Evaluation of the Effect of the Production Process in Quality Parameters of Polymer Modified Performance Grade Binders: A Case Study

In India, most of the agencies started to use Polymer Modified Bitumen (PMB) as a binder in the bituminous layer due to its higher performance, India’s climatic conditions, and the increment in traffic loads. The variability in quality parameters of polymer-modified performance grade binder of a particular grade has been observed even if the key parameters like source and grade of base binder, and source and dosage of polymer are kept constant. The study's primary aim is to compare the variability in quality parameters of the PMB produced at two different production units and find the permissible range of quality test results in the modified bitumen while following a standard production methodology and standard laboratory set-up. Detailed statistical analysis was undertaken for 200 batches of PMB samples. Result of the study indicates the importance of automation in production plants as well as quality control equipment. Production unit 1 (PU 1) with more automation showed lesser variability consistently across all quality parameters of the PMB as compared to production unit 2 (PU 2) which had more manual processes in the production. Also, the laboratory set-up in terms of availability of automated equipment, temperature control, and skilled technician, of PU 1 was better as compared to PU 2 which played a key factor in the variability of quality parameters. The study’s key takeaway is to highlight the importance of creating an environment of quality consciousness to produce performance grade binders for long-lasting pavements.
