- The application of small nuclear magnetic resonance spectrometers to quality control measurements of asphalt and asphalt-aggregate mixes / by Pearson, Robert M.; Strategic Highway Research Program (U.S.)(CARDINAL)298325; Tri-Valley Research (Pleasanton, Calif.);
Includes bibliographical references (page 42).Introduction -- Instrumentation -- Experiments -- Conclusions and suggestions for further work -- References.Classic wide-line nuclear magnetic resonance (NMR) techniques are used to measure the quantitative amounts of asphalt in asphalt-aggregate mixtures, including full four-inch highway cores. This report illustrates how wide-line NMR can be used to measure and study the physical properties of both neat asphalts and asphalt in mixtures. A correlation relating known physical property measurements to NMR parameters is given for a wide range of neat asphalts. Also discussed is how interactions between the asphalt and the aggregate in a mixture influence the physical properties of the asphalt and determine the physical properties of the mix.Performed under contract

- Long-term pavement performance information management system : five year report / by Hadley, William O.; Copeland, Charlie R.(Charlie Reagan)(CARDINAL)323078; Strategic Highway Research Program (U.S.)(CARDINAL)298325;
Includes bibliographical references (pages 72-75).SHRP-LTPP Information Management System (IMS) -- Data/information sources -- Data types and elements and sources of the data -- Equipment and operations -- References.This report describes the information management system within SHRP-LTPP to service the NPPDB and the quality assurance checks that verify the presence, reasonableness, accuracy, and validity of the data prior to incorporation into the NPPDB. The National Pavement Performance Database (NPPDB) houses many types of data including inventory, materials characterization, longitudinal profile, deflection, cross profile, distress, friction, maintenance, rehabilitation, climate, and traffic. The report discusses data types and elements in detail and notes data sources. Equipment and operations of the NPPDB are described, as well as NPPDB products.Performed under contract no.

- Development and validation of performance prediction models and specifications for asphalt binders and paving mixes / by Lytton, Robert L.(CARDINAL)325431; Strategic Highway Research Program (U.S.)(CARDINAL)298325;
Includes bibliographical references (pages R.1-R.8).Introduction -- Material property relationships: Constitutive equations -- Pavement performance models and relationships -- Field experiments for the general pavement studies (GPS) sites -- Laboratory testing of asphalt concrete mixtures -- Summary of material properties -- Pavement performance models: Predictions and calibration -- Validation -- Conclusions and recommendations -- References.A result of the Strategic Highway Research Program's asphalt research is the development of performance-based specifications for asphalt binders and mixtures to control 3 distress modes: rutting; fatigue cracking; and thermal cracking. The SHRP A-005 project developed detailed pavement performance models to support these binder and mixture specifications and performance-based mixture designs. This report documents the findings of this extensive research effort and provides supporting data for the performance-based specifications and mixture design procedure called SUPERPAVE. The A-005 contract developed and used a sophisticated, mechanistic-based pavement performance model to define the relationships between asphalt binder and mixture properties and pavement distress. A comprehensive pavement performance model was developed that predicts the amount of fatigue cracking, thermal cracking and rutting in asphalt concrete pavements with time, using results from the accelerated laboratory tests. The pavement performance models for each distress were also used to confirm the relevant binder and mixture properties established by other SHRP contractors. The model has 3 parts: a mixture evaluation model; a pavement response model; and a pavement distress model.Performed under contract no.

- Stiffness of asphalt-aggregate mixes / by Tayebali, Akhtarhusein A.(Akhtarhusein Asgarali)(CARDINAL)272065; Monismith, Carl L.(CARDINAL)166170; Tsai, Bor-wen.; Strategic Highway Research Program (U.S.)(CARDINAL)298325; University of California, Berkeley.Institute of Transportation Studies.(CARDINAL)137668;
Includes bibliographical references (page 47).Introduction -- 2 x 2 pilot test program -- 8 x 2 expanded test program -- Summary -- References -- Appendices.This report presents an evaluation of several test systems for stiffness determination of asphalt-aggregate mixes, including 1) axial resilient stiffness, 2) diametral resilient stiffness, 3) resilient and dynamic flexural stiffness, and 4) dynamic shear stiffness. All of the stiffness test systems were found to be sensitive to mix and test variables, especially to asphalt source, asphalt content, aggregate type, and air-void content. Models are presented to permit estimation of flexural stiffness (and loss-stiffness) from shear stiffness (and loss-stiffness in shear) at 20 deg C and 10 Hz frequency.Performed under contract

Introduction -- Selecting mixture materials -- Level 1 mix design (low traffic levels--volumetric design) -- Level 2 mix design (intermediate traffic levels) -- Level 3 mix design (high traffic levels) -- Superpave mix design: An example -- Appendices.This laboratory manual presents Superpave mix design system in a complete, step-by-step format. It is intended for engineers and technicians in public and private organizations to use when designing paving mixes for all classes of highways, from farm-to-market roads to urban freeways. An essential companion to this manual is "The Superpave Mix Design System Manual of Specifications, Test Methods and Practices." The Superpave software program--"The Superpave Specification, Mix Design and Support Program"--And its users manual are also necessary to take full advantage of the mix design system.Performed under contract no.

- Resistance of concrete to freezing and thawing / by Janssen, Donald J.(Donald James),1956-(CARDINAL)286902; Snyder, Mark B.(Mark Bennett),1957-(CARDINAL)324806; Strategic Highway Research Program (U.S.)(CARDINAL)298325;
Includes bibliographical references (page vii).Part I: Frost resistance of concrete made with durable aggregate -- Introduction -- Laboratory testing program -- Innovative test procedures -- Results -- Acceptable variability and maximum expected errors in results -- Frost-resistance model -- Summary and recommendations for part I -- References -- Appendices -- Part II: Frost resistance of concrete made with frost-susceptible aggregate -- Introduction -- Background -- Current identification procedures -- Washington hydraulic fracture test -- Mitigation of existing D-cracking -- References -- Appendices -- Part III: Field testing program -- Introduction -- Paste test program -- D-Crack mitigation test program -- Other field mixes -- Conclusions and summary -- Appendices.This study, aimed at improving the freeze-thaw resistance of concrete, consists of three parts. Part I evaluates parameters affecting the freeze-thaw durability of concrete. A modification of the existing standard of method for determining the durability factor of concrete specimens is proposed, and a new procedure for fundamental transverse frequency (used in durability factor calculations) has been developed. Part II focuses on developing better methods for identifying nondurable aggregates, and has resulted in a rapid new test based on the hydraulic fracture of aggregates. Part III describes field experiments to evaluate the freeze-thaw resistance of a number of specified concrete mixes and the use of sealants to mitigate D-cracking. Preliminary field performance results are presented.Performed under contract no.
