This book was released on 1996 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Army Cold Regions Research and Engineering Laboratory is developing a mechanistic pavement design procedure for use in seasonal frost areas. The procedure was used to predict pavement performance of some test sections under construction at the Mn/ROAD facility. Simulations were conducted in three phases, investigating the effects on predictions of water table position, subgrade characteristics, asphalt model, and freeze season characteristics. The procedure predicted significantly different performance by the different test sections and highly variable results depending on the performance model applied. The simulated performance of the tests sections also was greatly affected by the subgrade conditions, e.g., density, soil moisture, and water table depth. In general, predictions for the full depth asphalt sections indicate that they will not fail due to cracking, but two of the three criteria for subgrade rufting indicate failure before the five or 10 year design life of the sections. Conventional sections are predicted not to fail due to subgrade rutting; however, sections including the more frost susceptible bases in their design are predicted to fail due to asphalt cracking relatively early in their design life, and sections with nonfrost susceptible bases are predicted to fail towards the end of the design life.

This book was released on 1998 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study utilized Illinois DOT (IDOT) mechanistic-empirical (M-E) technology and Mn/ROAD mainline pavement section data and information to verify/refine/modify IDOT M-E analysis and design concepts and procedures for full-depth asphalt concrete (FDAC) and conventional flexible pavements (CFP). The Mn/ROAD mainline flexible pavements include eleven CFP and three FDAC pavement sections. Four different granular materials were used in the conventional flexible pavements. A fine-grained soil subgrade (R-value of about 12) is present throughout the mainline. Laboratory material testing results, field distress measurements, and FWD test data were used to study pavement deflection response and performance (rutting and asphalt concrete fatigue). The study demonstrated that the IDOT M-E analysis and design procedures for FDAC and CFP sections are adequate. The ILLI-PA VE structural model adequately predicts the pavement responses. The use of bi-linear (arithmetic) subgrade model and the "theta" granular material model ILLI-PA VE inputs closely replicate CFP field FWD deflection responses. The effect of granular material quality on CFP deflection response is very limited. The ILLI-PAVE FWD backcalculation algorithms are adequate for estimating the moduli of asphalt concrete and sub grade soils.
Book Synopsis Significant Findings from Full-scale Accelerated Pavement Testing by : Wynand JvdM. Steyn
Download or read book Significant Findings from Full-scale Accelerated Pavement Testing written by Wynand JvdM. Steyn and published by Transportation Research Board. This book was released on 2012 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: "TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 433: Significant Findings from Full-Scale Accelerated Pavement Testing documents and summarizes significant findings from the various experimental activities associated with full-scale accelerated pavement testing (f-sAPT) programs that have taken place between 2000 and 2011. The report also identifies gaps in knowledge related to f-sAPT and where future research may be needed. NCHRP Synthesis 433 is designed to expand the f-sAPT base of knowledge documented in NCHRP Syntheses 325 and 235, both with the same title of Significant Findings from Full-Scale Accelerated Pavement Testing. f-sAPT is the controlled application of a wheel loading, at or above the appropriate legal load limit, to a pavement system to determine pavement response in a compressed time period. The acceleration of damage is achieved by one or more of the following factors: increased repetitions, modified loading conditions, imposed climatic conditions, and thinner pavements with a decreased structural capacity which have shorter design lives"--

Download or read book Mechanistic-empirical Evaluation of the Mn/Road Low Volume Road Test Sections written by Navneet Garg and published by . This book was released on 1998 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study utilized I DOT mechanistic-empirical (M-E) procedures and Mn/ROAD low-volume road (LVR) data and information to verify/refine/modify analysis and design concepts and procedures for L VR flexible pavements. The Mn/ROAD L VR flexible pavements include conventional flexible, full-depth asphalt, surface-treatment and aggregate-surface sections. Laboratory test results, field distress measurements, and FWD test data were used to study the affect of granular material quality on pavement performance and deflection response. The results from the rapid shear tests, permanent deformation tests and field rutting measurements show that granular material rutting potential can be characterized by a rapid shear triaxial test at 15-psi confining pressure. For conventional flexible pavements, granular material quality did not affect the pavement deflection response, but material quality effects were significant for aggregate-surface and surface-treatment pavements. ILLI-PAVE predicted pavement responses were fairly accurate for sections with thicker asphalt concrete surfaces. The FWD deflection basin parameter AUPP (Area Under Pavement Profile) can be used to predict the strains at the bottom of AC layer. Effect of subgrade type on pavement response and performance was studied. Sandy subgrades showed little or no change in pavement structural response due to spring-thaw effects. For the cohesive subgrade sections, moisture changes and spring-thaw effects increased surface deflections. The study showed that the lOOT LVR flexible pavement mechanistic-empirical design concepts and procedures are valid and adequate.
