68 APPENDIX B Interview Questions And Respondents Interview questions were developed to gain information not available from the survey responses. A list was compiled of sur- vey respondents who indicated they were willing to participate in follow-up interviews. Interviewees were asked 16 questions and instructed to provide responses based only on their direct experiences. Interview responses were recorded with a digital recorder and then transcribed or recorded by hand during the interview process. Thirty individuals were selected and asked to be interviewed based on the information they made available in the survey. A total of 25 interviews were conducted, providing an 83% interview response rate. Interviews were conducted over the phone with the exception of two e-mail responses (owing to the intervieweesâ location and language differences). Information gained from the interviews and incorporated into this report includes additional resources, references, erosion control and slope stabilization techniques and tools, best management practices, useful points, photographs, knowledge gaps, and research needs. Interview Questions NCHRP Synthesis Low-Cost Solutions for Road Slope Stabilization and Erosion Control Please read this paragraph before you begin the interview. Hello, my name is Laura Fay/Michelle Akin from the Western Transportation Institute at Montana State University. In the survey for the NCHRP Synthesis Low-Cost Solutions for Road Slope Stabilization and Erosion Control, sponsored by the National Cooperative Highway Research Program under the National Academies, you identified yourself as being willing to participate in a follow-up interview or you were identified by a survey respondent as a potential interviewee. We are seeking your participation in a follow-up interview in which we are compiling information on cost-effective (i.e., low cost), environ- mentally friendly, and sustainable shallow or near-surface slope stabilization and related erosion-control treatments used on low-volume roads. We are seeking information on current practices, best practices, or emerging solutions that are used regionally, nationally, or internationally. This interview will take approximately 10â20 minutes of your time and will ask for you to comment on your direct experi- ence on this topic. Participation is voluntary, and you can choose to not answer any question that you do not want to answer, and you can stop at anytime. May I audio record this interview? If not, I will be documenting all of your answers by handâis that all right with you? 1. Name, title, agency, contact information. 2. Please describe your working experience with road slope stabilization. 3. What road slope stabilization technique do you most frequently use? 4. Based on your experience, what is the most cost-effective road slope stabilization technique? 5. Have you used this method? If so, do you have information (photos, data, design, cost, benefits, limitations, life expec- tancy, etc.) from the implementations that you could share? 6. Based on your experience what is the most sustainable/environmentally friendly road slope stabilization technique? 7. Have you used this method? If so do you have information (photos, data, design, cost, benefits, limitations, life expec- tancy, etc.) from the implementations that you could share? 8. Can you provide us with a description of up to three road slope stabilization projects that you have completed that were both low-cost/cost-effective and sustainable/environmentally friendly? 9. Could you tell us about some lessons learned in road slope stabilization related to the examples you have provided? 10. Are there road slope stabilization techniques/treatments you would never try or use again? Why?
69 11. What do you see as an underutilized tool, material, method, etc., in road slope stabilization? 12. Where do you see gaps in current state of practice of road slope stabilization, or do you see any need for additional research? 13. Could you provide a name of an individual who may be willing to be interviewed on this topic or point us to additional resources or case examples? 14. Would you like to receive an e-mail with a link to the final report when it becomes available? If so, please provide the e-mail address you would like the link to the final report to go to. 15. Comments/suggestions 16. Thank you for your time. May we thank you for your participation by listing your name in our final report?
