Paper, 2002Description: 11 sSubject(s): Bibl.nr: VTI 2002.0071Location: Abstract: The introduction of fixed anti-icing systems has raised issues regarding these systems relationship to other winter maintenance activities. These systems automatically dispense a deicing agent on a targeted surface by means of specially designed anti-icing spray nozzles. These systems permit the immediate treatment of a targeted surface in either an anti-icing or deicing mode. These systems have proven to be advantageous in addressing microclimates where black ice and frost are common or at remote or congested sites were logistical problems with trucks are encountered. These anti-icing systems find further application in areas with high winter accident rates and on structures where non-corrosive deicing agents are desired. A variety of anti-icing nozzles are available to accommodate specific structures. One of the popular anti-icing nozzle designs is the flush deck nozzle. These nozzles are positioned in the roadway such that the top surface of the nozzle assembly lies flush with the wear course. This placement is required so the nozzles may be placed anywhere on the road without becoming damaged by snow plowing operations, tires or other surface hazards. However, because of the nozzle's positioning, particles that are encountered on a roadway, such as abrasives, can settle into the nozzle openings. This paper reports on the effectiveness of the nozzle's particle rejection of common abrasives.Current library | Call number | Status | Date due | Barcode | |
