• Abstract:
  Riprap rundowns are often used by the New Mexico Department of Transportation (NMDOT) to
  
  capture and drain the runoff approaching or leaving bridge decks. Rundowns are generally located at
  
  the ends of a bridge deck to transport the water down the surface of the slopes of bridge embankments.
  
  They constitute an important part of the bridge drainage system. In some occasions, riprap rundowns
  
  have also been used for drainage and erosion protection of slopes and embankments along highways in
  
  New Mexico. The NMDOT Drainage Section identified recurrent failures of the riprap rundown
  
  structures throughout the state. The poor performance and failures of the riprap rundowns in some areas
  
  have required costly maintenance repairs and reconstruction. This study is aimed at identifying and
  
  characterizing the most frequent failure modes for riprap rundowns and providing best management
  
  practice (BMP) recommendations to improve the performance of these structures. Design, materials
  
  and construction issues were considered. Selected cases of rundowns that exhibited typical problems
  
  were described in this report to illustrate the failure modes and performance problems.
