Global environmental consciousness and high disposal cost of glass wastes have influenced the potential
use of recycled glass fibres (RGF). The characteristic strength of RGF can be improved and therefore reuse
especially in construction industry appropriate to its intended purpose. In this paper, series of experiments
were conducted to investigate the mechanical properties of RGF derived from electronic grade
glass (E-glass) scraps. The effect of the RGF inclusion in soil strength parameter improvement was also
studied by considering different types of soil media, vertical pressures and coating effect. The results
show that the mechanical properties of RGF are slightly lower than the original fibres. However, in the
presence of acrylonitrile butadiene styrene (ABS) coating, the interfacial friction between soil particles
and fibres surface is increased due to the increase in their surface area of contact thus, improving both
cohesion value and the angle of internal friction values of the reinforced soil. Likewise, failure envelopes
of various soil media reinforced with RGF were observed to be enhanced significantly. The findings from
this research show that the presence of RGF reinforcement in reinforced soil leads to a significant
increase in the shearing resistance and internal friction angles of soil media. Furthermore, soil fibre
matrix deformation is fairly retained, as a result of interlocking action between soil and glass fibres
which mobilises the resistance to horizontal shearing stresses.
