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.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents details of a study conducted to evaluate the long term performance of asphalt overlays on broken and seated (B/S) concrete pavements, using field expe riments. The primary purpose of this study is to evaluate the effectiveness of breaking and seating as a reh abilitation strateg y for retarding reflection crac king in asphalt concrete (AC) overlays on jointed reinforced concrete pavements. Test sections were constructed by milling the original AC layer, breaking and seating the concrete slabs and constructing new AC overlays. Control sec tions were co nstructed ad jacent to the B /S sections in the same way, but without breaking the underlying concrete slabs. The test sections carried a large volume of traffic. The original pavements selected in this study were fairly uniform with respect to their structural and surface conditions. Two types of pavement breakers were used in this study, namely guillotine and pile hammer. The extent of breaking was closely monitored. The performance of the test sections was monitored for a total period of nine years. The monitoring data included deflection measurements, crack mapping, a pavement condition surveys and roughness surveys on the original pavement and on the overlay. The results, in general, strongly indicate an improved performance of AC overlays on broken and seated concrete pavements. The B/S treatment has a significant effect on the structural response and behavior of the resulting pavement. Breaking the concrete slabs into smaller pieces resulted in a reduction in the flexural strength, an increase in the surface deflection (50% to 100%), and a decrease in AREA and Spreadability (20 to 30%). Breaking and seating has been extremely effective in delaying and minimizing reflection cracking. Hence, the breaking and seating procedure does indeed result in improved pavement performance. Ultimately, economics and serviceability will govern its use, based on the length of time future maintenance and rehabilitation is deferred.

Available in PDF, EPUB and Kindle. Book excerpt: Information was collected from each of the six states in Region 5 of the Federal Highway Administration (FHWA) on the procedures used to rehabilitate jointed concrete pavements. As built plans and specifications were obtained from a number of projects in each of the six states which had been rehabilitated and the performance of the pavements were studied after a number of years in service. Interviews were conducted with personnel of the Departments of Transportation from each state to collect as much information as possible concerning the current practices and techniques used for pavement rehabilitation. Where sufficient data were available, statistical correlations were made of the performance trends as they relate to specific rehabilitation practices. Current practices were compared with earlier practices and efforts made to determine the reasons for the changes. Results show that the performance is closely related to the workmanship in the field and the ingenuity of the engineers involved. Recommendations are presented for each of the rehabilitation techniques studied. Many problems still exist with all of the techniques studied. Further detailed data on the exact procedures and practices used in the field during the rehabilitation and performance after rehabilitation are desperately needed. Better record keeping is sorely needed on both the "as built" conditions and on the performance, so the effectiveness of the various practices can be documented.

Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to pavement designers, maintenance engineers, and others interested in reducing reflection cracking of asphalt overlays on portland cement concrete (PCC) pavement. Information is presented on the technique of breaking or cracking of the concrete pavement into small segments before overlaying with asphalt concrete. Asphalt concrete overlays on existing PCC pavements are subject to reflection cracking induced by thermal movements of PCC pavement. This report of the Transportation Research Board discusses the technique of breaking/cracking and seating of the existing PCC before an overlay as a means to reduce or eliminate reflection cracking.

This book was released on 2009-04-01 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pavement analysis in this study considers various combinations of pavement rehabilitation treatments (two-course HMA overlay with or without surface milling, concrete pavement restoration, three-course HMA overlay with or without surface milling, three-course HMA overlay with crack and seat of PCC pavement and 3-R and 4-R overlay or replacement treatments). Six road functional classes (rural and urban of interstates, non-interstates of the NHS, and non-interstates non-NHS) are considered. This allows for estimation of the performance and service life of the pavement, corresponding to each treatment and road functional class.

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.
