About the research
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.
