Download or read book Nondestructive Testing of Pavements and Backcalculation of Moduli written by ASTM Committee D-18 on Soil and Rock. Subcommittee D-4 on Road and Paving Materials and published by ASTM International. This book was released on 1994 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of June 1993 international symposium held in Atlanta, Georgia, called specifically to develop and standardized evaluation procedures for non-destructive methods of testing pavements. The 29 papers discuss analytical models and techniques, measurement and calculation techniques in the field and laboratory, problems and errors associated with backcalculation methods and design parameters, and testing for other pavement uses. Also includes a history of the quest for a standard and the status of that effort. Reproduced from typescripts. Annotation copyright by Book News, Inc., Portland, OR

Available in PDF, EPUB and Kindle. Book excerpt: The impact hammer compaction has historically been used to develop moisture-density curves and fabricate specimens for strength testing for flexible base and subgrade materials. However, the precision of compressive strength results by the impact hammer compaction remains a concern that can result in conflicting test results on whether a material meets specification requirements. This project used the Superpave Gyratory Compactor (SGC) to analyze if SGC compaction enables improved precision of compressive strength tests for flexible base and subgrade materials and analyzed a procedure for determining the moisture-density curve of base and subgrade materials using the SGC. Also, the applicability of SGC for base materials was evaluated in context of mechanistic-empirical (M-E) pavement design methods. The results showed that SGC compaction produced compressive strength results with less variability and improved precision compared to impact hammer compaction. Also, from the measurement of M-E properties, base materials compacted with the SGC were associated with lower permanent strain and higher resilient modulus than the materials with the impact hammer. The evaluation of internal structure using X-ray Compute Tomography and Aggregate Image Measurement System helped explain the behavior ofmaterials compacted with both impact hammer and SGC compaction methods.

Book excerpt: Tests were performed to determine the effect of three gyratory compactor variables (angle of gyration, vertical pressure, and number of revolutions) on the compaction characteristics of lean clay. The lean clay was also compacted by the impact compaction method for comparison with the gyratory compaction results. These data are to be used for an analysis exploring the use of the gyratory compactor in the design of pavement structures for present and future traffic.
