DESCRIPTION:
The basic concept behind ground improvement technologies is to improve
or modify poor and marginal in-situ soil and rock conditions to meet project
foundation requirements. One or more ground improvement methods on
a project can: increase bearing capacity, control vertical and lateral
deformations, decrease imposed loads, improve lateral stability, increase
resistance to liquification, form a seepage cutoff and fill subsurface
voids. Implementation of these methods has enabled the successful
construction of the following highway features: fill and cut earthworks,
tunnels, culverts, retaining walls and structural foundations. The
versatility of these methods makes them attractive to both new construction
and rehabilitation of existing features. These methods have been
successfully used on many sites with great success but are genenrally not
fully integrated into transportation practice because of a technical knowledge
gap outside of the specialty contracting community. The objective
of DP116 is to mainstream these versatile tools into routine practice in
safe and cost-effective applications by providing a fundamental technical
understanding.
The primary objective of Demonstration Project 116 is to enhance the acceptance and implementation of ground improvement methods by the transportation community. Ground improvement technologies are geotechnical construction methods used to modify and improve poor and marginal soil and rock conditions to meet project requirements. The ground improvement methods addressed in this project include: Grouting, Vertical Wick Drains, Soil Mixing, Stone Columns, Lightweight Fill Materials, Vibrocompaction, Dynamic Compaction, Soil Nailing, Mechanically Stabilized Earth Walls, Reinforced Soil Slopes and Micropiles.
TARGET AUDIENCE:
This Demonstration Project is intended for design generalists (project
planners, roadway designers, consultant reviewers), design specialists
(geotechnical, structural), construction engineers, and specification and
contracting specialists involved with projects having problematic site
conditions.
