• Abstract:
  The AHMCT Research Center, together with Caltrans, has been leading a multi-year research effort to develop ; innovative high production crack sealing equipment, which improves safety while reducing costs. The Sealzall ; Machine development project is the latest version of a line of successful longitudinal crack sealing machine prototypes ; developed and deployed with Caltrans on California highways. The program’s key technical element has been the ; application of automation technologies and custom engineering solutions to achieve increased sealing efficiencies and ; to eliminate the workers’ exposure to highway traffic. The preceding Transfer Tank Longitudinal Sealer (TTLS) ; development project produced a prototype high production longitudinal sealing application vehicle and a large ; capacity transfer kettle trailer designed to efficiently resupply and support high production highway sealing operations. ; Defective commercial sealant melting equipment had rendered the TTLS equipment effectively unusable for general ; deployment. In addition to replacing deficient components, Caltrans requested inclusion of additional features to ; further enhance functionality. The most significant upgrade was to add in-lane sealing capabilities. An electrically ; heated sealant hose and application wand assembly was developed on the front of the application machine to support ; manual in-lane crack sealing capabilities. The rebuilt TTLS application vehicle was then renamed Sealzall to reflect ; the expanded sealing capabilities. The Sealzall machine retains the continuous 2-5 mph moving lane closure ; longitudinal sealing functionally first developed for the TTLS with the additional features of compressed air blast ; crack cleaning and hot sealant recirculation. The Sealzall will ultimately be turned over to Caltrans for full highway ; operational deployment.
