Section 26 – Cold Plane Asphalt Concrete Pavement

26-4 PLANED PAVEMENT CONFORMS

Planed pavement conforms shall be constructed at the limits of the Work as shown or

specified in the Contract and as directed by the Agency.

Except on residential streets or where otherwise shown or specified in the Contract, where

the beginning or ending limit is a cross street, a fifty-foot (50’) planed conform extending to the

round corner of the cross street shall be constructed to the dimensions and depths of cut shown

or specified in the Contract. On residential streets, an eighteen-foot (18’) planed pavement

conform shall be constructed. The slope of the temporary asphalt concrete tapers at the limits

shall not be greater than one inch (1”) vertical to thirty-six inches (36”) horizontal.

Where the beginning or ending limit is not at a cross street, or where a cross street or other

such feature that is not to be resurfaced causes a discontinuity in the Work, a planed pavement

conform shall be constructed. The conform shall span the full width of the street for a distance

of fifty feet (50’) back from the limit line or feature causing the discontinuity in the work. At

bridge decks the conform shall span the full width of the street for a distance of fifty feet (50’).

The depth of cut shall be one and one-half inches (1-1/2”) at the limit of work and shall be

progressively decreased to zero (0”) over the conform length.

Planed pavement conforms shall also be constructed at freeway entrance and exit ramps

and at right and left long-radius turn lanes which diverge from or converge onto the street to be

resurfaced. These conforms shall span the full width of the ramp or turn lane for a distance of

eighteen feet (18’) and shall be constructed where shown on the Plans or directed by the

26-5 PAVEMENT REINFORCING FABRIC

Pavement reinforcing fabric shall be installed in conformance with the provisions in Sections

39-4.03 and 88-1.02 of the State Standard Specifications, the manufacturer's recommendations,

Pavement fabric shall be used in pavement overlay areas where shown or specified in the

Contract and shall extend at least two feet (2') beyond any joints between the new pavement

section and the overlay section. When installed, the fabric shall be a minimum of twenty-four

inches (24”) away from the lip of gutter and from the edge of pavement.

After thoroughly cleaning the surface to receive fabric, all cracks greater than one-quarter

inch (1/4”) in width shall be filled with a hot asphaltic crack filler and allowed to cure. Crack filler

shall not extend above the existing pavement surface. Crack filler material shall be paid for

under the unit price bid per pound for crack filler, and no additional payment will be made. If a

leveling course is used, crack sealing is not required. Type “A” three-eighths inch (3/8”)

maximum gradation leveling course material shall be placed prior to pavement reinforcing fabric.

Leveling course material shall be placed as shown on the Plans and paid for under the unit

price bid per ton for asphalt concrete, and no additional payment will be made.

Pavement fabric binder shall be AR4000. The minimum asphalt binder temperature shall be

290 degrees F, with a distributor tank temperature not to exceed 324 degrees F. The asphalt

binder shall be placed at a rate of one-quarter gallon (0.25 gal.) per square yard, or as directed

If mechanical laydown equipment is used, it must be capable of handling full rolls of fabric

and be capable of laying the fabric smoothly without excessive wrinkles and/or folds.

Cold planing asphalt concrete for pavement keycutting will be measured by the linear foot

for the pavement keycutting width shown or specified in the Contract. The quantity to be paid

for will be the actual length of pavement cold planed, irrespective of the number of passes

required to obtain the specified depth.
