Quality Assurance/Quality Control
The polymer modified bitumen Quality Control Quality Assurance Program is a
comprehensive program designed to verify, assess, and track the quality of polymer modify
bitumen delivered to projects and maintenance operations. It is also used as a means for
qualifying Producers to provide polymer modify bitumen in this capacity.
Various quality control tests in different steps of the production process, including on the
raw materials, during product manufacturing and finally on the finished product are
performed to control the quality and specifications of the bitumen produced in this company.
Various bitumen tests in the lab are carried out under certain conditions which are strictly
controlled and standardized .The complete test instructions are described in the related
technical regulations such as AASHTO & ASTM regulations.
These regulations should be strictly observed in the manufacturing process so that the
results could be reliable and useful. In order to carry out the tests in different steps of quality
control i.e. on the raw materials, product manufacturing and finally on the finished product,
considering required facilities for the quality control lab is essential.
