Program Goal Pavement Management System

AASHTO Guide for Design

of Pavement Structures

(1993)

Pavement Deterioration Curve Starting Point

Priority on pavements in the worst

condition

Less pavement is rehabilitated with

available funding

Better pavements get worse

Seem to always need to “catch up” on

repairs

Worst First

Repair with PMS: Maintain pavements in

better condition and Repair at Right Time at

and Cost.

Costs of repairs are less: More pavement

repaired.

The disadvantage: Higher operational costs

More cost effective to repair pavements

with PMS plan

than allowing the better pavements to

become poor

Best First – PREFERRED FOR PITTSFIELD

Pavement Management Program 1

Step 1: Inventory and inspection Assess your Pavement System/Network

Step 2: Work plan development Financial & Action Planning

Step 3: Engineering document preparation

Step 4: Construction contract administration

Step 5: On-site construction management

Condition 5 – Fair

Visible Distresses Treatment Measures /

General Conditions

Longitudinal and

transverse cracks

(open ½”) show first

signs of slight

raveling and

secondary cracks.

Some patching or

Needs chipseal or

other thin treatment.

Condition 2 – Very Poor

Determine what factors are

important for repair project selection

Condition, material, priority,

use,….etc.

Determine how the above factors

should be weighted for the NPR
