615.01Description.This work consists of providing, maintaining, and subsequently removing roads and pavements for maintaining traffic.

615.02Fences.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 Contractormay 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 Engineerwill notify the property owner to reinstall permanent fencing according to the Right-of-Way settlement.

615.03Earthwork.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.

615.04Guardrail.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 Contractorto re-use material in good condition.

615.05Pavement.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.

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 Engineerwill 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 Contractormay use Type 2 surface.

[2]Meet intermediate course requirements.

[3]The Contractormay use 301 or 448 Type 2 intermediate course.

 

For the indicated pavement type and courses, conform to the requirements for the pertinent items except as modified below.

For rigid pavements, conform to Item 452.Tiebars or hookbolts 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.Do not follow the joint sealing requirements of 451.15.Use Class F concrete.However, 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 Contractorspreads and finishes the materials by acceptable hand methods, the Department will waive the requirements for smoothness.Use a PG 64-22 asphalt binder, unless part of the temporary pavement is to be incorporated into the permanent pavement.

For a 304 course, if the Contractorspreads 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.

615.06Sidewalk.If temporary walks are required, provide one of the types specified in Item 608.

615.07Maintenance.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 Engineerdetermines that the Contractoris not properly maintaining the temporary facilities, the Department may put them into proper condition according to 105.14.

615.08Removal.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.

615.09Method of Measurement.The Department will measure the quantity of Pavementfor Maintaining Trafficby the number of square yards (square meters) of pavement surface placed, maintained, and removed as directed, measured complete in place.

The Department will measure the quantity of TrafficCompacted Surface under Item 410 and Calcium Chloride under Item 616.

615.10Basis of Payment.Payment for Roads for Maintaining Trafficwill not include those specified for Item 410 Traffic Compacted Surface or Item 616 Calcium Chloride.

If the Department puts temporary facilities into the proper condition due to the Contractorís failure to do so, the Department may deduct the cost required to perform this service from money due or may become due the Contractor.

The Department will pay for accepted quantities at the contract prices as follows:
