This book was released on 2006 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the details of a study conducted by Infrastructure Management and Engineering (INFRAME) to review condition of selected break and seat (B/S) and rubblization projects constructed by Ohio Department of Transportation (ODOT), and also to demonstrate the ability of various pavement breakers to produce desired breaking patterns and fractured particle sizes required by ODOT specifications. A program of field evaluations was undertaken on four test projects. The pavement on SR-4 was rehabilitated in 1993 by breaking the underlying jointed reinforced concrete pavement with a pile hammer prior to constructing an asphalt overlay. The pavement on SR-36 project was rehabilitated in 1992 by rubblizing the existing jointed concrete pavement with a Resonant Pavement Breaker (RPB) and constructing an asphalt overlay. The continuous concrete pavement on I-70 was rubblized in 2005 with a Multi Head Breaker (MHB), in preparation for an initial asphalt overlay. On the I-71 project, MHB was used to demolish the existing jointed reinforced concrete pavement and demonstrate the capabilities of MHB to produce various fracturing patterns. At each test site, a test pit was dug and a visual assessment of the condition of the fractured pavement overlay and subbase/subgrade was made. Measurements were made of the fracturing pattern at the surface of the concrete and gradation tests were performed to determine the particle size distribution at various depths within the fractured slab. Deflection tests were performed to determine the effect of the observed breaking patterns on the stiffness of the pavement layers. Examination of test pit material indicated that the pile hammer used in constructing the B/S sections on the SR-4 project did not provide the vertical through cracking and steel debonding required by the project specifications. Despite this, the overlay on the B/S section provided vastly superior reflection crack performance than the untreated control section. The MHB equipment used on I-70 appeared capable of providing the breaking patterns and particle sizes required by ODOT specifications. However, the MHB equipment used on I-71 by a different contractor did not produce the desired results; a significant amount of large, un-cracked pieces were observed particularly below the reinforcing steel, regardless of desired breaking pattern. On the other hand, the Resonant Pavement Breaker (RPB) equipment used on SR-36 produced fractured particle size distribution and steel debonding required by ODOT specifications. The principal recommendation of the study is to improve ODOT's specifications for fractured slab techniques. On all types of fracturing projects, the quality control requirements need to be modified to require that test pits be more frequently used to ensure that the specified particle size distributions are in fact being achieved throughout the depth of the slab. On rubblize projects, the present particle size distribution requirements need to be re-examined to ensure that the fracturing operation will avoid, not merely delay, reflection cracking in the subsequent overlay.

Available in PDF, EPUB and Kindle. Book excerpt: Deterioration in Portland Cement Concrete (PCC) pavements can occur due to distresses caused by a combination of traffic loads and weather conditions. Hot mix asphalt (HMA) overlay is the most commonly used rehabilitation technique for such deteriorated PCC pavements. However, the performance of these HMA overlaid pavements is hindered due to the occurrence of reflective cracking, resulting in significant reduction of pavement serviceability. Various fractured slab techniques, including rubblization, crack and seat, and break and seat are used to minimize reflective cracking by reducing the slab action. The main objective of this project is to develop a mechanistic-empirical (ME) design aproach for the HMA overlay thickness design for fractured PCC pavements. In this design procedure, failure criteria such as the tensile strain at the bottom of HMA layer and the vertical compressive strain on the surface of subgrade are used to consider HMA fatigue and subgrade rutting, respectively. The developed ME design system is also implemented in a Visual Basic computer program.

This book was released on 2002 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of an evaluation of concrete slab fracturing techniques as a means of arresting or retarding reflective cracking through asphalt overlays placed on severely distressed portland cement concrete pavement. The study involved monitoring the performance of five pavement rehabilitation projects over a period of up to 8 years. Two of the projects were originally constructed of jointed plain (unreinforced) concrete, and the other three consisted of jointed reinforced concrete pavement. The test sections were fractured with a guillotine drop hammer and then seated with a 50-ton pneumatic tire roller. For comparative purposes, control sections, which were not fractured prior to placement of the asphalt overlay, were constructed just beyond the bounds of three of the fractured test sections. Detailed visual condition surveys were conducted annually at all sites. For each survey, the number of occurrences of reflective cracks that formed in fractured sections was directly compared to the number of cracks observed in the control sections to quantify the tendency of fracturing to retard or arrest the formation of reflective cracks. The results of this study show that fracturing and seating distressed concrete pavements appear to be an effective means of retarding the formation of reflective cracking through asphalt overlays on jointed, unreinforced pavements. In the case of reinforced pavements, however, the fracturing technique was somewhat less successful in that the formation of reflective cracks appeared to be delayed for only about 3 years. Beyond that point in time, the fractured reinforced sections exhibited approximately the same amount of reflective cracking as the control section. The researcher concludes that any observed benefit in terms of extended pavement service life or enhanced ride quality resulting from even a slight delay in reflective crack propagation would likely offset the rather nominal cost of the fracturing and seating operation itself.

This book was released on 2023-05-25 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable development of smart cities infrastructures is of paramount importance and need to be planned, designed, constructed, operated and de-commissioned in a manner that ensures economic, social, environmental and institutional sustainability over the entire infrastructure life cycle. Smart cities infrastructure however be cost effective, disaster resilient, environmentally friendly, conserving natural resources, and sustainable ensuring faster delivery of quality and durable structures which include roads, building, bridges, energy and water infrastructures. Government of India is going to encourage Public Private Partnership (PPP) as an alternate option to build most of the infrastructures, which can be useful both for green-field as well as brown-field smart cities projects. The present book is a collection of contributed research and review papers presented at the ‘National Conference on Sustainable Development of Smart Cities Infrastructure’ (SDSCI-2023) held at National Institute of Technology, Kurukshetra in May 2023.The subject matter is grouped into nine sessions which include research articles pertaining to sustainable development of smart cities, urban and rural planning, transportation, built environment and management, sustainable and smart technologies, materials, construction and maintenance, advance modelling, characterization of structures, energy and environment, performance of smart cities infrastructure under extreme loading conditions, green buildings, structural health monitoring, and ICT in smart cities, data mining and machine learning for sustainable infrastructure, GIS and remote sensing, future trends and prospects of smart cities, innovative technologies, building energy and efficiency and sobriety, and sustainable resilience to natural and man-made disasters, and smart materials, etc. The book would be a valuable reference for researchers, students, structural designers, site engineers, and all related engineers involved in the field of sustainable development of smart cities infrastructure.
