Download or read book Precision Estimates of AASHTO T283 written by Haleh Azari and published by . This book was released on 2010 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents an interlaboratory study (ILS) resulting in a precision and bias statement for AASHTO T283, "Resistance of Compacted Hot Mix Asphalt (HMA) to Moisture-Induced Damage." To gain insight into the variability of the T283 test results, a micro-scale finite element analysis using X-ray images of the test specimens was conducted. The ILS included preparing and testing 6 replicate specimens according to AASHTO T283 using two different aggregate sources and two compaction methods. A sandstone aggregate representing moisture susceptible and a limestone aggregate representing moisture resistance were selected for the study. Marshall and Superpave gyratory compactors were selected as means of compaction to create test specimens with different structures.

Book excerpt: This report presents the results of an interlaboratory study (ILS) to prepare precision estimates for AASHTO T265 test method used for Laboratory Determination of Moisture Content of Soils. The materials for the ILS included two coarse- and two fine-grained soil-aggregate blends that were prepared according to Grading A and Grading E of AASHTO M147, "Materials for Aggregate and Soil-Aggregate Subbase, Base, and Surface Courses." Each of the four blends had less than 10% soil passing #200 sieve to represent suitable materials for base and subbase.

Book excerpt: This report presents the results of an interlaboratory study (ILS) to prepare precision estimates for the AASHTO T267 test method used for the determination of organic content in soils by loss of ignition. The materials for the ILS included sand, silt, and clay each blended with 2%, 5%, and 8% finely ground walnut shells as the organic material. A total of 27 laboratories provided results of percent organic content of three replicates of each soil-organic blend.
Download or read book Materials for Civil and Construction Engineers Pearson New International Edition written by Michael S. Mamlouk and published by Pearson Higher Ed. This book was released on 2013-08-27 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: For courses in Civil Engineering Materials, Construction Materials, and Construction Methods and Materials offered in Civil, Environmental, or Construction engineering departments. This introduction gives students a basic understanding of the material selection process and the behavior of materials — a fundamental requirement for all civil and construction engineers performing design, construction, and maintenance. The authors cover the various materials used by civil and construction engineers in one useful reference, limiting the vast amount of information available to the introductory level, concentrating on current practices, and extracting information that is relevant to the general education of civil and construction engineers. A large number of experiments, figures, sample problems, test methods, and homework problems gives students opportunity for practice and review.
