Download or read book Multiple Wheel Heavy Gear Load Pavement Tests Volume III Part A Presentation and Initial Analysis of Stress Strain Deflection and Vibratory Measurements Instrumentation written by Richard H. Ledbetter and published by . This book was released on 1971 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flexible and rigid pavement test sections were constructed and tested to gain information on pavement and soil behavior under large aircraft loadings. These test sections incorporated instrumentation systems designed to determine the response of the pavement structures to static, dynamic (slowly moving), and vibratory loads and to traffic by full prototype loadings. The components of the instrumentation systems, their installation, and the test programs are described in this volume. (Author).

Book excerpt: Flexible and rigid pavements were constructed and tested to obtain data on pavement and soil behavior under large aircraft loadings for use in developing criteria for evaluating and designing airfield pavements subjected to multiple-wheel heavy gear loads (WMHGL). The test sections incorporated instrumentation systems designed to determine the response of the pavement structures to static, dynamic (slowly moving), and vibratory loads and to traffic by full prototype loadings of a 12-wheel assembly (one main gear of a C-5A aircraft), a twin-tandem assembly (one twin-tandem component of the Boeing 747 assembly), and a single wheel. Analysis of static load response data from the flexible pavement instrumentation program resulted in the establishment of maximum elastic deflection and vertical elastic stress versus depth curves. Comparisons showed that the same relationships were true for static and dynamic load tests, as well as for speed tests. The findings for the rigid pavement test section indicated that the Westergaard algorithm can be used for reasonable predictio of pavement response to test loadings. The data from the instrumentation program and the traffic tests were used in the analysis of the flexible and rigid pavement test sections. The analysis resulted in a modification of the basic flexible pavement CBR design method. (Author).

Ledbetter and published by . This book was released on 1971 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flexible and rigid pavement test sections were constructed and tested to gain information on pavement and soil behavior under large aircraft loadings. These test sections incorporated instrumentation systems designed to deteermine the response of the pavement structures of static, dynamic (slowly moving), and vibratory loads and to traffic by full prototype loadings. This volume covers data reduction, analysis, and the findings of the instrumentation and vibratory testing programs; Appendixes A and B contain details of instrumentation measurements for flexible and rigid pavements, respectively.

Available in PDF, EPUB and Kindle. Book excerpt: Instrumented aircraft were used to apply static and dynamic loads to instrumented pavement structures (both flexible and rigid) at the National Aviation Facilities Experimental Center (NAFEC), Atlantic City, N.J. Volume I of this report describes the testing program and instrumentation systems. Volume II with Appendixes A and B presents the reduction and analysis of data and the test results. This volume contains a compendium of the entire study. Measurements of displacement, velocity, pressure and temperature were made in the two pavement structures. Two phases of material behavior, elastic and inelastic, in both flexible and rigid pavement structures were identified. Each phase had to be treated independently for a full analysis of the static and dynamic load test results.
