Soil moisture proficiency sample program / by Steele, Garland W.(CARDINAL)768876; Strategic Highway Research Program (U.S.)(CARDINAL)298325;
Includes bibliographical references (page 133).Abstract -- Summary of research -- Appendix I: Descriptive test results on materials used by AMRL for samples -- Appendix II: AMRL report on SHRP Moisture Content Proficiency Sample Program -- Appendix III: Correspondence regarding transmitting AMRL report -- Appendix IV: Correspondence concerning analysis of data -- Appendix V: Memorandum on variance component analysis -- Appendix VI: Example of report distributed to each participant -- Appendix VII: AASHTO/ASTM format precision statements.This report describes the development of the Long-Term Pavement Performance (LTPP) soil sample selection process based on the American Association of State Highway Transportation Officials model. Laboratory results present the bias in determining moisture content in cohesive soil and base course aggregate samples.

Determining soil volumetric moisture content using time domain reflectometry / by Klemunes, John A.(CARDINAL)320539; United States.Federal Highway Administration.Office of Engineering Research and Development.; Turner-Fairbank Highway Research Center.(CARDINAL)286897;
Includes bibliographical references (pages 65-68).Introduction -- Literature review -- Laboratory procedure -- Phase I study -- Phase II study -- Conclusions -- Recommendations -- References.Final report;Time domain reflectometry (TDR) is a technique used to measure indirectly the in situ volumetric moisture content of soil. The purpose of this study is to enhance the predictive accuracy of in situ volumetric moisture content estimation from TDR measurements. The study is divided into two phases. The initial phase evaluates the five known methods of analyzing the apparent length of TDR responses to determine which provides the most accurate method for estimating the volumetric moisture content. Phase II, through a mixing model form, regresses the volumetric properties of the soil and the apparent length of the TDR response to obtain a predicted volumetric moisture content.Performed and sponsored by Office of Engineering R & D, Federal Highway Administration.
