253.02 Removal of Existing Pavement
253.03 Placement of Asphalt Concrete
253.01
Description. This work consists of removing existing
asphalt concrete, brick, portland cement concrete, or aggregate pavement
courses; shaping and compacting the exposed material; and placing new asphalt
concrete pavement or aggregate and asphalt concrete pavement courses.
The plans
show details about the repairs and replacement material.
253.02
Removal of Existing
Pavement. The Engineer will designate
the location and limits of areas to be repaired. Provide the Engineer with aerosol spray paint
to outline those areas for repairs.
Repair the full depth of the pavement, unless otherwise shown on the
plans.
Cut the
existing pavement at the limits specified and as necessary to prevent
disturbing or undermining the remaining pavement during removal. Completely remove pavement in the repair area
to the specified depth without displacing, undermining, or otherwise damaging
the remaining pavement. Dispose of
removed pavement according to 202.
253.03
Placement of Asphalt Concrete. Shape and compact the exposed underlying
material as the Engineer directs.
Before placing asphalt concrete, clean all vertical faces of the
existing pavement and coat them with asphalt material according to 401.14.
Place the replacement material in lifts as the Engineer directs. Thoroughly and uniformly compact each lift
using suitable compaction equipment as the Engineer directs. Finish the final lift flush with the existing
pavement surface.
Thoroughly
compact the final lift using a pneumatic tire roller that conforms to 401.13.
As the rolling progresses, add additional patching material, as
necessary, to produce a smooth surface flush with the existing pavement
surface.
Continuously
compact each lift while the material is in a workable condition throughout the
depth of the lift.
Trim the
limits of the repair to form a vertical
face
1.5 inches (38 mm) deep from the surface before placing
the final asphalt concrete layer adjacent to the existing pavement unless the
repair is covered with an overlay within 60 days.
If the
Contract does not include resurfacing, seal the perimeter surface of the
repaired areas by applying a nominal 4 inch (100
mm) wide strip of approved 702.04 asphalt
material, RS-1, RS-2, CRS-1, or CRS-2 or 702.01
approved PG binder.
After
completing repairs, restore the existing shoulders to the condition that
existed prior to the repair work.
253.04 Method
of Measurement. The Engineer will
measure the quantity of Pavement Repair
by either the number of square yards (square meters) or cubic yards (cubic
meters) of pavement repaired in the complete and accepted work, calculated
using the dimensions established by the Engineer. The Engineer will not measure removal and
replacement pavement beyond the designated limits.
253.05 Basis
of Payment. Payment is full compensation for furnishing all materials, including aerosol
spray paint and replacement and restoration materials; cutting,
removing, and disposing of existing pavement; shaping and compacting the
exposed underlying material; placing new pavement; and restoring the shoulders
and for all labor, equipment, and incidentals necessary to complete this work.
The
Department will pay for accepted quantities at the contract prices as follows:
