Abstract

Concrete pavements as concrete road slab, appear as a strong alternative
for flexible superstructures especially because of their low cost for
maintenance and repair and the high performance they show under heavy axle
loads. The design of these concrete road slabs is quite different from the traditional
concrete and reinforced concrete structures’ design. In the design for this
kind of pavements, traffic conditions should be defined properly and considered
an addition to the concrete and platform properties. There have been designing
methods developed based on both experimental and mechanic foundations for
concrete pavements. The most important ones of these methods are AASHTO (1993)
and PCA (1984). In both design methods, it’s significant to know the maximum
deflections and maximum strains the vehicles’ loads cause on the pavement. The
calculation of this maximum deflections and maximum strains can be done via the
finite element method or the closed formulas which have been developed by
Westergaard. In this study, a user-friendly software has been developed based
on AASHTO 1993, PCA 1984 design methods and Westergaard formulas. Thanks to
this software, the user who wants to design the concrete pavement as concrete
road slab can obtain the essential parameters automatically by entering the
required data for the design.
