The accumulation of waste tires is a global resource and environmental problem. The landfill or incineration of tires will infiltrate toxic chemicals into the surrounding environment, which poses a serious ecological threat to the environment. A large number of studies have shown that waste tires can be used in geotechnical engineering, which provides a good idea for the recycling of waste tires. Up to now, researchers have tested the performance of soil mixed with waste tires by dynamic triaxial test, California load ratio test, unconfined compression test, direct shear test, consolidation test, and expansive force test. Rubber can improve the mechanical properties and deformation properties of sand.

Newell, Darren, and Erwin Oh. The use of fiber reinforced polymer FRP materials in civil engineering structures is relatively new. FRP reinforcing bars are starting to be used in lieu of conventional steel reinforcing bars where improved corrosion resistance is required in soil nailed reinforced earth retaining structures. Presently, there is only a relatively small body of knowledge on numerical modeling techniques and the response of FRP reinforcing nails under load. This paper provides an overview of research completed to date on both steel and FRP reinforced soil nails, and an outline of planned future research. Traditionally, soil nail earth retaining structures use steel reinforcing bars.

This one-of-a-kind reference evaluates the efficacy, stability, and strength of various soil walls, slopes, and structures enhanced by geosynthetic.

Geosynthetic-reinforced retaining GRR walls have been increasingly used to support roadways and bridge abutments in highway projects. In recent years, advances have been made in construction and design of GRR walls for highway applications. For example, piles have been installed inside GRR walls to support bridge abutments and sound barrier walls. Geosynthetic layers at closer spacing are used in GRR walls to form a composite mass to support an integrated bridge system.

Novel approaches to the dynamic analysis of the reinforced soil walls have been reported in the literature. Use of marginal soils reduces the cost of geosynthetic reinforced soil walls if proper drainage measures are taken. Therefore the affect of using cohesive marginal soils as backfill in geosynthetic reinforced retaining structures were investigated in this research.

Polypropylene fiber is a common soil reinforcement material which is used to reinforce a common clay in northeast China. Numerical analysis method was performed to investigate the effect of polypropylene fibers on stability of embankment slope subjected to freeze-thaw cycles. The orthogonal experiments of three factors freeze-thaw cycle, fiber content, and fiber length and three levels were carried out, and the corresponding nine groups of specimens were made, whose shear strength parameters internal friction angle and bond force were measured by direct shear test. Then, the experimental results were analyzed by analysis of variance and range analysis so that the optimum fiber content and fiber length can be determined.

Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. An important objective of this study is to unequivocally define the boundaries for such behavior. The focus of this review was to summarize pertinent information published in technical venues that was deemed relevant to assess 1 the different components of the research and 2 the composite behavior of GRS structures.
