Book excerpt: "The thirteenth full-scale Accelerated Pavement Test (APT) experiment at the Civil Infrastructure Laboratory (CISL) of Kansas State University aimed to determine the response and the failure mode of thin concrete overlays. Four pavement structures were built and tested in this experiment: two Thin Concrete Overlays (TCO) pavements, with 4-inch and 6-inch thick overlays constructed on a 5-inch thick PCCP and two Thin Whitetopping (TWT) pavements, with 4-inch and 6-inch thick PCC overlays constructed on a 5-inch hot-mix asphalt layer. The pavements were instrumented to measure the strains at selected locations in each PCC overlay. Each of the four pavements was loaded with approximately two million passes of the CISL APT machine, under in-door ambient temperature condition. No moisture was added to the pavements. Response measurements and performance evaluations were performed at about every 100,000 passes. The TCO overlays failed due to the loss of support underneath the concrete slab which caused transverse cracks to develop in both 4- and 6-inch PCC overlays. No loss of bond between the PCC overlay and the supporting slab was observed. The 4-inch TWT exhibited a transverse crack at the middle of the slab, while the 6-inch TWT exhibited no cracks at the end of testing. The theoretical strains in the concrete overlays at the locations where instrumentation was installed were computed with the ANSYS Finite Element Method (FEM) software. It was found that the magnitude and shape of computed strains matched well with those of the strains measured before any APT loads were applied. It was, therefore, concluded that the three-dimensional finite element model built and the assumption made (linear elastic materials, fully bonded overlays) can accurately estimate the response of TWT and TCO pavements under wheel loading. In addition, the FEM can be used to estimate the evolution of lineal extent of the loss of support under the joints by comparing the measured strains with the corresponding computed strains"--Technical report documentation page.

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"--

This book was released on 1996 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis, which describes the state of the practice for full- scale accelerated pavement testing (APT), will be of interest to state department of transportation (DOT) pavement design and materials engineers; DOT research staff, including field and laboratory materials testing personnel; and private industry APT equipment suppliers. State DOT administration and management personnel will have a particular interest in the application of APT results toward more efficient and effective pavement designs. Local transportation agencies may also have an interest in the topic. This synthesis reviews the capabilities and limitations of the major APT facilities available worldwide and describes the role and application of full-scale accelerated pavement testing in the development of pavement technology. This report of the Transportation Research Board (TRB) presents data obtained from a review of the literature and a survey of the state DOTs, Canadian transportation agencies, and international organizations. A brief historical overview of APT, a discussion of the application of APT to research, and the application of APT to practice are included. Profiles of APT facilities throughout the world are included in an appendix.

Available in PDF, EPUB and Kindle. Book excerpt: The Midwest States Accelerated Pavement Testing Pooled Fund Program, financed by the highway departments of Missouri, Iowa, Kansas and Nebraska, has supported an accelerated pavement testing (APT) project to compare the performance of stabilized clayey embankment soil when Portland cement, fly ash, lime and a commercial product were used as stabilizing agents. The project aimed to improve the practices related to the design of flexible pavements when the top of the subgrade is improved by chemical stabilization. The experiments were conducted at the Civil Infrastructure Systems Laboratory (CISL) of Kansas State University. The test program consisted of constructing four flexible pavement structures and subjecting them to full-scale accelerated loading test. The study indicated that cement and lime are the most effective stabilizers for the studied soil. These stabilizers resulted in lower vertical compressive stresses at the top of the subgrade and lower rut depth at the pavement surface than the fly ash-treated soil. After more than two million axle load repetitions, the pavement with cement stabilized embankment soil exhibited much less surface cracking than the pavement with fly-ash stabilized embankment. The commercial product proved not to be effective in stabilizing the non-sulfate clayey soil used in this experiment, when the embankment is constructed at the same moisture content and compaction level as for the other three chemicals. The unconfined compression strength measured on laboratory prepared samples of soil stabilized with the commercial chemical compound was very similar to that of the untreated soil.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of the research was to compare the performance of fiber reinforced and plain Portland Cement Concrete (PCC) overlay when used as a thin non-dowelled overlay on top of a rubblized, distressed concrete pavement. The experiment was conducted at the Accelerated Testing Laboratory at Kansas State University, and consisted of constructing two pavements and subjecting them to full-scale accelerated pavement test. The pavements were constructed in the environmental pit so that heat-cool temperature cycles were imposed. The two pavements were subjected to 500,000 full-truck axle passes. Stresses and strains at several locations in the two pavements, as well as the expansion/contraction of the slabs, were periodically recorded during the test. The stress-strain data, as well as the location, severity and extent of the cracking in the overlay, clearly indicate that there is no benefit of including the plastic fibers in the concrete overlay. The full-scale accelerated test revealed that the thin non-dowelled overlays are effective when used on top of distressed, rubblized concrete pavements.
