Appendix B. Survey Questionnaire and Responses B 1

Part A: Survey Questionnaire April 2018 For NCHRP 1-57A Developing Standard Definitions for Comparable Pavement Cracking Data The research team at Oklahoma State University (OSU) has been tasked by NCHRP to carry out the project “Developing Standard Definitions for Comparable Pavement Cracking Data”, NCHRP 1-57A. We need your help to develop standard definitions for pavement cracking data by participating in this survey. The results from this survey will guide the development of the new cracking definitions, which will assist state highway agencies in understanding the collected cracking data and pavement conditions, applying the definitions for both pavement design and management, and taking advantages of new data collection and processing technologies to fulfill current and new state and federal requirements. After receiving your survey data, members of the research team may contact you for additional information or clarifications. Your efforts and assistance are highly appreciated!

No cracking is rated for saw and seal until deterioration is present. Other (please describe the method used by your agency): Q53 How does your agency consider slab patches and partial replacements in reporting of pavement condition? Patching is rated for patches <15 SY, spray patching is difficult to rate when patched area is not easily determined. permanent concrete patches are not rated, but temporary asphalt patches on concrete are rated.

Yes Page 10: Part II: Cracking Definitions Page 11: Part III: Wheel-Path Definitions Q56 What’s the width(s) of wheel-paths (Zones B & D) in your agency? this varies practically speaking based on lane width and can be determine when performing manual survey. It has not been determined the appropriate single width wheel path for automated distress classification. 18" to 22" wide for 10 to 12' lane is minimum, may be up to 36" Survey Questionnaire for NCHRP 1-57A: Developing Standard Definitions for Comparable Pavement Cracking Data SurveyMonkey B 107

Q57 What’s the width of Zone 3 in your agency? 6'-8" to 7' would be anticipated, there is more wander in wider lanes which makes a wider wheel path and narrower zone 3 Q58 If your agency specifies any standard width(s) of Zone 1 and Zone 5, please provide: anticipated 0 to 10" each depending on lane width. I would anticipate using the algorithms with automated processing to identify lane markings and associate given widths, this would vary based on the markings found Q59 Has your agency implemented AASHTO PP 67 for cracking quantification? No Page 12: Part IV: AASHTO PP 67 Applications Q60 What are the benefits from the implementation of AASHTO PP 67? Automated distress classification has not been implemented in Ohio, automated HPMS distresses are beginning to be reported but have no comparison or checks as they relate to use within the department. Q61 What challenges does your agency face during the implementation of AASHTO PP 67 to meet various data needs such as HPMS, PMS, and Pavement ME Design? PMS and PMED would require different classification and additional distresses not covered by PP 67. Without Automated implementation, challenges are unknown at this time. Q62 What are your suggestions for the revision of AASHTO PP 67? It would not be expected that PP 67 would provide the level of detail needed within a state for pavement management. For example, pattern cracking would include alligator and block cracking. while alligator could be defined within the wheel path zones, block cracking is not and would not be easily differentiated with measures of length and width within each section. Average width within each section may also not be the best measure for any crack, an agency may need to quantify length within certain categories of width in order to make decisions. I see PP 67 more as a uniform requirement for HPMS submittal not really a uniform requirement for actual agency pavement management use. Page 13: Part V: General Comments Q63 What are your opinions and expectations for a new cracking protocol for fully automated system in next 10 years? A new cracking protocol may be useful for HPMS, but I would expect that regardless of timeframe a standardized protocol would likely not be detailed enough for some or could be too detailed for others for their pavement management uses. I would be surprised if a standardized protocol, once decided upon, will cover all agency needs.

It is going to be difficult to switch from a 2.34' wheelpath to 39" wheelpath. I find it hard to believe that some of the federal initiatives (Mechanistic-Empirical design, MAP-21) do not draw any distinctions based on crack severity (width). The severity of the crack has a strong effect in the formulas we use to convert raw cracking data to index values that we use to manage our pavements. I hope that new protocols will be built around the capabilities of automated crack detection; it is very effective when coupled with thorough QA/QC.

On JCP and CRC, Low <0.25 inches, Medium, >=0.25 with no spalls, High, >=0.25 with spalls Q26 Does your agency collect alligator/fatigue cracking data? Yes Q27 What is your agency’s definition of alligator/fatigue cracking? Fatigue cracking consists of longitudinal cracks located in either wheel path. Fatigue cracking is only found on flexible pavements. Fatigue cracking may also occur within the area where a blowup has been repaired. A blowup is an isolated area where a bump or upward movement of the pavement surface has formed at a transverse crack. Although the blowup may have been repaired, cracks may be evident. For an example of a repaired blowup, please see EXHIBIT B ON PAGE 7. Cracks that have been sealed shall not be rated, except when the sealant has failed. Any crack that extends beyond the sealed area shall be rated. For an example of a sealed crack, please see EXHIBIT A ON PAGE 6. Cracks shall be rated, quantified, and reported according to the appropriate distress type and level as described in III.b. Fatigue cracking is observed in any or all of the following forms: 1. Longitudinal crack(s) in either wheel path on flexible pavements only. 2. A series of interconnected, transverse and longitudinal cracks in either wheel path forming a series of polygons or blocks. In the most extreme case, the individual polygons or blocks can become loose and develop into "potholes". Q28 Transverse and longitudinal cracks can span wheel- path(s) and non-wheel-path(s). Does your agency count the portion of a transverse or longitudinal crack in the wheel-path(s) as alligator/fatigue cracking? Yes Q29 What is the minimum length or area of an alligator/fatigue crack recorded in your agency?

Q31 What is your preference: elimination of alligator/fatigue cracking from protocols, instead consideration of all cracking located in the wheel-path(s) as load-associated? No Q32 How does your agency rate severity levels for alligator/fatigue cracking (check all that apply)? Others (please describe the method used by your agency): Low: Consists of either of the following two cases: i. One or more longitudinal cracks, of any width, that occurs solely in the wheel paths with few or no intersecting transverse cracks. These cracks may or may not have patching and/or pop outs. ii. Intersecting longitudinal and transverse cracks that form large polygons or blocks greater than one square foot and occur solely in the wheel paths. Note: Any cracking that extends outside of the wheel paths shall be rated as Random (Miscellaneous) cracking; Medium: Consists of interconnected longitudinal, diagonal, and short transverse cracks that occur solely in the wheel paths whose crack width ranges from hairline to 0.25 inches. These cracks form a network of polygons or blocks. Some spalling may be observed; however, there will be no loose pieces of asphalt nor will there be any indications of "potholes." The average size of the pieces formed by the cracks will be less than one square foot. High: Consists of interconnected longitudinal, diagonal, and short transverse cracks that occur solely in the wheel paths and whose crack width is generally greater than 0.25 inches. These cracks form a network of polygons or blocks. These cracks are generally spalled and some potholes may be present. The size of the pieces formed by these cracks will be less than 1 square foot.
