TECHBRIEF Friction Angles of Open- Graded Aggregates

(6) Each aggregate was tested at normal stresses of 5, 10, 20, and 30 psi, which is a typical stress range for wall and bridge applications, to determine the fric-tion angle. Note that before testing, the LSDS device was calibrated for displacement and shear resistance; the load cells measuring normal and shear force were also calibrated. Results
