Kentucky Erosion Prevention and Sediment Control Field Guide PDF  
This Field Guide will take you through the erosion and sediment control process. It starts out with sections on pre-project planning and operational activities. The rest of the guide discusses erosion prevention and sediment control by starting at the top of the hill, above the project site, and proceeding down the slope through the bare soil area, ditches and channels, traps and basins, and on down to the waterways below.

Hollow Bar Soil Nails: Pullout Test Program PDF 
The use of Hollow Bar Soil Nails (HBSNs) is growing in the excavation support and retaining wall construction. It is anticipated that the use of the HBSN technology could reduce construction schedules, costs, and environmental impacts. The current state of practice for design bond strengths and load testing procedures is based on the current soil nail practice but varies depending on the installation contractor and product recommendations. The objective of this study was two-fold. The first objective was to develop an initial data file from installation and testing at four sites of the available grout-to-ground bond stress of HBSNs, and to determine if correlations exist with traditional solid bar, drill, and grout soil nails (for example, the published nominal values in FHWA-IF-03-017 [GEC No. 7]). The second objective was to establish recommendations for practical, standard ways of performing pullout tests on HBSNs. CFLHD.

Hollow Bar Soil Nails: Review of Corrosion Factors and Mitigation Practice PDF
Hollow bar soil nails (HBSNs) have been used in the United States in earth retention systems for over 10 years. HBSNs are commonly used in place of solid bar soil nails (SBSNs) when the solid bar installation would require temporary casing of the hole. A state-of-the-practice document was prepared by FHWA in 2006 to identify (a) the various peculiarities of HBSNs in comparison with conventional SBSNs, and (b) areas of further research, evaluation and testing that would help agency personnel and design professionals understand the potential of HBSNs as a mainstream technology for permanent soil nail applications. This report concentrates on one of the specific areas of study identified in the 2006 report as related to development of corrosion mitigation guidance. CFLHD.

Soil Nail Analysis Program: User’s Manual PDF
Soil nail walls are internally stabilized earth-retaining structures. Soil nail walls use a top-down construction with in situ reinforcement to support temporary or permanent excavations. In certain conditions, soil nailing is a viable alternative to other ground anchor systems, considering technical feasibility, cost, and construction duration. This user’s manual discusses the theoretical basis for the computer program, gives a comparison of available soil nail wall design guidelines, discusses program execution including inputs and outputs, and includes two worked examples to demonstrate use of the program.
