There's an infamous stretch of highway that twists and turns through the rugged border mountains that separate Tennessee and North Carolina. Author: Isabel Lohman. North Carolina’s Strategic Highway Safety Plan is unique because it serves as a dynamic resource that will document the progress of North Carolina’s highway safety efforts.

The NCGS is mapping bedrock and collecting rock slope stability data along the North Carolina segment of the BRP as part of a geologic inventory of the BRP funded by the National Park Service.

The effect of water on cut and fill slope stability is briefly discussed below. • Importance of Water Next to gravity, water is the most important factor in slope stability. The effect of gravity is known, therefore, water is the key factor in.
On steep slopes, leveling involves a process called cut and fill whereby rock and soil are cut from higher slopes and used to fill in the land below. It is important to stabilize both the cut and the fill banks in order to control erosion/sedimentation and building site stability.

COURSE DESCRIPTION: This course covers important aspects associated with the design and construction of soil slopes and embankments.
It is intended to provide transportation earthwork professionals with knowledge to recognize potential problems with soil slope/embankment stability and deformation in transportation projects.
and Reinforced Soil Slopes Volume 1 & Volume 2” November Where the slope face is greater than 70 degrees, the design will be in accordance with criteria specified for retaining walls, see Section Rock Slope Design The rock cut design shall include stability analyses, an economical cut slope, ditch design for rockfall.
The Geotechnical Engineer shall design the cut slopes in accordance with the West Virginia Department of Transportation, Division of Highways Design Directive series. For large cut slopes, one or two benches may be eliminated based on the modeling discussed below.
Cut Slopes Determination of stable cut slopes. Retaining Walls Assessment of overall stability (global and compound). Deep/Shallow Foundations Assessment of overall stability for structures located on slopes.
Landslides Assessment of landslides, remediation methods, & back-analysis. Table Slope Stability Analysis – Geotechnical Problems. Q-slope is an empirical rock slope engineering method for assessing the stability of excavated rock slopes in the field.
Intended for use in reinforcement-free road or railway cuttings or in. The paper discusses the important contribution that engineering geology makes to the construction processes of excavation and the forming of foundations. The contribution to the construction of highways is described.
In particular, the influence of geology on cut slope stability, soft and hard ground excavation (including tunnelling), bearing capacity, settlement, subsidence and the choice of Cited by: 1. full range of riprap slopes. Overtopping flow on embankments with slopes less than or equal to (4H:1V) covers the riprap.
Forslopes greater thanthe overtopping flow must be contained within the layer of riprap for stability, although an insignificant amount of highly-aerated water splashes and cascades over the top of the riprap.
During the project design phase the subsurface investigation is completed and the cut slope design recommendations are prepared.
Included in the recommendations are the slope inclinations required for stability, mitigation requirements if needed and the usability of excavated cut material. These Standard Specifications for the Construction of Roads and Bridges on Federal Highway Projects are issued primarily for constructing roads andbridges on Federal Highway projects under the direct administration of the Federal Highway Administration.
These specifications are cited as "FP" indicating "Federal Project. The project should maintain a slope similar to normal conditions.
The slope, or grade, of the project must not be so steep that it endangers the public or interferes with public use of the beach. Nourishment projects may be subject to the North Carolina Environmental Policy Act (NCEPA), which requires a NCEPA review.

Exceptions have been made at the end bent slopes for the bridge over Doby Creek, where (H:V) slopes are being utilized, and at the end bents for the bridge over I, where MSE walls are being utilized.

North Carolina tree cutting law affecting residents Click on any image below to enlarge: North Carolina residents are starting to feel the impact of a law passed by that state’s legislature which allows billboard companies much greater leeway to cut down and remove trees and vegetation on the public right of way.
N Carolina No. 2 in Risky Dams Where Failure Could Kill North Carolina has one of the country's largest collections of poorly maintained dams that could put people people's lives at risk. This first try faltered, yet debate of it helped lead the legislature to include in the and budgets $, a year to continue North Carolina Geological Survey work.
This is a state project you could say is long overdue. It is to update North Carolina mountain topographical maps that cite geodetic vertical datum.

• overall slope stability • subsurface profile (soil, groundwater, rock). Use either the shovel or a scooper to dig your slope along the cleared pathway. The best way to create the slope is to mark the spot on the slope where you will want this stretch of path to end.
Running a string from the starting point at the top end of the pathway down to the ending point at the bottom end will help eye up your slope. A landslide is defined as the movement of a mass of rock, debris, or earth down a slope.
Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity. The term "landslide" encompasses five modes of slope movement: falls, topples, slides, spreads, and flows.
These are further subdivided by the type of. Months of I construction starts at the North Carolina-Tennessee line. It's going to be a mess. But here are the safety improvements that are happening on the notorious stretch of highway. Road Standards and Paving Standards ASTM's road and paving standards provide the specifications and test methods pertinent to the material, physical, mechanical, performance, and application requirements of road surfaces and pavements.

Laws are made to protect everyone. The leading cause of traffic fatalities in North Carolina is speeding. Motorists should plan ahead to allow enough time to arrive safely at his or her destination.
Remember, it is easy to speed. It takes restraint not to exceed the posted speed limit.Riprap used for surface stabilization of slopes does not add significant resistance to sliding or slope failure and should not be considered a retaining wall. Slopes approaching may require special stability analysis.
The inherent stability of the soil must be File Size: KB.The project involved the upgrade of an meter section from a two- to four-lane rural arterial highway standard. To avoid very high rock cuts, the two additional travel lanes were constructed over steep bedrock and rock -ill slopes, located downslope of the highway.
