Stabilization of unpaved roads 1. INTRODUCTION. Low volume roads carry low volumes of traffic which can be anything from a bicycle to afully loaded road train and these roads tend to be not well funded in comparison with themajor roads.The Northern Territory's road ne... DF Norris,TI ...
Sediment pollution from unpaved roads is a well-documented problem across the United States and the world. The quality of road surface material is a large determining factor in how much sediment is generated from the road surface during rain events. This study attempted to quantify the sediment ...

It is concluded that the methodology developed enables reconstruction of road defect geometries with an accuracy sufficient to allow specific types and dimensions of defects to be recognized for the purpose of road maintenance. By extending the methodology to public unpaved roads, maintenance could be ...
