• Abstract:
  This feature was implemented to determine if an applied fog seal to chip seal (FSCS) would extend the service life of the pavement treatment (chip retention) compared to the conventional practice of a chip seal (seal and cover). The chip seal application used CHFRS-2Pemulsion and MDT type 3 chips. The fog seal applied was a CSS-1H. There was no planned control, however Taft – West, the section to the west of Exit 5 – East, was constructed the year prior with CRS-2P and MDT type 2 chips. The evaluation location is a tight canyon through the mountains and experiences extreme weather conditions that increases maintenance activities and limits the effectiveness of past pavement preservation treatments.
