The book presents a comprehensive experimental and analytical study on the use of waste plastic, particularly PET bottle strips, as randomly distributed fiber reinforcement (RDFS or ply soil) for improving the engineering properties of clayey soils. It integrates geotechnical engineering principles with environmental sustainability by addressing the growing challenge of plastic waste disposal through its beneficial reuse in ground improvement applications.
The study begins by highlighting the environmental problem of increasing plastic waste, especially low-density polyethylene (LDPE) and polyethylene terephthalate (PET) products, which occupy a significant volume of landfills while having limited recycling potential. The book argues that instead of treating waste plastic as a disposal burden, it can be effectively utilized as a soil reinforcement material, thereby solving two problems simultaneously: waste management and poor soil performance
Theoretical background is provided on soil stabilization and soil reinforcement techniques, categorizing them into soil stabilization using binders, reinforcement with continuous planar members, and reinforcement with randomly mixed fibers (ply soil). Special emphasis is placed on RDFS, which differs from conventional reinforced soil systems by maintaining isotropy in strength due to random fiber orientation. Historical and contemporary examples, including natural fiber reinforcement and plant root analogies, are discussed to establish the conceptual basis of fiber-reinforced soils
An extensive literature review forms a major portion of the book, covering several decades of experimental and theoretical research on fiber-reinforced soils. Studies involving synthetic, natural, and waste plastic fibers are critically reviewed, focusing on parameters such as fiber content, aspect ratio, orientation, confining pressure, and soil type. The review consistently demonstrates that fiber inclusion improves shear strength, ductility, residual strength, bearing capacity, and energy absorption, while reducing brittleness and post-peak strength loss. The concept of critical confining stress, beyond which fibers become effective in reinforcing soil, is also discussed in detail
The motivation and objectives of the present study are clearly defined: to investigate the improvement in strength and deformation characteristics of clayey soil mixed with waste PET bottle strips and to evaluate the tensile properties of the plastic strips themselves. The scope includes laboratory testing on pure clayey soil and clay amended with 10% and 20% sand, reinforced with varying percentages (0.5%–2%) and aspect ratios of PET strips
The book elaborates on the materials used, detailing soil characterization as per IS codes and preparation of PET bottle strips of controlled dimensions. A well-structured test program is described, including Atterberg limits, grain size distribution, Proctor compaction, unconfined compressive strength tests, and unconsolidated undrained triaxial tests. Testing procedures are explained systematically, ensuring reproducibility and technical rigor
In the results and discussion, the study demonstrates that the inclusion of PET bottle strips significantly affects soil behavior. Maximum dry density generally increases and optimum moisture content decreases with fiber inclusion up to an optimum fiber content of about 1%. Unconfined compressive strength and undrained shear strength show notable improvement up to this optimum level, beyond which strength decreases due to fiber interference and poor stress transfer. The angle of internal friction improves with fiber addition and increased sand content. Aspect ratio plays a critical role, with moderate ratios proving more effective than higher ones
The book concludes that waste PET bottle strips are an effective, economical, and eco-friendly reinforcement material for improving weak clayey soils. An optimum fiber content of around 1% is identified for maximum benefit. The study reinforces the potential of plastic waste reuse in geotechnical engineering, contributing both to sustainable construction practices and environmental protection
Overall, the book successfully combines environmental engineering, geotechnical experimentation, and practical design insights, making it a valuable reference for researchers, students, and practicing engineers interested in sustainable ground improvement techniques.
