A Technical Handbook on Bituminized Jute Paving Fabric (BJPF) A Partial Substitute and Reinforcement of Bitumen Mastic

The book states that in the last quarter of the twentieth century, a new class of materials called Geo-synthetics emerged which led to significant revolution in the design of geotechnical and geo-environmental systems. Geotextiles extend the service life of roads, increase their load carrying capacity and reduce rutting and other distresses. The effectiveness of geotextiles in stabilization and separation roles with flexible pavements has been extensively researched. Recognizing the vast potentiality of this developed Bituminized Jute Paving Fabric (BJPF) as overlay on existing pavements to reinforce and partially substitute the bitumen mastic, a strong desire of sharing the findings stimulated by the author to write this comprehensive technical handbook. The author firmly believes that this book will at least partially fulfill the requirements of the interested engineering students and practicing engineers and may prompt them to delve deeper into the subject to explore new avenues for its use and to refine the existing design methodologies.

Swapan Kumar Ghosh is the Professor and Head of the Department of Jute and Fibre Technology at the Institute of Jute Technology, University of Calcutta, India. He has been engaged in extensive research and developmental work related to the field of Geo-synthetics and Geotextile Technology since 1997 when Geotextiles both in man-made and natural fibers started proving effective in improving geotechnical characteristics of soil and found extensive uses for various technical end-uses like erosion control, management of slopes, strengthening of roads, stabilization of embankments, protection of river-banks, consolidation of soft soil, etc.
