Abstract

Pavement is one of the main features in cities and urban areas that contribute to the Urban
Heat Island (UHI) effect. The urban areas are more affected by this condition compared to the rural areas due
to the extensive built environment and lack of vegetation cover. Many studies have reported that the shear
strength of sandy soil was improved by using the microbial-induced calcite precipitation method and most of
the experimental work on microbial cementation utilized cultivated culture of ureolytic bacteria for calcium
carbonate formation. However, our previous study has demonstrated that vege-grout from vegetable waste
can also induce bio-cementation due to the presence of microbial activity in the vege-grout. Following this,
the study has been expanded to investigate the feasibility of bio-cementation from vege-grout as a coating
material to reduce surface temperature. A mixture of the coating was developed using vege-grout as the main
composition. The mixture was then applied on the surface of the interlocking paver and left to cure at room
temperature for seven days. Surface temperature was measured using an infrared thermometer and
thermographic camera. Results showed that the surface temperature of vege-grout coated paver was reduced
by 4-5 o
C compared to that of control. The outcome of this study suggested that vege-grout has the potential
to be explored as a component for coating material that can reduce surface temperature.
