Effective PreventiveMaintenance

1-11


12/56

Type of PavementMaintenance Preventive (Proactive)

Arrest light deterioration

Retard progressive failures

Reduce need for corrective maintenance

“Right” treatment at the “right” time!

Corrective (Reactive)

After deficiency occurs

More expensive

1-12


13/56

When Do We Have to Fix Our Pavements? Pavement Preservation

preserves good condition pavement

Corrective maintenance When the pavement loses load carrying ability

(excessive deflection)

Waterproofing (cracks)

Surface slope (rutting) Surface roughness (too slick)

Ride quality (bumps)

Asset Management . . . is a systematic process of

maintaining, upgrading, and operatingphysical assets cost-effectively

. . . Combines the use of soundengineering principles, accepted businesspractices, and economic theory to improve

the decision-making process

PROGRAMMING PROJECTS

How to program pavement projects with emphasis on PavementPreservation and Long Life Pavement

1-37


38/56

A Step by Step Process Responsible parties to submit project

nominations Hold coordination meetings to develop

proposals Draft list of projects developed and submit for

review Hold public meetings on projects under their

jurisdiction to be included in the STIP Draft constrained list of projects published for

public comment

1-38


39/56

Project Scoring 50%

Related to some form of direct transportationpreservation or enhancement criteria

25%

Projects which improve the safety of thetransportation system

25% Economy along with customer input

Evaluates each,

individual project interms of how much itcontributes to finishingthe overall plan foreach planning corridor.

Road Classifications Importance in

providing connectivityand the functions they

provide. The basic principal is

that roads serve twodistinct functions:

Mobility (the movementof goods and people)and

Access to land

1-45


46/56

Mobility Build, operate and

maintain atransportation system

that will Reduce traffic

congestion and

Improve travel

reliability (Volume toCapacity ratio)

1-46


47/56

Mobility Level of Service (LOS)

Improvement

LOS serves as a

measure of a road’sperformance/congestionlevel that utilizes agrading scale

A LOS of “A” representsno congestion and LOS“F” represents severe

congestion

Inter-government Agreements Cooperative

agreements havebeen reached in

which both statesagree to complete thefacility

Percent Complete The amount of design

and engineering workcompleted on a

project is representedas a percent of thetotal preliminaryengineering and

design work required

Safety Crash density is the number

of crashes per mile occurringalong a section of highway

Relative severity indexrepresents the relative cost tosociety by estimating theannual cost of crashes for a

section of road

1-50


51/56

Safety Fatality rate of the

section divided by the2003 fatality rate of

1.12 fatalities per 100Million Vehicle Milesof Travel

Economic Development To measure a project’s influence on future

economic development,

Job Creation,

Job Retention,

Level of Investment,

Cost Effectiveness and

Economic Distress of the surrounding county.

Local Inputs The value of local input from a variety of

stakeholders is significant enough to warrantadditional points for projects

Input will be broken down into three distinctsources: Local Planning Agency input up to 4 points

(MPO’s & RPO’s)

Mayors & County Commissioners up to 3 points(local elected officials)

Citizen and Legislative input up to 3 points
