"The jaw-cone-VSI system with dry screening enabled us to produce our existing product mix plus the asphaltic material
with a very good cubicle shape," Reid said.
Oil in bitumen and asphalt was found to have a detrimental effect with regards to the quality of the asphaltic material
as it leads to reduced adhesiveness to the aggregates leading to stripping and ravelling (Villanueva et al, 2008 and Katamine 2000).
Ductile iron pipe is coated on the outside with asphaltic material
. In areas with severely aggressive soils, a polyethylene tube or sheet encasement has proven to provide highly effective protection and is covered by ANSI/AWWA C105 standard.

Every year, a large quantity of milled asphaltic materials
is generated from the rehabilitation and maintenance work carried out by the DoT and other government and private entities.
The DoT project aims to develop procedures and operational policies as well as technical specifications for management of pulverised asphaltic materials
produced from roads and pavement maintenance works.
