Download or read book Using Ignition Ovens to Determine Asphalt Content and to Prepare Aggregates for Sieve Analysis written by Robert E. Lee and published by . This book was released on 1996 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Materials and Tests Division's Bituminous Section evaluated the ignition method as an alternative to the solvent method for determining asphalt content. Three ovens (the Gilson Asphalt Binder Ignition Furnace, Model HM 378; the NCAT Asphalt Content Tester; and the Troxler Asphalt Quality Analyzer) were evaluated for accuracy, precision, and performance. Ignition was proven to be an appropriate method of determining asphalt content. The test procedure resulting from this work is Tex-236-F, which is included in Appendix A.

Download or read book Determining the Degree of Aggregate Degradation After Using the NCAT Asphalt Content Tester written by Randolph Reyes and published by . This book was released on 1997 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the research conducted was to determine if aggregate degradation takes place and to measure the possible degree of degradation after bituminous mixtures are heated inside the NCAT Asphalt Content Tester. A study was conducted which compared the original aggregate blend (control specimens) to the residual aggregate blend (experimental specimens) obtained after several bituminous mixtures were heated inside the NCAT Asphalt Content Tester. The control specimens and the experimental specimens used to produce the bituminous mixtures were the result of an aggregate sample which was split three times. Two methods of analysis were used to review the gradation results.

Available in PDF, EPUB and Kindle. Book excerpt: "Determining the Asphalt Binder Content of Hot Mix Asphalt (HMA) by the Ignition Method," requires determination of asphalt and aggregate correction factors for asphalt mix designs for each ignition furnace used to test a design. In some cases, where there are numerous asphalt mix designs or numerous ignition furnaces testing a particular mix design, correction factors may be shared between ignition furnaces, though this practice is not strictly permitted by AASHTO T 308 without supporting evidence. The objectives of this research were to (1) determine the significant influences that affect the variability of asphalt and aggregate correction factors for ignition furnaces; (2) develop guidelines for the installation, operation, and maintenance of ignition furnaces to minimize the variability in correction factors between furnaces; and (3) develop and document a statistically valid correction factor verification procedure to identify and troubleshoot causes for non-comparing, statistically different, or biased results of AASHTO T 308. The research was conducted in three parts: (1) a study of the sensitivity of asphalt and aggregate correction factors to variation in experimental factors such as furnace type, test temperature, asphalt content, and sample mass; (2) a round-robin study to identify correction factor outliers and determine the contributory cause(s); and (3) troubleshooting of outliers from the round-robin study. The research found that the primary factors affecting asphalt and aggregate correction factors determined by AASHTO T 308 are furnace type and test temperature. Conducting the test at 800°F appears to substantially reduce the magnitude and standard deviation of the correction factors for asphalt mixtures that do not contain lime. Sharing correction factors among different ignition furnaces appears acceptable for low correction factor aggregates (0.1% or less) but is problematic for aggregates with correction factors of 1.0% or greater. The current precision estimates in AASHTO T 308 appear applicable only to mixtures with low correction factor aggregates. The key product of this research is a Proposed Standard Practice for Installation, Operation, and Maintenance of Ignition Furnaces (Appendix I). Development of a verification procedure to identify causes for non-comparing, statistically different, or biased test results from ignition furnaces was found to be premature and further research is planned.

This book was released on 1996 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is much concern over chlorinated solvents currently used for asphalt content extraction testing. This research was undertaken to investigate alternative methods that do not use chlorinated solvents for asphalt cement (AC) content determination. Methods considered include nuclear asphalt content gauges, extraction with biodegradable solvents, ignition oven, and recordation. Information was gathered from the literature, from a survey of all state highway agencies, and from interviews with selected agencies. The advantages and disadvantages of each of the alternative methods were identified and are presented in the report.

Available in PDF, EPUB and Kindle. Book excerpt: This report develops procedures and associated criteria for laboratory conditioning of asphalt mixtures to simulate short-term aging. The report presents proposed changes to the American Association of State Highway and Transportation Officials (AASHTO) R 30, Mixture Conditioning of Hot-Mix Asphalt (HMA), and a proposed AASHTO practice for conducting plant aging studies. The report will be of immediate interest to materials engineers in state highway agencies and the construction industry with responsibility for design and production of hot and warm mix asphalt.
