Geometric design standards have not been developed specifically for low volume roads. Design standards and criteria are extrapolated from higher standard roadways that are often not relevant to low volume roads. Safety is a primary criterion used for selection of design standards along with economic, financial, social and environment factors....
Logging road construction in the coastal regions of British Columbia has always been a difficult and expensive undertaking. The soils are generally ill-suited to road construction, rock outcrops are numerous, and climatic conditions unfavourable. In
addition, the mineral soils are overlaid by a heavy layer of partly decomposed organic material....
This study presents a rational process with supporting data to establish
appropriate road design controls, criteria, and standards for low volume
recreation and resource development. Much of the information presented can
be used to supplement design data presented in a National road design policy
published by the American Association of...
The purpose of this study was to provide the USDA-Forest Service,
Bureau of Land Management (BLM), and other agencies or industries
that may deal with temporary and intermittent use roads with
the necessary background information for the identification, economic
evaluation, and selection of the alternate surfacing systems and to
determine...
A post-failure investigation of a highway embankment constructed
over organic and sensitive subsoils was made with a series
of field vane tests. The results indicated that the embankment was
quite stable, and, therefore, the reliabilities of both the Φ = 0 slip-circle analysis and the field vane results seemed to...
Provides detailed information for the non-engineer on how to locate, design, and construct a road. Topics include identifying desirable and undesirable land features, constructing crowned, inslope, outslope, full-bench, and balanced roads, meeting road width, alignment, grade, excavation, drainage, and other structural requirements, laying out curves, and directing construction. Includes 25...
