• 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.

• 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.

• 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.

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.’’;

SEC. 1507. MAINTENANCESection 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.’’;

Sec. 134. Metropolitan Transportation PlanningTitle 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.

Sec. 134. Metropolitan Transportation PlanningTitle 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 infrastructureand provide for multimodal capacity increases based on regional priorities and needs.

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.
