrs option# and with approval
<br />of the Engineer# aggregate may be 3/4 -inch maximum, medium grading
<br />with the exception of the final finish course.
<br />Aggregate conforming to the 11/8 -inch maximum grading will be
<br />permitted for use in driveways, dikes and other areas with
<br />approval of the Engineer.
<br />The amount of asphalt binder to be Mixed with the aggregate
<br />shall be between 5 percent and 7 percent by weight of the dry
<br />aggregate. The exact amount of adphalt•binder to be mixed with
<br />the aggregate and the AR viscosity grade of the asphalt binder
<br />will be determined by the Engiheek.
<br />Paint binder shall be applied at a rate of approximately
<br />0.05 gallon per square yard# uhleba otherwise shown on the plans.
<br />When the asphalt concrete is to be produced in a batch plant,
<br />the asphalt concrete shall be propbrtioned and mixed by the
<br />automatic method.
<br />All steel -tired rollers shall be of the tandem type.
<br />When shown in tht Engineer's Estimate prime coat liquid
<br />asphalt penetration grade shall be SC 70 or SC 250 as directed by
<br />the Engineer,
<br />The dumping of material in a Windrow, in accordance with
<br />Section 39-5,01# shall be limited to 150 feet in advance of the
<br />paving machine, uniess otherwise pdrinittbd by the Engineer.
<br />Unless otherwise shown on the planar asphalt paver equiptnent used
<br />to place asphalt concrete shall be equipped with full automatic
<br />screed and grade sehsing Controls Uhich &hall control the longitudinal
<br />grade and trahavtYae slope of the screed: The controls shall be
<br />actuated by grade and slope references. Corrections on account
<br />of deviations from the rtferencts bhall be automatic. Guides and
<br />references required to control the longitudinal grade and transverse
<br />slopes shall be furnished and installed by the contractor.
<br />Should the contractor elect to use a ski device sensing from
<br />subgrade for longitudinal control, the minimum length of the device
<br />shall be 30 feet. The device shall be a rigid unit mounted on multiple
<br />supports. Each support shall act independently of others and the
<br />finished grade shall not be affected by the action of a single support.
<br />In addition:
<br />I. The viscosity grade of paving asphalt shall be AR -4000.
<br />2. In no case shall the minimum asphalt content be below 5.3% of the dry
<br />aggregate weight.
<br />3. All surface courses of -Asphalt Concrete shall have 1/2" maximum
<br />aggregate and a minimum of 5.8% asphalt.
<br />4. Alternate compacting equipment or substitution of a vibratory roller for a
<br />pneumatic -tired roller will not be permitted or approved.
