Vol. 1 documents the results of backcalculation of layer material properties for rigid pavements included in the Long Term Pavement Performance (LTPP) program in the United States and Canada using deflection testing data. Vol. 2documents the procedure and steps used to back-calculate the layered elastic properties (Young's modulus and the coefficient and exponent of the nonlinear constitutive equation) from deflection basin measurements for all of the Long-Term Pavement Performance (LTPP) test sections with a level E data status.

"This report documents the results of backcalculation of layer material properties for rigid pavements included in the Long Term Pavement Performance (LTPP) program in the United States and Canada using deflection testing data. This study backcalculated the layer material properties for rigid pavements using the slab on elastic solid foundation and the slab on dense-liquid foundation procedures. The "best fit" algorithm was used after consideration of alternative methods of backcalculation. Pre-processing and post-processing utility software were developed to facilitate data handling. The backcalculation analysis was conducted for all General Pavement Studies (GPS), Special Pavement Studies (SPS), and Seasonal Monitoring Program (SMP) test sections. Data tables that include backcalculation parameters were developed for inclusion in the LTPP Information Management System (IMS). Key findings include the following: 1. The "best-fit" method was selected as the primary backcalculation method for both dense-liquid (DL) and elastic solid (ES) subgrade models. 2. Reasonable backcalculation results were obtained for the large majority of GPS, SPS, and SMP sections. Typical modulus values and ranges are provided for the PCC slab, many types of bases, and the subgrade. 3. Strong correlations were found between backcalculated parameters using DL and ES subgrade models. 4. Temperature curling during the day had a profound effect on the results of backcalculation [making it important to conduct falling weight deflectometer (FWD) basin testing early in the morning to reduce variability in backcalculated values]. 5. Poor correlation was found between backcalculated and laboratory elastic moduli of the concrete slab. 6. A bonded interface between the slab and base produced the best layer moduli for a large majority of the sections (center slab backcalculation)"--Tech. report doc. page.

Bearing Capacity of Roads, Railways and Airfields includes the contributions to the 10th International Conference on the Bearing Capacity of Roads, Railways and Airfields (BCRRA 2017, 28-30 June 2017, Athens, Greece). The papers cover aspects related to materials, laboratory testing, design, construction, maintenance and management systems of transport infrastructure, and focus on roads, railways and airfields. Additional aspects that concern new materials and characterization, alternative rehabilitation techniques, technological advances as well as pavement and railway track substructure sustainability are included. The contributions discuss new concepts and innovative solutions, and are concentrated but not limited on the following topics: · Unbound aggregate materials and soil properties · Bound materials characteritics, mechanical properties and testing · Effect of traffic loading · In-situ measurements techniques and monitoring · Structural evaluation · Pavement serviceability condition · Rehabilitation and maintenance issues · Geophysical assessment · Stabilization and reinforcement · Performance modeling · Environmental challenges · Life cycle assessment and sustainability Bearing Capacity of Roads, Railways and Airfields is essential reading for academics and professionals involved or interested in transport infrastructure systems, in particular roads, railways and airfields.
