ISSUE
The Air Force
initiated several Design-Build (D/B) airfield pavements projects
in the last couple of years. Long-term performance of these projects
cannot be predicted at this time. We do know that there is general
concern about premature deterioration of traditional Design-Build
projects because of the tendency to design for lowest initial
cost.
RESEARCH
Perform a search
of D/B airfield pavement projects and investigate the pros and
cons resulting from using the concept on airfields. This will
involve interviews with base staff. Determine the reason for any
premature deterioration of D/B airfield pavements. Assess the
cost effectiveness of D/B pavement projects given the project
costs and associated pavement performance to date. Coordinate
with Air Force design and construction agents and create a standard/draft
Request for Proposal (RFP).
BENEFITS
Will provide an
assessment of existing D/B pavement projects, their effectiveness
from a cost and time standpoint, and process and/or design changes
needed to improve pavement performance under the D/B concept.
PRODUCT
Two
final products will be prepared by this project. First, the researcher
will prepare a report documenting the project interviews, lessons
learned, and performance evaluation results of airfield pavements
constructed using D/B techniques. Second, the researcher will
provide a standard/draft RFP for use in the industry for D/B pavement
projects.
