PAVEMENT ENGINEERING
CONSIDERATIONS
Topic 611 - Factors In Selecting
Pavement Type
Index 611.1 Pavement Type Selection
The types ofpavement generally considered for
new construction and rehabilitation in California
are rigid, flexible and composite pavements.
Rigid pavement should be considered as a
potential alternative forall Interstate and other
high traffic volume interregional freeways.
Flexible pavement should be considered as a
potential alternative for all other State highway
facilities. Composite pavement,which consists of
a flexible layer over a rigid pavement have mostly
been used for maintenance and rehabilitation of
rigid pavements on State highway facilities.
611.2 Selection Criteria
Becausephysical conditions and other factors
considered in selecting pavement type vary
significantly from location to location, the Project
Engineer must evaluate each project individually
to determinethe most appropriate and costeffective pavement type to be used.
The
evaluation should be based on good engineering
judgment utilizing the best information available
during the planning anddesign phases of the
project together with a systematic consideration of
the following project specific conditions:
•
Pavement design life
•
Traffic considerations
•
Soils characteristics•
Weather (climate zones)
•
Existing pavement type and condition
•
Availability of materials
•
Recycling
•
Maintainability
•
Constructibility
•
Costcomparisons (initial and life-cycle)
The above factors should be thoroughly
investigated when selecting a pavement structure
and addressed specifically in all project documents
(PSSR, PSR, PR, PS&E,etc). The final decision
on pavement type should be the most economical
design based on life-cycle cost analysis (see
Topic 619.)
