While the Alaska : Flexible Pavement Design software has been in use since 2004, there is no. Life cycle cost analysis is a key part for selecting materials and techniques that optimize the service life of a pavement in terms of cost and performance. Inclusion of LCCA in Alaska flexible pavement design software manual. The objective of the program was to evaluate the performance of pavements incorporating new or timely design concepts and to.
This manual includes identification and classification of.Ī program of construction and the performance evaluation of three major Virginia experimental flexible pavements is reported. This design manual presents the results of a detailed study to identify and design flexible and composite pavement configurations which will perform as premium or "zero-maintenance" pavements. Volume 2, Design manualĭOT National Transportation Integrated Search It is intended as a guide to the user on the type and form of information required as input to the procedure and contains all elements necessary for the user to prepare designs for flexible pavement overlays.įlexible and composite structures for premium pavements. This user manual outlines a procedure for the design of asphaltic concrete overlays on existing asphaltic concrete pavement surfaces. Extensive analyses of the AASHO Road Test flexible pavement data are presented supporting the validity of the proposed concepts.įlexible pavement overlay design procedures. Algorithms were developed relating pavement response parameters (stresses, strains, deflections) to AC thickness, AC moduli, granular layer thickness, and subgrade moduli. Two design criteria are considered: AC flexural fatigue cracking and subgrade rutting.
The procedure is based on ILLI-PAVE, a stress dependent finite element computer program, coupled with appropriate transfer functions.
Mechanical design concepts for convetional flexible pavement (asphalt concrete (AC) surface plus granular base/subbase) for highways are proposed and validated. Mechanistic design concepts for conventional flexible pavements
