Abstract:
In many developing countries, including Ghana, disposal of
plastic waste through conventional methods of landfilling,
incineration and communal dumps are not able to effectively
deal with the increasing volumes of wastes generated daily.
Wide-spread occurrence of haphazard littering results in
heavily polluted beaches, rivers, gutters and roadsides with
detrimental impact on human health, ecosystems, critical urban
infrastructure and therefore on productivity and the economy.
Conventional bitumen used as a binder in asphalt roads does not
meet increasing material performance requirements resulting
from rapid increases in vehicular traffic intensity and the
deteriorating effects of climate change (CC), particularly in hot
and humid tropical climates. Polymers are added to conventional
bitumen mixes to increase the stability and durability of roads
and to reduce the cost of construction and maintenance
over the lifetime. This paper is one part of a broader study
exploring alternative uses for waste plastics in the construction
industry as a potential sink for sustainable management of
waste plastics and also for performance enhancement and
cost reduction in the construction sector to support a myriad
of development needs of rapidly-developing economies.
This paper reviews literature on polymer modified bitumen
(PMB) with focus on waste plastic modified aggregates
(PCA). In this study, the history and benefits of using waste
PCA in asphalt are outlined followed by a review of some
studies on using PCA in asphalt and a discussion of its
possible application as a sustainable material for flexible
road construction in a developing economy such as Ghana.
Biography:
Trinity Ama Tagbor is specialized in Natural Product Chemistry. She has many years of experience in research, development and advisory services in construction materials from local sources. Her research areas include innovative construction materials from local sources, Polymer modified construction materials including waste plastic/bitumen composite materials for construction of roads and buildings for sustainability, emulsion and insecticidal emulsion paints from local materials. Her current research is on incorporation of waste materials into construction for cost effectiveness and sustainable management of waste plastic. She is currently a member of committee which is planning to organize a conference on ‘Building Climate resilience of Infrastructure in Ghana’ which is scheduled to take place in Ghana in 2019.
