In 1993 the Metropolitan
Government Pavement Engineers Council (MGPEC) was established to represent all of the cities and counties in the DRCOG (Denver
Regional Council of Governments) planning area. Specific Goals Statements
were set forth as follows:
Improve the quality of pavements throughout the Denver-Metropolitan
Region, and lower the life-cycle cost of pavement maintenance at the local level through the use of standardized paving materials
and uniform design, construction, and maintenance practices. This goal is being achieved through the complete
Uniform Specification for Asphalt Mix Lab Design, and by the development and publication for a regional pavement design and
construction manual for local governments in the Denver Metropolitan Region. (See item below entitled Completed
Projects and Current Projects).
Improve information sharing and provide educational
opportunities for the MGPEC membership concerning the planning, design, materials, specification, construction practices,
maintenance practices, pavement management, inspection, and testing of pavements. Improve communication
between jurisdictions, MGPEC, Denver Regional Council of Governments (DRCOG), Colorado Department of Transportation (CDOT),
Federal Highway Administration (FHWA), universities, private industry, and industry associations such as the Asphalt Institute,
Colorado Asphalt Pavement Association (CAPA), and the American Concrete Pavement Association (ACPA).
Ensure pavement design specifications and standards
developed at the state and federal levels are feasible and applicable for usage at the local level in the Denver area.
As MGPEC has evolved, additional Specific
Performance Objectives have been set forth:
Improve the awareness of local, state and federal engineers
and officials concerning the extent of paving work accomplished in the Denver-Metropolitan Region, and the financial implications
of this work for the citizens we serve.
Promote pavement management programs for all local
governments in the Denver-Metropolitan Region, and to provide experienced technical assistance to the members in the implementation
of individual pavement management programs.
3. Obtain funding from state and federal sources to conduct the research which is
necessary to achieve MGPEC’s goals and implement the specified projects.
The Council continues working to resolve paving issues common to all of the agencies.
MGPEC Uniform Specification
for Asphalt Mix Lab Design, Field Control Testing and Pavement Construction
The uniform specifications were
developed with representation from MGPEC and CAPA (Colorado Asphalt Pavement Association) during the winter of 1995-1996.
Prior developmental work started in the summer of 1994, with help from representatives of CDOT (Colorado Department
of Transportation). In March of 1998, the first version of the MGPEC Uniform Asphalt Specification
was issued. This specification was incorporated in the Regional Pavement Design and Construction Manual. In
2001, a revised edition of the MGPEC Pavement Design Standards and Construction Specifications Manual was issued. Since
that time revisions have been made to several items within the Specifications Manual. In 2012, MGPEC issued an
updated and revised Form #9.
The MGPEC Uniform Specifications were developed with the following Goals in mind:
Reduce the number of specified mix designs in the metro
Incorporate existing specifications where feasible.
Cover 70% to 80% of the local Agency functional classification
needs: Residential, Arterial, some Collector.
· Initial specification should use ‘State of the Practice’ as a baseline, and improve from
Use as much common practice as possible while acknowledging
that the industry and CDOT (through SHRP and the SuperPave mix design system) are moving towards a more performance related
specification from the current ‘recipe’ or method type specification.
· The specification should ‘Stand Alone’ without excessive references and make clear which
project specific mix design criteria is needed.
· Use a standard format based upon FHWA / AASHTO guidelines similar to the CDOT “Standard Specifications for Road
and Bridge Construction” 1991 edition (‘Brown Book’), while keeping clear that this specification is ‘different’.
