617.01  Description.  This work consists of preparing the shoulder, and furnishing and compacting additional aggregate on the existing or prepared shoulder.

Use removed or excavated materials in the Work when the material conforms to the specifications; if not, then recycle or dispose of the material according to 105.16 and 105.17.

617.02  Materials.  Furnish materials conforming to 703.18.

617.03  Prosecution.  If reconditioning shoulders as part of a resurfacing project and traffic is maintained, place shoulder material along with the paving operations as rapidly as possible.  Complete all shoulder reconditioning within four days following the placement of the surface course or any course that results in a drop-off of 2.0 inches (50 mm) or greater.

617.04  Shoulder Preparation.  If shoulder preparation is specified, loosen the existing surface to a depth of 1 to 2 inches (25 to 50 mm).  If the surface is an asphalt mix or seal, cut the surface along the edge of the pavement with a blade or disc to give a straight vertical edge.  Reduce pieces of loosened material that exceed approximately 1 1/2 inches (38 mm) in size to at least this maximum size or consider these pieces unsuitable material.  Remove and dispose of oversized or other unsuitable material that would interfere with placing of aggregate.  Reshape the loosened material as necessary to conform to the requirements for placing aggregate.

617.05  Furnishing and Compacting Additional Aggregate.  Spread aggregate with approved spreaders.  Do not dump or store aggregate on the pavement.  Remove spilled aggregate from the pavement as spreading progresses.

Where the shoulder is relatively level, compact the material using crawler-type tractors, tamping rollers, trench rollers, suitable pneumatic tire rollers, or other suitable equipment. Use a minimum of four passes with compaction equipment weighing at least 6 tons (5 metric tons). Perform the final compaction of the surface of the shoulder using a pneumatic tire roller. Where it would be unsafe to use the above compaction equipment due to the grade or width of the shoulder, use a side-mounted roller or side-mounted vibrating plate compactor that is securely attached to a tractor or other construction equipment. The side-mounted roller or side-mounted vibrating plate compactor must be able to adequately compact the aggregate while the equipment to which it is mounted remains on the paved surface. Use a minimum of four passes with the side-mounted roller and two passes with the side-mounted vibrating plate compactor. Compact the aggregate immediately after the spreading operation to prevent the loss of contained moisture and displacement of the material.

Apply water as directed by the Engineer when required to aid compaction and to prevent segregation of the material.

617.06  Method of Measurement.  The Department will measure Shoulder Preparation by the number of square yards (square meters).

The Department will measure Compacted Aggregate, by the number of cubic yards (cubic meters) in place computed from the profile grade and typical sections.

The Department will measure Water by the number of M gallons or 1000 gallon units (cubic meters) according to 616.03.

If the plans provide for the use of aggregate in a variable width or depth course and the Department cannot readily calculate the quantity from profile grade and typical sections, the Department will measure the cubic yards (cubic meters) by converting from weight using the following conversion factors:

Table 617.06-1


Conversion Factor

Crushed stone

3800 lb/yd3

2250 kg/m3

Crushed gravel

3900 lb/yd3

2310 kg/m3

Crushed slag [1]



   less than 90 lb/ft3 (1450 kg/m3)

3600 lb/yd3

2140 kg/m3

   90 to 100 lb/ft3 (1450 to 1600 kg/m3)

4000 lb/yd3

2375 kg/m3

   more than 100 lb/ft3 (1600 kg/m3)

4500 lb/yd3

2670 kg/m3

Recycled Portland Cement Concrete

3400 lb/yd3

2020 kg/m3

Recycled Asphalt Concrete Pavement

4000 lb/yd3

2375 kg/m3

[1]  Based on average dry rodded weight of standard sizes of slag aggregates on record at the Laboratory.  The conversion factors listed are the long gradation weights.  These numbers are based on the dry rodded weights of No. 67, 57, or 8 gradation.  The Department will determine slag weights based on weights obtained from the original source.


The Department will classify salvaged or mixed materials according to the material that makes up the majority of the mixture.

The moistures of the delivered material will be less than 2 percent above saturated surface dry condition or the payment will be based on the dry densities and dry weights.

Furnish freight bills or certified weigh bills according to Item 109.
