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

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

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

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

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

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

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

9. Current solutions you typically use to remedy rutting:

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

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

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

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

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

15. Number of Respondents from the State

16. Perception of Low Volume Traffic in the District

17. Percent of Roads is Considered Rural in Districts

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

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

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

21. Common Distress Found at Intersection

22. Results of the Most Probable Causes of Distress

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

24. Results Showing If Drainage is Considered at Intersections

25. 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.

26. Typical Remediation Strategies that are Considered

27. Remediation Process and Unit Cost Associated with Each Process

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