Available in PDF, EPUB and Kindle. Book excerpt: A mechanistic design procedure for Full-Depth asphalt concrete AC pavements for highways is proposed and validated. The procedure is based on ILLI-PAVE, a stress dependent finite element computer program, coupled with appropriate transfer functions. Two material design criteria are considered: AC flexural fatigue cracking and subgrade rutting. Fatigue cracking is controlled by limiting the tensile strain at the bottom of the AC-subgrade interface.

Available in PDF, EPUB and Kindle. Book excerpt: Concepts for a mechanistic based thickness design procedure for high strength stabilized base pavements are presented. The proposed procedure is based on stabilized layer fatigue consumption and a ILLI-PAVE based algorithm for estimating stabilized layer flexural stress. The design concept can easily be developed into a comprehensive practical thickness design procedure for Illinois DOT utilization. Appendix A is a State-of-the-Art summary entitled "The Selection of Stress-Strain, Strength, and Fatigue Relationships for use in Mechanistic Design Procedures." Appendix B is an "ILLI-PAVE Data Base for Stabilized Base Pavements."

Available in PDF, EPUB and Kindle. Book excerpt: The basic concepts and the development of a proposed FULL-DEPTH ASPHALT CONCRETE THICKNESS DESIGN PROCEDURE are presented. Traffic (IDOT traffic factor), subgrade modulus (fine-grained soils, granular type soils), location in the state (pavement temperature effects), asphalt cement grade (AC-10, AC-20), and design reliability factors are considered. ILLI-PAVE based design algorithms are utilized in the procedure. Asphalt concrete fatigue consumption is the design criteria. A ''Design Time" concept is used to consider seasonal temperature effects. The procedure can be easily modified to accommodate conditions other than those considered in the procedure presented in Appendix A.

Available in PDF, EPUB and Kindle. Book excerpt: Mechanistic design concepts for conventional flexible pavement (asphalt concrete (AC) surface + granular base/subbase) for highways are proposed and validated. The procedure is based on ILLI-PAVE, a stress dependent finite element computer program, coupled with appropriate transfer functions. Two design criteria are considered: AC flexural fatigue cracking and subgrade rutting. Fatigue cracking is controlled by limiting the tensile strain at the bottom of the AC layer. Subgrade rutting is controlled by limiting the stress-ratio at the granular layer-subgrade interface. Algorithms were developed relating pavement response parameters (stresses, strains, deflections) to AC thickness, AC moduli, granular layer thickness, and subgrade moduli. Extensive analyses of the AASHO Road Test flexible pavement data are presented supporting the validity of the proposed concepts.

This book was released on 1998 with total page 302 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.

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.
