Abstract:The use of micropiles has grown significantly since their conception in the 195Os, and in particular since the mid-1980s. Micropiles have been used mainly as elements for foundation support to resist static and seismic loading conditions and less frequently as in-situ reinforcements for slope and excavation stability. Many of these applications are suitable for transportation structures. Implementation of micropile technology on U.S. transportation projects has been hindered by lack of practical design and construction guidelines. In response to this need, the FHWA sponsored the development of this Micropile Design and Construction Guidelines Implementation Manual. Funding and development of the manual has been a cooperative effort between FHWA, several U.S. micropile specialty contractors, and several State DOT’s This manual is intended as a “practitioner-oriented” document containing sufficient information on micropile design, construction specifications, inspection and testing procedures, cost data, and contracting methods to facilitate and speed the implementation and cost effective use of micropiles on United States transportation projects.
