| description | Millions of ringgits have been spent annually for road maintenance. The causes of road
problems may be due to incorrect selection of pavement material. The study shows that
there is the tendency for using the same pavement material for the whole stretch of a
project. Some important factors that affect pavement material were not considered by
road designers, because there is no systematic pavement material selection system
available. At present, road designers refer to some road design standard procedures
which are not updated consistently and there is little exposure to some other pavement
materials. A systematic pavement material selection based on expert guidance to guide
the road designers is needed.
This thesis looks into the first development of a Road Construction Material Selection
System (RC-MSS), based on the outcomes of questionnaires from the selected pavement
experts using the Friedman’ statistical analysis and documented sources. The study also looks into what the practitioners want if a pavement material selection system is
developed. The survey shows that pavement materials were governed by soil conditions,
expected load repetitions and geometric features of vertical gradient and horizontal
curvature. Besides, the selection of the appropriate construction materials for the
various layers for various traffic-loading under the type of terrains such as flat, rolling
and mountainous was incorporated as important parameters. All these factors were
found to be indispensable in the formulation of a material selection system for road
construction.
In the Friedman hypothesis testing of this study, it was found that there is significant
difference in terms of durability, performance and ease of construction from each
suggested pavement material in nine site conditions out of 30 site conditions. Multiple
comparisons have been used to the rejected null hypothesis to determine which materials
were significantly different in these nine rejected null hypothesis site conditions
respectively. Positions were then given to the pavement materials based on the outcomes
from the multiple comparisons method. The factors were then incorporated into
developing of the specific rules of the system framework and the 30 site conditions were
associated with the documented source and used as knowledge database for the system.
In order to make the system user-friendly, compatible and flexible, the system was
developed into the software using a programming language. RC-MSS developed
interfaces are easy to use and have non-complicated procedures. The user can go straight
to the output fast. The system can help the user in better decision-making of pavement
material selection as it provides more feasible alternative materials. |
