106 Introduction The practice of pavement preservation in general and preventive maintenance in particular is a growing trend among trans- portation agencies around the United States. Over the past decade alone, a number of state highway agencies (SHA) have created or formalized their preservation programs. At the same time, other agencies that might have been practicing preser- vation for a longer time have extended their programs to cover a greater proportion of their pavement network than ever before. Still other agencies are today in the process of creating formal preservation programs. While many agencies are in the process of formalizing, extending, or developing their pavement preservation programs, there is a need for further information regarding the use of preservation on high-traffic-volume roadways. The practices used on these facilities are viewed by some as not as widespread or well documented as on lower-volume roadways. The Strategic Highway Research Program 2 (SHRP 2) Renewal Project R26 is addressing the need for this important infor- mation in the following manner: • Synthesizing the current state of the practice for preservation approaches for high-traffic-volume roadways; • Developing guidelines on pavement preservation strategies for high-traffic-volume roadways; and • Identifying promising pavement preservation strategies for application on high-traffic-volume roadways that might not commonly be used. Purpose of Questionnaire The purpose of this questionnaire is to obtain information on current pavement preservation practices for high-traffic- volume roadways from North American and international practitioners. Techniques used for lower-volume roadways may not be appropriate for high-traffic-volume roadways, because as less time is available to construct the treatments and night work may not be feasible. Responses collected from this questionnaire will be used to develop a comprehensive summary of the current state of practice for both portland cement concrete (PCC) and hot-mix asphalt (HMA) surfaced pavements. The survey results will also be used to develop guidelines for the use of these treatments that can be implemented by pub- lic agencies. You are being asked to complete this questionnaire because of your background and familiarity with your agency’s pave- ment preservation practices. Your response is very important. It will lead to improved guidance on the use of pavement preservation for high-traffic-volume roadways, which in turn should contribute to improved pavement performance and lower costs to maintain these important pavements. If, however, you feel that someone else in your organization is more qualified to respond to this request for information, please pass this on to them. Thank you in advance for your assistance. A P P E N D I X B Preservation Questionnaire Survey Form

107 Questionnaire Respondent Information Please provide some general information about yourself and your experience with pavement preservation: Name ___________________________________________________________________________________________________________ Title ___________________________________________________________________________________________________________ Address ___________________________________________________________________________________________________________ Phone ___________________________________________________________________________________________________________ E-mail ___________________________________________________________________________________________________________ Pavement preservation experience/background (e.g., I have been involved in . . . ; responsibilities in pavement preser- vation include . . .): Definitions Used in the Survey Several terms are used throughout this questionnaire. The following definitions are provided for the sake of consistency and not as an attempt to impose on an agency a specific definition of any of these terms. Pavement Preservation—A program employing a network level, long-term strategy that enhances pavement per- formance by using an integrated, cost-effective set of practices that extend pavement life, improve safety, and meet motorist expectations. Pavement Preventive Maintenance—A planned strategy of cost-effective treatments applied to an existing roadway system and its appurtenances that preserves the system, retards future deterioration, and maintains or improves the func- tional condition of the system (without increasing the structural capacity). Preventive Maintenance Treatment—Any individual maintenance activity that is used in a preventive manner (i.e., applied to a pavement in relatively good condition as defined by the agency), while not adding any structural capacity to the pavement. Examples, of preventive maintenance treatments include crack sealing and joint resealing, fog seals, chip seals, slurry seals, microsurfacing, dowel bar retrofitting, diamond grinding, and combinations of these types of actions. Functional Condition—The condition of the roadway which enables it to provide safe, unimpeded service. Functional condition is measured by factors such as surface distress, smoothness, and skid resistance. The functional condition of a roadway does not include consideration of the pavement’s load carrying, or structural, condition. Contract Maintenance—Contract maintenance is the use of a contract to outsource maintenance activities (either to the private sector or to another public agency) that had been done by the agency itself. Contract maintenance, also known as maintenance-by-contract and privatized maintenance, addresses the transfer of work traditionally conducted by the public sector to the private sector. Warranties—Warranties provide contracting agencies with another level of protection against early contractor failure or default, construction problems, or other performance issues. Simply put, a warranty is an assurance to any agency that the work completed by the contractor was constructed in a sound manner and that it will remain in acceptable condition for a stated period of time. Performance Specifications—The performance criteria should describe the outcome that is being sought from the con- tractor in each year of the contract period and provide the contractor with the autonomy needed to achieve the results speci- fied. When setting the criteria, the agency should ensure that the state goals are achievable over the contracting period: they should be at least as high as the standards observed by the agency itself. Quality Control/Quality Assurance (QC/QA)—Quality control generally refers to testing by the contractor for the purpose of process control and to ensure meeting or exceeding specifications. Quality assurance typically involves testing by the agency or its representative to determine compliance with specifications.

Questions 1. Please provide details of the typical average daily traffic (ADT) values associated with the traffic classifications of low, medium, and high traffic volume for rural and urban roadways in your agency. These classifications will be used as the basis for further questions in the questionnaire. 108 Rural, Low Volume is less than or equal to Rural, Medium Volume range is (e.g., . . . to . . .) Rural, High Volume is greater than or equal to Urban, Low Volume is less than or equal to Urban, Medium Volume range is (e.g., . . . to . . .) Urban, High Volume is greater than or equal to 2. There are a variety of factors that influence the selection of a preventive maintenance treatment. Please rank the follow- ing 18 factors in terms of the level of importance that your agency places on each factor when selecting the most appro- priate preventive maintenance treatment. Not Low Medium High Factor Important Priority Priority Priority Agency experience with treatment     Material availability     Previous treatment failure     Alternate route availability     Safety concerns     Perception     Noise     Work zone     Treatment cost     Traffic volume     Experienced contractor availability     Bias against treatment     Traffic control requirements     Closure time     Liability concerns     Durability/expected treatment life     Production rates     Time before trafficking     Risk associated with treatment failure     Climate

TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-R26-RR-1: Preservation Approaches for High-Traffic-Volume Roadways documents the state of the practice of preservation treatment on asphalt and concrete pavements. The report focuses on treatments suitable for application on high-traffic-volume roadways but also discusses current practices for low-volume roadways.

The same project that produced SHRP 2 Report S2-R26-RR-1 also produced SHRP 2 Report S2-R26-RR-2: Guidelines for the Preservation of High-Traffic-Volume Roadways. The report provides suggested guidelines for the application of preservation treatments on high-traffic-volume roadways and considers traffic volume, pavement condition, work-zone requirements, environmental conditions, and expected performance.

An e-book version of this report is available for purchase at Google, iTunes, and Amazon.
