  5. 5.  Roadway condition survey: A condition survey is the process of collecting data to determine the structural integrity, distresses, skid resistance, and overall riding quality of the pavement. Provides the most valuable information for roadway performance analysis Vital in order to forecast roadway performance, anticipate maintenance and rehabilitation needs Establish maintenance and rehabilitation priorities, and allocate funding 5

  7. 7. Scope Geometric Design of Roadway Dynamic Traffic Management Traffic Control Purposes Traffic Planning Improvement of Level of Service of the Road 7
  8. 8. Purpose of roadway condition survey To make a summary of the overall condition of the roadway To make an historical record of roadway performance and maintenance practices To justify warrant of traffic control devices To study effectiveness of introduce schemes diagnosing given situation and finding appropriate situations 8
  9. 9. 9 Alligator Cracking It is a structural pavement failure that may be caused by traffic overload, inadequate design thickness, base or sub- grade failure, poor drainage, or a combination of these factors. Rutting Rutting is a surface depression that typically occurs in the wheel path(s) or at the edge of the pavement. Rutting represents a structural failure. Patching Patching is only an indication of the amount of surface area that has received some type of maintenance repair. Some Important Definitions
  10. 10. 10 Raveling Raveling is identified by the loss of aggregate particles from the pavement surface. Random or Grid block cracks Random block or grid block cracks divide the pavement into rough rectangular or poly-angular pieces. Transverse cracks Transverse cracks are those considered to extend greater than ¾ the width of the pavement generally perpendicular to the centerline of the pavement. Some Important Definitions
  11. 11. 11 Bleeding Bleeding is a film of bituminous material on the pavement surface that creates a shiny, reflective surface. Bleeding is caused by excess asphalt cement in the mix and/or low air void content. Skid Resistance Skid resistance, or surface friction, indicates the ability of the pavement surface to provide sufficient friction to avoid skid related safety problems. Some Important Definitions
  12. 12. 12 Pedestrian Refuge Island Crosswalks may also include pedestrian refuge island Potholes Potholes usually develop in a surface that is either cracked, raveled or both. Some Important Definitions
  13. 13. 13 Zebra Crossing Its distinguishing feature is alternating dark and light stripes on the road surface, from which it derives its name. A zebra crossing typically gives extra rights of way to pedestrian. Ladder Crossing Some Important Definitions

  15. 15. 15 Manual Survey Methods Walking Survey :  Provides the most precise data about the condition of the roadway.  surveys are completed by a rater who is trained to rate distresses. Windshield Survey :  survey is completed by driving along the road or on the shoulder of the road.  Allows a greater amount of coverage in less time. Walking + Windshield Survey :  Good method to achieve detailed pavement distress data
  16. 16. 16 Automated Survey Methods VIDEO CAMERA :  Observe service condition of roadway. AUTOMATED PAVEMENT CONDITION SURVEY VEHICLE DISTANCE MEASURING INSTRUMENT  Electronic instruments that precisely measure distances  They are easy to install
