Chemical and Vegetative Stabilization of Soils:Laboratory and Field Investigations of New Materials and Methods for Soil Stabilization and Erosion Control,

摘要

A study was conducted on various chemical and vegetative methods of soil stabilization for possible use in the USBR's construction and O&M programs. This report summarizes three main items of work accomplished under the study: (1) Section A. Laboratory Studies. - (a) Results of screening tests conducted on 30liquid soil stabilizing materials. Based on the results of these tests,tentative performance requirements were developed for water-based soil stabilizers. (b) Special studies conducted on materials and methods to waterproof problem soils,to arrest erosion occurring on slopes,and to bind gravel together for riprap applications. (2) Section B. Field Applications. -Discussions on where various chemical and vegetative methods have been used in new construction,rehabilitation,or O&M work. (3) Section C. State-of-the-Art Survey. - A survey on chemical stabilization of soils,and revegetation methods and materials for erosion control. Results of this study indicate that through chemical and vegetative stabilization of disturbed soils,sediment production can be reduced,fertile top soil preserved,and a more environmentally acceptable condition achieved after construction is completed.
