9. • Includes urban and rural principal arterials, and
main thoroughfares that carry heavy volumes of
traffic,
• Most on the state highway system and some are on
local roads.
• Many of these local roads function as main streets
for communities and serve commercial areas and
central business districts.

10. • New designated NHS roadways must use AASHTO
Green Book standards to meet design expectations
required as part of the NHS classification.
• Design exceptions are remain an available
mechanism in certain situations.

11. • Federal law gives the state DOT authority for
selecting projects on the NHS in consultation with
local officials. This potentially gives the state DOT
a larger role in selecting projects on local roads,
though this will likely not require a burdensome
process.

12. SEC. 1103. DEFINITIONS.
(a) Definitions- Section 101(a) of title 23, United States Code, is amended—
‘‘(2) ASSET MANAGEMENT.—The term ‘asset management’
means a strategic and systematic process of operating,
maintaining, and improving physical assets, with a focus
on both engineering and economic analysis based upon
quality information, to identify a structured sequence of
maintenance, preservation, repair, rehabilitation, and
replacement actions that will achieve and sustain a desired
state of good repair over the lifecycle of the assets at
minimum practicable cost.’’;

13. SEC. 1507. MAINTENANCE
Section 116 of title 23, United States Code, is amended—
(a) Definitions- In this section, the following definitions apply:
‘‘(2) PAVEMENT PRESERVATION PROGRAMS AND
ACTIVITIES.— The term ‘pavement preservation
programs and activities’ means programs and activities
employing a network level, long-term strategy that
enhances pavement performance by using an integrated,
cost-effective set of practices that extend pavement life,
improve safety, and meet road user expectations.’’;

14. Sec. 134. Metropolitan Transportation Planning
Title 23, United States Code, is amended—
(h) Scope of Planning Process. -
(1) In general. - The metropolitan planning process for a
metropolitan planning area under this section shall
provide for consideration of projects and strategies that
will –
(H) emphasize the preservation of the existing
transportation system.

15. Sec. 134. Metropolitan Transportation Planning
Title 23, United States Code, is amended—
(i) Development of Transportation Plan. -
(2) Transportation plan. - A transportation plan under
this section shall be in a form that the Secretary
determines to be appropriate and shall contain, at a
minimum, the following:
(G) Capital investment and other strategies. -
Capital investment and other strategies to
preserve the existing and projected future
metropolitan transportation infrastructure
and provide for multimodal capacity increases
based on regional priorities and needs.

17. Traditional Alternative
D.I. – is distress index, a measure of pavement condition. Scale values: 100=no
distress, 50=when reconstruction is required.
R.S.L. – is remaining service life, the time remaining that a pavement can be
preserved.
