GOT PASER?

Are YOU informed about the condition of our Indiana roadways?

Do YOU know what PASER is?

PASER is an acronym that stands for Pavement Surface Evaluation and Rating System.

WHY is PASER Important?

PASER is a comprehensive pavement management system that collects data and assesses a variety of road characteristics in a rating system scale. Through visual evaluations we can understand the conditions of the pavement and take action to make sure that we are not creating hazardous conditions for our local motorists. It is a tool that we can all use to make better decisions regarding the maintenance and repair of our local roadways. Over time, a PASER System is an amazing tool that can SHOW YOU the roadway conditions year over year and allow you to make better decisions. See Chart Below.

PASER Historical Chart

PASER involves three major steps to investigate and manage local roads:
1) Inventory Process
2) Phased Evaluation of all Pavement Conditions
3) Create prioritized solutions based on the evaluated conditions and possible alternative roadway treatments

What are the Keys to Asphalt Pavement Distress?

There are four major categories to look for and understand the causing conditions. This is VERY important to select to correct maintenance program or roadway rehabilitation.

Four Categories of Asphalt Pavement Distress Evaluation:

1) Surface Defects – including raveling, flushing and polishing.
2) Surface Deformation – including rutting, distortion, rippling & shoving, settling, frost heave
3) Cracks – including transverse, reflection, slippage, longitudinal, block, and alligator cracks
4) Patches and Potholes – (The kind that makes you replace and blow a tire).

How do you rate pavement surface conditions?

Pavement surface conditions on rated on a scale rating system. The lower the score the worse the road condition. For example, a rating of 1-3 represents (FAILED – POOR), 4-5 (FAIR), 6-8 (Good – Very Good), and 9-10 (Excellent). Every roadway is documented and rated in an external database with images of each roadway segment. Below are examples of roadway images and their ratings.

PASER-Rating-1-Fail Rating (1) Fail – Potholes, Pavement Failure, Rutting, Poor Drainage
PASER-Rating-1-Fail-2 Rating (1) Fail – Rutting, Distortion, Alligator Cracking
PASER-Rating-2-Very Poor Rating (2) Very Poor – Alligator Cracking, Chicken Wire Cracks, Loss of Pavement, Distortion
PASER-Rating-2-Very Poor2 Rating (2) Very Poor – Longitudal Cracking, Centerline Cracking, Rutting, Distortion
PASER-Rating-3-Poor1 Rating (3) Poor – Flushing, Raveling, Loss of Surface Material
PASER-Rating-3-Poor2 Rating (3) Poor – Raveling, Polishing, Exposure of Aggregate
PASER-Rating-4-5-Fair1 Rating (4-5) Fair – Raveling, Flushing, Polishing, Exposure of Aggregate
PASER-Rating-4-5-Fair2 Rating (4-5) Fair – Raveling, Aggregate Particles worn away tops of Large Aggregate
PASER-Rating-6-7-Good1 Rating (6-7) Good – Slight Raveling and Flushing, Slight Distortion
PASER-Rating-6-7-Good2 Rating (6-7) Good – Slight Rutting, Tight Centerline Cracks (Less than 1/4″)
PASER-Rating-8-VeryGood Rating (8) Very Good – Slight Centerline Crack
PASER-Rating-9-10-Excellent Rating (9-10) Excellent

What are the major causes of pavement distress?

Asphalt deterioration generally has two main causes: environmental/weather impacts and structural damage from repeated traffic overloading.

USI encourages Local Public Agency Personnel to be a part of their PASER management system and have the ability to use the tools necessary so that everyone can KNOW THY ROADS.

USI has already helped multiple LPA clients implement a PASER management system, and can help you satisfy that requirement by implementing a PASER system for your jurisdiction. If you would like to learn more contact your local USI Business Development Professional, or E-mail us at postoffice@usiconsultants.com for further information. Having the tools to manage your pavement inventory helps YOU make better decisions on roadway rehabilitation and fixes!
