Increased Rap Usage to 30

• VDOT adopted a state wide specification allowing
  rap up to 30.
• This has allowed for a reduction of PG binders
  necessary in a mix.
• Allowed for a change in binder properties
  reducing the need for PG 70-22.
• Allowed for reduced material storage at the
  plants.
• The change allowed for savings to be passed on to
  VDOT in bids received in 2008.

5
Rideability Specifications

• A standing subcommittee continues to work on this
  specification
• Strived to make sure that the specifications are
  uniformly adapted.
• Application of Rideability Specification
  Guidelines issued by Materials August 22, 2008.
• Support a uniform specification between
  Maintenance and Construction

6
On Call Equipment or Paving

• In an effort to reduce the cost of pavement
  patching
• Discussions with the districts have taken place
  regarding the cost effectiveness of this type of
  equipment rental work.
• A draft directive is being developed to reinforce
  the guidelines to be followed within each
  District.
• Separate contracts are being developed in
  response to patching needs.

7
Milling

• Specifications allow for performance milling to
  effectively move the work ahead in an orderly
  fashion. However the quantity measurement for
  pay is ½/sy for maintenance contracts compared
  to 1/sy for construction contracts.
• JAPMC supports a consistent specification one
  that is uniform between maintenance and
  construction contracts.

8
Lane Restrictions

• Within Districts several different restrictions
  may affect the hours of operations.
• Hour restrictions reduce production, extend the
  time frame of the contacts, and increase the
  cost.
• System Operations Regions map was provided to the
  industry to better understand those regions.
• On going discussions will continue regarding time
  restrictions.

9
Continuing Items

• Striping issues - meeting project requirements
  due to traffic and specification requirements.
• Need for temporary pavement marking item.
• Portable signs and conversion to posted mounted
  signs.
• Review the requirements to make sure there is a
  cost benefit.
• CQIP reviews the affect that it has on projects.

10
Continuing Items

• In an effort to better understand the reasons
  behind specifications or procedures and their
  impacts on pavements
• Experts will be brought in to discuss issues
  related to specifications, traffic, and
  materials.
• It is imperative that cost benefit justifications
  be evaluated for all changes.
