Preservation Questionnaire Survey Form
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.

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.
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.

23. Does your agency consider user costs in the treatment selection process for preventive maintenance applications? (Check
the one answer that is most representative.)
If you answered yes, proceed to a. If you answered no, skip to b.
No
Yes
a. Are user costs quantified numerically in your treatment selection process?
No
Yes
b. Does your agency have plans to begin considering (or incorporating) user costs in the treatment selection
process?
No
Yes. Please explain: _______________________________________________________________________________
24. There are a number of reasons why agencies may not be performing pavement preservation on high-traffic-volume
roadways. Please prioritize the additional guidance that you feel is needed for the successful implementation of preser-
vation strategies on high-traffic-volume roadways.
1 = No guidance needed
2 = Some guidance
3 = Significant guidance needed
_____ Other agency experience with treatment _____ Typical noise associated with treatment
_____ Experienced contractor availability list _____ Treatment production rates
_____ List of material availability _____ Time needed before trafficking
_____ Typical traffic control requirements _____ Typical treatment costs by region
_____ Typical closure time information _____ Applicable traffic volumes
_____ Durability/expected treatment life _____ Appropriate climatic regions for treatments
