in pavement requirements. The TSMCX generally maintains one or more IDT contracts with A-
E firm(s) experienced in design of pavements. These IDT contracts are available for use by
Corps Districts. Knowledgeable, experienced design staff, whether in-house or A-E, are critical
for successful concrete pavement projects. Typical concrete pavement design teams consist of
(several roles may be combined in one person):
Pavement layout engineer
d. Geotechnical report. Geotechnical reports are prepared on most military projects as a
record of foundation investigations and foundation design for that project. TM 5-822-5,
"Pavement Design for Roads, Streets, Walks, and Open Storage Areas," discusses preliminary
investigations for these types of pavements. TM 5-825-3, "Rigid Pavements for Airfields," covers
preliminary investigation, subgrade considerations, base courses, soil stabilization or modification,
and evaluation of foundation support. The results of these and related investigations should be
presented in the geotechnical report. TM 5-825-1, "General provisions for Airfield/Heliport
Pavement Design," presents geotechnical information that must be included in the design analysis
for these types of pavements.
e. Materials studies. Early in the design period, concrete materials studies are required to
determine the availability of aggregates and allied materials, the quality and durability of the
aggregates and other materials, and the properties of these materials in concrete. TM 5-822-7,
"Standard Practice for Concrete Pavements," describes concrete materials for pavements, as well
as requirements for "approval of aggregates." TM 5-825-1, "General Provisions for
Airfield/Heliport Pavement Design," describes materials information that is presented in the
design analysis. Information from these studies is generally presented in an office report.
Conclusions and recommendations from these studies include the design material properties for
the concrete pavement, and provide the basis for specification preparation for the concrete
pavement. Description of typical contents of the office report follow.
(1) Project description and concrete pavement requirements. This includes a summary
description of the pavement to be constructed, including site requirements, dimensions, quantities
of concrete and materials, and special logistical problems.
(2) Environmental conditions. This section contains information on climatic and other
environmental conditions at the site which may affect the concrete, including rainfall, hot weather
conditions, cold weather conditions, deicer applications, snow plow usage, sulfate attack, and
possible jet blast conditions.
