Download or read book Laboratory Evaluation of Typical ADOT Asphalt Concrete written by Michael S. Mamlouk and published by . This book was released on 1990 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: A typical Arizona Department of Transportation (ADOT) asphalt concrete mixture was evaluated based on the Asphalt-Aggregate Mixture Analysis System (AAMAS) procedure (NCHRP Project 9-6(1)). Two sets of ADOT asphalt concrete specimens were prepared using the California kneading compactor and the Marshall hammer. All tests recommended by the AAMAS project were performed. The test results were analyzed using the AAMAS guidelines. It was found that the diametral resilient moduli of the ADOT mixture are within the acceptable range. A typical AASHTO structural layer coefficient is recommended. The rutting potential is low in some cases and moderate in other cases. Recommendations for the evaluation of fatigue cracking and thermal cracking are provided. The potential for moisture damage is high, while the potential for disintegration is marginal.

This book was released on 2007 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: A research project was conducted to identify and document current modifications to ARIZONA 815c (75-blow Marshall method) used to develop gap-graded asphalt rubber asphalt concrete (GG AR AC) mix designs, and to develop and test improvements to provide a standard mix design method for use by contractors and consultants. Based on field performance data provided by the Arizona Department of Transportation (ADOT), the existing mix design method was successful and should serve as the standard for comparison of proposed improvements. Best practices were synthesized to develop proposed improvements. Three aggregate sources and two asphalt rubber (AR) binders were used for initial testing of the existing (control) mix design method and of the proposed changes. Rebound of compacted AR AC specimens was evaluated, as were Rice test results at 6% and 7% AR binder by weight of mix. The composition of the AR binders (rubber gradation and content) had more effect on the results than which mix design method was used. Additional replicate testing was performed by MACTEC and ADOT to confirm these findings. Changes to the AR AC mix design method consist primarily of making and curing Rice specimens in the same manner as Marshall specimens, tighter temperature ranges for mixing and compaction, incorporating Asphalt Institute calculations in a "User's Guide," and improving presentation. An ADOT construction project was used as an "acid test" to pilot the proposed mix design method and provide materials for a four-laboratory round robin to evaluate the precision of testing AR AC materials. The precision of round robin testing appears very similar to that of conventional asphalt concrete mixtures based on data from Proficiency Sample Programs of the AASHTO Materials Reference Laboratory and ADOT. The results indicate that the mix design method developed can be used by qualified laboratories to provide suitable AR AC mix designs

This book was released on 2010 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the study was to determine the effects of variability in key mix design factors, such as asphalt content, gradation, and density, on the laboratory performance of different hot-mix asphalt samples that were mixed and compacted in the laboratory. Variability was kept within specified limits by the allowable operational tolerances, and performance was addressed through the evaluation of the results obtained from volumetric properties and laboratory tests, such as flexural fatigue test, Hamburg wheel-tracking test, and overlay tester. A series of statistical analyses was conducted to develop relationships between the key mix design factors and the observed laboratory performances of each type of mixture. From the analysis, the effects of the main variables on the results of the performance tests used in this study were found. Finally, a statistically-based sensitivity analysis was conducted to reveal the relationship between different tolerance levels and mixture performance for the individual mixtures types.
