About the research
Research objective: Increased concern for environment and worker safety requires that alternatives be found to avoid working with hazardous materials. An alternative for the calibration method using mercury in Section 4 of AASHTO T 153/ASTM C 204 is needed.
The objective of this project is to add an alternative method to AASHTO T 153. The new method must not use hazardous materials and be safer to use than the current method while maintaining the accuracy and precision of the current method.
