Setting up and conducting an analysis session—This section starts with a discussion of
the types of data needed to successfully define all required outputs in the analysis
methodology. The second part of this section walks a user through the analysis tool’s
user interface and the step-by-step procedure for setting up and conducting an analysis
session.

ANALYSIS TOOL CAPABILITIES
The primary purpose of this analysis tool is to enable pavement preservation engineers to
analyze historical preventive maintenance-related performance and cost data in order to
determine the optimal timing of a given preventive maintenance treatment. However, it is
recognized that agencies are in different stages of developing pavement preservation strategies
with many still in the early stages of collecting preventive maintenance-related performance
data. Therefore, flexibility is built into the tool with the inclusion of two parallel analysis
methods (simply referred to as Detailed and Simple methods) used to compare preventive
maintenance timing scenarios. Both analysis types are briefly described below.
ƒ
Detailed Analysis—The main purpose of the Detailed method is to analyze actual (or
estimated) data obtained from monitoring preventive maintenance treatment performance
in the field over time. Because actual field data is expected for this analysis method,
expected condition versus age relationships (before and after preventive maintenance
treatment applications) must be defined by either selecting an equation type and entering
