Full scale test roads combined with a theoretical analysis were
used to evaluate the benefits of incorporating a fabric as a base course
support material for gravel paved roads.
One material, a synthetic, nonwoven, polypropylene fabric was
used in this investigation. This fabric was used on top of the subgrade...
This thesis presents a procedure to identify and evaluate forest
arterial and collector networks. The procedure identifies those
decision criteria important in evaluating both the arterial and
collector networks and the specific facilities identified on these
networks. The procedure incorporates the decision criteria and results
from network and facility analysis...
An evaluation of fabric reinforcement of the roadway
structure is made. The study includes a parametric analy
sis using layered elastic theory and a series of large
scale model tests.
The parametric. study analyzes the stresses and
strains of roadway structures with a fabric layer between
tna surface layer and...
The development of a pavement management system for low-volume roads is a difficult task. There are many interrelated activities that must be considered, such as planning, design, construction, maintenance, and pavement evaluation. This paper addresses the evaluation and maintenance components of a pavement management system for low-volume roadways and provides...
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...
This thesis presents an economic analysis for a proposed toll
road which is to separate different types of traffic such as pedestrians,
slow speed vehicles and high speed motor vehicles, and to
divert through traffic from the local roads. The use of a toll road
usually provides significant savings in...
The effects of roadbuilding, logging and burning upon stream
runoff responses to individual storms are evaluated for the Alsea
experimental watersheds, located in the Oregon Coast Range, The
parameters analyzed are peak discharge, induced peak discharge,
time-to-peak, and storm-runoff volume. The volume parameter is
further sub-divided into total, quick, delayed,...
