Moisture Damage in Fibre Reinforced Bituminous Road Materials

The presence of water in the
bituminous layers of a pavement structure often
produce serious distress, reducing it’s
performance and increasing the maintenance
costs. Experience has shown that many factors
such as bitumen characteristics, aggregate
properties, mixture design, construction
procedures, environmental conditions and traffic
loading contribute to the severity of the
condition. The influence of water on the service
performance of bituminous pavements has been
the subject of extensive research. This paper is
based on a laboratory work and addresses the
damaging effect of water in polymer fibrereinforced
bituminous mixtures.
