This technical memorandum describes an investigation (1) to measure the change in pavement surface friction at three hours and at three days after application of six rejuvenators as fog seals and (2) to compare friction values obtained using the California Skid Tester (CST), the British Pendulum Tester (BPT), and the Dynamic Friction Tester (DFT). Statistical correlations among the CST, BPN, and DFT are presented.
