615.01 Description. This work consists of providing,
maintaining, and subsequently removing roads and appurtenances, and pavements
for maintaining traffic.
615.02 Fences. If necessary,
replace permanent fencing with temporary fencing while occupying any temporary
Right-of-Way, provide, erect, and maintain comparable temporary fencing during
the period of construction. Take ownership of the existing fence.
The Contractor may use this material in the erection of the temporary fence.
Before occupancy of the temporary
Right-of-Way is terminated and before removal of the temporary fence, the
Engineer will notify the property owner to reinstall permanent fencing
according to the Right-of-Way settlement.
615.03 Earthwork. Excavate and construct
embankment necessary for providing and maintaining temporary roads and any
associated drainage facilities, as well as subsequent removal of temporary
roads and restoration of the areas to their original condition, according to
Item 203. Construct adequate side ditches in
cut sections, and provide drainage pipe and culverts where necessary.
Ensure that the width of the road from out to out of the shoulders is not less
than 26 feet (7.8 m) and the side slopes are not steeper than 1.5:1, unless
otherwise shown on the plans. If sidewalks are required, increase the
width of embankment accordingly.
615.04 Guardrail. Where the height
of the embankment is 5 feet (1.5 m) or more, measured at the outside edge of
the berm, and the side slope is steeper than 4:1, provide guardrail at a
distance of at least 1.5 feet (0.5 m) from the edge of the required width of
the surface course. Conform to one of the types of guardrail specified in
Item 606, except that the Department will allow the
Contractor to re-use material in good condition.
615.05 Pavement. Unless otherwise shown on the
plans, ensure that the pavement surface is not less than 20-feet (6.0 m) wide
and is constructed of the materials and in the manner specified.
Prepare
the subgrade in accordance with 204.03
and 204.04
Provide
subgrade conforming to Item 204.03.
Soft subgrade will be determined and replaced according to Item 204.04.
If
a traffic-compacted surface course is shown on the plans, construct it
according to Item 410. Furnish and apply
calcium chloride according to Item 616. The
Engineer will specify the amount of original and subsequent applications of
aggregate and calcium chloride.
Where
Class A or Class B pavement is shown on the plans, provide either rigid
pavement or flexible pavement conforming to the following minimum requirements:

[1]
Meet surface course requirements. The Contractor may use Type 2
surface.
[2]
Meet intermediate course requirements.
[3]
The Contractor may use 301 or 448 Type 2 intermediate course.
For the
indicated pavement type and courses, conform to the requirements of the
specified items except as modified below.
For rigid
pavements, conform to Item 452. Tiebars or hook bolts for longitudinal joints are not
required. Use dowels only at transverse expansion and construction
joints. Conform to the quality requirements set forth in 499.02 for the materials, except the
requirements of 703.13. Use Class
QC-1 concrete. For any part of the 452 pavement
that is to be incorporated into the permanent pavement, the above exclusions do
not apply and conformance to Items 452 and 499 is required.
For
a 448 course, if the Contractor spreads and
finishes the materials by acceptable hand methods, the Department will waive
the requirements for smoothness.
Use
a PG 64-22 asphalt binder for temporary asphalt pavement. If any part of the
temporary pavement will be incorporated into the project permanently, then use
the contract-specified PG asphalt binder grade for the pavement course.
For a 304 course, if the Contractor spreads the aggregate
by approved hand methods, the Department will not require side forms. If
the 304 course is to be removed, the Contractor
may use reclaimed asphalt concrete or Portland cement concrete pavement.
Determine
the thickness of the courses by field measurement.
615.06 Sidewalk. If temporary walks are required,
provide one of the types specified in Item 608.
615.07 Maintenance. Maintain all portions of the
temporary facilities in good condition with respect to both safety and
smoothness for travel as long as it is needed for maintenance of traffic.
If the Engineer determines that the Contractor is not properly maintaining the
temporary facilities, the Department may put them into proper condition
according to 105.15.
615.08 Removal. If the temporary facilities are
no longer needed, remove them, except such portions of the embankment as are
shown on the plans to be a part of the new roadway embankment, and leave the
area in a neat condition.
Take
ownership of all material removed, unless otherwise shown on the plans.
Use all suitable material in the work or legally use, recycle, or dispose in
accordance with 105.16 and 105.17.
615.09 Method of Measurement. The
Department will measure the quantity of Pavement by the number of square yards
(square meters) of pavement surface placed, maintained, and removed as
directed, measured complete in place.
The
Department will measure areas of soft subgrade, undercut and replaced,
according to 204.08.
The
Department will measure the quantity of Traffic Compacted Surface under Item 410 and Calcium Chloride under Item 616.
615.10 Basis of Payment. Payment for Roads for
Maintaining Traffic will not include those specified for Item 410 Traffic Compacted Surface or Item 616 Calcium Chloride.
Payment
for Roads for Maintaining Traffic includes the installation, maintenance, and
removal of all fencing, earthwork, guardrail, sidewalk, and all other items as
necessary to provide a complete, functional, and safe installation for public
use.
The
Department will pay for areas requiring undercut and replacement conforming to 204.04 according to 204.09.
The
Department will pay for accepted quantities at the contract prices as follows:
