Book Description
The objectives of this investigation were to determine the effect of pulverization on the strength, durability and swell characteristics of a lime stabilized clay soil. Samples were prepared with three different gradations which represented the pulverization of the soil. Maximum clay lump sizes of 3/4", 1/2" and passing #4 sieve were used for the three gradations. Samples were prepared with lime contents of 4% and 8% of the dry soil weight. The clay soil was classified as A-7-6 (20) in the AASHO soil classification system. All samples were compacted using a kneading compactor at the moisture content producing the maximum stabilometer R value. The samples were cured in air tight containers at 105° F ± 3° F for ten days and then cured for an additional four days at 105° F ± 3 °F at a relative humidity of 100%. At the end of the curing period the unconfined compressive strength, swell pressure and stabilometer R value of the samples were determined. Stabilometer R values were also determined for samples after 24 hours soaking and after one and three cycles of freezing and thawing. Results showed that pulverization significantly affected the strength, durability and swell characteristics of the samples. The stabilometer R value of samples containing well pulverized soil was significantly higher than the R value of samples containing larger unpulverized clay lumps. The unconfined compressive strength was similarly affected. The durability of the samples containing well pulverized material was much higher when determined following 24 hours of soaking or following either one or three cycles of freezing and thawing. Swell pressures of samples containing larger clay lumps were many times greater than the pressures exerted by the well pulverized samples. The higher lime content caused substantial improvement in the properties of the samples.

Book Description
This report contains 27 papers that serve as a testament to the state-of-the-art of civil engineering at the outset of the 21st century, as well as to commemorate the ASCE's Sesquicentennial. Written by the leading practitioners, educators, and researchers of civil engineering, each of these peer-reviewed papers explores a particular aspect of civil engineering knowledge and practice. Each paper explores the development of a particular civil engineering specialty, including milestones and future barriers, constraints, and opportunities. The papers celebrate the history, heritage, and accomplishments of the profession in all facets of practice, including construction facilities, special structures, engineering mechanics, surveying and mapping, irrigation and water quality, forensics, computing, materials, geotechnical engineering, hydraulic engineering, and transportation engineering. While each paper is unique, collectively they provide a snapshot of the profession while offering thoughtful predictions of likely developments in the years to come. Together the papers illuminate the mounting complexity facing civil engineering stemming from rapid growth in scientific knowledge, technological development, and human populations, especially in the last 50 years. An overarching theme is the need for systems-level approaches and consideration from undergraduate education through advanced engineering materials, processes, technologies, and design methods and tools. These papers speak to the need for civil engineers of all specialties to recognize and embrace the growing interconnectedness of the global infrastructure, economy, society, and the need to work for more sustainable, life-cycle-oriented solutions. While embracing the past and the present, the papers collected here clearly have an eye on the future needs of ASCE and the civil engineering profession.
