"Long-term monitoring efforts have been carried on for a number of years at state and national level and have been generally accepted. However, the shape that it takes in the future will depend very largely upon the decisions that are made in this Workshop concerning the following very basic issues: (1) What questions related to the financing management of the nation's highways need to be answered and can only be answered with a continuing data monitoring effort? (2) What data need to be collected and evaluated in order to answer these questions? (3) What is the best way to collect and evaluate these data in order to answer a number of basic and important questions? The deterioration of the highway infrastructure and the consequent need to use tax dollars wisely to maintain, rehabilitate, and reconstruct the highway system have presented the highway community, the state and national governments with basic policy and technical questions to which, at present, there are only tentative or intuitive answers. Rehabilitated or reconstructed pavements are more difficult to design and construct properly than are new pavements. The composition of the vehicle fleet and vehicle loading distributions, the construction of tires, and the magnitude and distribution of tire pressures are changing rapidly and are expected to have a significant impact on the rate of highway deterioration. There is a growing recognition of the importance of climatic influences on the rate of pavement deterioration. All of these changes have created a dynamic situation for policy-makers who are attempting to determine cost responsibilities for different highway users and to define equitable means of apportioning the funds that are available for preserving our nation's highway network"--Technical report documentation p.

Download Long Term Monitoring of Broken and Seated Pavements Book in PDF, ePub and Kindle
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.

Download Long-term Pavement Performance Inventory Data Collection Guide Book in PDF, ePub and Kindle
The primary purpose for this data collection guide is to provide a uniform basis for data collection during long-term monitoring of the performance of pavement test sections under study by the Long-Term Pavement Performance (LTPP) Program. It is a revision to chapter 2 of the 1993 LTPP Data Collection Guide. Inventory data include that data necessary to: 1) identify the test section, 2) describe the geometric details of its construction and the material properties of its structural constituents, and 3) identify construction costs and costs of subsequent maintenance and repair before the long-term monitoring effort. These data are intended to describe the pavement test section at the time the section was included in the LTPP study.
