66 NATIONAL COOPERATIVE HIGHWAY RESEARCH PROGRAM AUTOMATED PAVEMENT DISTRESS COLLECTION TECHNIQUES QUESTIONNAIRE You are being asked to help in developing a synthesis on Automated Pavement Distress Collection Techniques by providing information on your agency. We are confident that the synthesis will become a valuable resource document for you and others contemplating the collection and management of pavement condition data. The synthesis will focus on automated pavement condition collection techniques, specifically for pavement cracking, roughness, rutting, and faulting. The objective is to document how agencies conduct automated data acquisition and processing. This questionnaire has been simplified to the extent possible given the nature of the material. In some instances it may be best that the consultant, Ken McGhee, talk with individuals within your agency. For that reason, there are several cases where you are asked to provide additional contacts, if appropriate. In other instances, copies of protocols, standard operating procedures, contracts, or other documents may be the best response, and the questionnaire often suggests that option. Please call or e-mail the consultant if you have trouble with the questionnaire. The consultant will call or e-mail you if he needs additional information. Respondent Information Please provide the information requested below for the person completing this questionnaire (if you received the question- naire and someone else is in a better position to respond, please forward the document to that person). Agency: Name: Title: Street address: City: State: Zip code: Telephone: Fax: E-mail: Return Information Please return the completed questionnaire by e-mail, fax, or by land mail with any supporting documents by February 10, 2003 to: Kenneth H.

67 PART IâPRELIMINARY QUESTIONS 1. Does your agency collect pavement distress data? [Includes any of the following: surface distress (cracking), pavement ride quality (IRI), pavement rutting, or joint faulting.] Yes No If the answer is âYes,â please proceed to the next question. If the answer is âNo,â please return the questionnaire as directed above and thank you for your time. 2. Does your agency use or plan to soon use automated pavement distress collection technologies?
