I have been asked to investigated potential failure mechanisms of
bituminous or pitch fibre (Black) pipe installed as sewer laterals.
It is my understanding that this pipe was extensively used in the UK and
North America until the late 1950's or early 60's.
Does anyone know of any references associated with the use of pitch fibre
pipe? Any help would be appreciated.
Thanks in advance.
