• 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.
