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
6. 6. Objective • Geometric layout of roadway • Geometric layout of intersectionGeometric condition • Road surface condition • Location and width of side road • Pedestrian crossing facilities Operating Condition 6
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
14. 14. 14 1. Walking Survey 2. Windshield Survey 3. Walking + Windshield Survey Manual 1. Video Camera 2. Automatic Survey Vehicle 3. Distance measuring instrument Automatic Methods of Data Collection
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

41. 41. Recommendation  Geometric condition • Pedestrian Refuge Island Should not too high • The geometric layout of the roadway was not exactly designed following road standards. There was a continuous lack of symmetry throughout the length of the road, especially at the intersections 41
42. 42. 42 Recommendation  Operating condition  Extra facilities for blind peoples and peoples who use wheelchair should be provided  The footpath should be cleared, clean and in good condition so that pedestrian can walk and use footpath properly  Proper signs and markings on road is highly recommended  Retro reflective sign post panels should be provided  Roadside parking should be prevented and prohibited  U-turn should be restricted and minimized
43. 43. 43  Non Motorized Vehicles (NMV) Shouldn’t Be Allowed In This Road  Road Side Parking Should Be Banned or Toll May Be Collected To Discourage Parking Recommendation  Road Side Non-motor activities Should Be Banned or Prohibitted
44. 44. 44  Scattered And Haphazard Pedestrian Crossing Should Be Discouraged And Prohibited  Foot Over Bridges Should Be Constructed At Important Points For Pedestrian Crossings  Zebra Crossing Should be Provided Recommendation
45. 45.  Limitations  Limited and unskilled enumerators.  Time and Recourses was Limited  Insolent Surveyors  Manual method of survey, which is unreliable  Proper enforcement of traffic regulation is not obtained.  Professional photographer was not available 45
