  1. Project TX 0-5566 District Questionnaire (October 16 2008) Strategies to Improve and Preserve Flexible Pavement at Intersections UTEP - Soheil Nazarian • Imad Abdallah

  2. Do your pavements experience distress at the intersections of low volume roads?

  3. Do your pavements experience distress at the intersections of low volume roads?

  4. Do your pavements experience any type of distress at the intersections of low volume roads?

  5. What the severity level at the intersections of low volume roads?

  6. What distress types are common at your intersections on low volume roads?

  7. If rutting is an issue at intersections, please select probable causes: (check all that apply)

  8. Current solutions you typically use to remedy rutting:

  9. Typical Performance Period for Selected Remediation Strategies (Rutting)

  10. Typical Performance Period for Selected Remediation Strategies (Cracking)

  11. Typical Performance Period for Selected Remediation Strategies (Pushing)

  12. Typical Performance Period for Selected Remediation Strategies (Shoving)

  13. Project TX 0-5566 District Questionnaire 2 (April 2009) Strategies to Improve and Preserve Flexible Pavement at Intersections UTEP - Soheil Nazarian • Imad Abdallah

  14. Number of Respondents from the State

  15. Perception of Low Volume Traffic in the District

  16. Percent of Roads is Considered Rural in Districts

  17. Results of Whether the Districts Have a Count on the number of intersection in the District

  18. Results of Whether the Intersection are Treated Differently Than the Remaining Part of the Road

  19. Results of Whether Road Condition are Better Away From the Intersection

  20. Common Distress Found at Intersection

  21. Results of the Most Probable Causes of Distress

  22. Results of Pavement Layer That Most Probably Contribute to Distress

  23. Results Showing If Drainage is Considered at Intersections

  24. Type of Preliminary Information used for selecting best Remediation Strategies 1. In some cases.2. If possible install signs that indicate the presence of stop.3. And cross traffic especially truck traffic.4. Where the intersection is at…to see if the problem is continual throughout the stretch or not.5. Review existing pavement structure and whether it was stabilized or not.6. (1)Review old set of plans and generally core to determine typical sections, (2) Check with maintenance section for repair history/problems at location.7. Low heavy loads.8. Buy the sign crew field book.9. Whole intersection.10. 55MPH.11. Hot Mix 2 in CMHB.12. We do all of the following by having cores and traffic analysis done.

  25. Typical Remediation Strategies that are Considered

  26. Remediation Process and Unit Cost Associated with Each Process

  27. Additional Information Gathered for Design and Construction 1. Generally FWD.2. DCP, Tri-Axle.3. FPS 19.4. Remaining life analysis from TTI.

  28. Selection of hot Mix for Pavement Remediation

  29. Selection of Base and/or Treatment for Pavement Remediation

  30. Decision of How and When to Improve the Subgrade

  31. Process of Selecting the Appropriate Drainage System

  32. Practices Employed for Site Preparation

  33. Practices Employed for Construction Practices

  34. Practices Employed for Scheduling Repairs

  35. Quality Control measures to Implement Remediation Methods

  36. Decision Making Process in Terms of Selecting Candidates for Maintenance and Rehabilitation

  37. Type of Information Gathered to Select the Maintenance or Rehabilitation Method

  38. Results of whether Life cycle Cost Analysis is Used in the Decision/Selection Process

  39. Cost or Expected Life in Decision Making

  40. Budget Range for Maintenance and Rehabilitation

  41. Treatment Flexible Pavement Treatment Selection Options (Bryan District) Distress

  42. Flexible Pavement Treatment Selection Options (Atlanta District)

  43. Flexible Pavement Treatment Selection Options (Laredo District)

  44. Flexible Pavement Treatment Selection Options (Abilene District)
