Abstract
There have been increasing demands to use bright color pavements for
elementary school zones, giving a warning sign to drivers and protecting the
children. This study was initiated to investigate the applicability of color flexible
concrete pavement (CFCP) for elementary school zones in South Korea. Color
flexible pavement has been applied to non-motorway pavements, such as
pedestrian and bicycle roads. This paper presents the engineering properties of
color flexible concrete pavement used for motorway pavement of elementary
school zones. A commercial polymer of low-density polyethylene (LDPE) was
used to modify the transparent binder and to increase the performance
characteristics of color flexible concrete pavement. Waste paper was used to
prevent the binder draindown of gap-graded mixture. Evaluation of the mixtures
included the following testing procedures: Marshall stability, indirect tensile
strength (ITS), and permanent deformation. The results from this study showed
that 1) the color asphalt concrete mixtures used in this study had nearly the same
quality in engineering properties when compared with conventional asphalt
concrete mixtures, and 2) there have been no apparent problems in application of
color flexible pavement in the field, especially in the elementary school zones.
Keywords: safety, elementary school zone, CFCP, flexible pavements.
1 Introduction
In general, there is heavy traffic in the vicinity of elementary schools during the
start and end times of school sessions. As children are vulnerable road users with
limited experience using the roads, it is a principal concern to keep elementary
