Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to serve the needs of the motoring public. Our system of paved roads and streets has developed steadily over the years. Still, the rapid increase in the number of vehicles has far exceeded the mileage of new roads added to accommodate them. Many of the older pavements are carrying motor vehicles whose volume and weight and speed are far in excess of those for which the pavements were designed. Sharp curves, steep grades, short sight distances, short vertical curves and narrow roadways are among the geometrical deficiencies that limit the pavements capacity and safety. In addition, many pavements, for various reasons, need strengthening; others need surface restoration. The objective of this manual is to propose an economical way to salvage, strengthen, and modernize deficient roads and streets with asphalt concrete.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asphalt overlays can be categorized as pavement rehabilitation structural overlays or pavement preservation overlays in terms of the thickness and timing of maintenance activities. Pavement rehabilitation overlay contributes to the structural enhancement of pavements and pavement preservation overlays generally provide functional improvement to an existing pavement. In recent times, the pavement design approach employed by the Louisiana Department of Transportation and Development (LADOTD) has been transitioning from the 1993 AASHTO design procedure to a locally calibrated Pavement ME method. The AASHTOWare Pavement ME (Mechanistic-Empirical) design procedure is considered the modern approach to pavement design. Significant updates have been introduced in the Pavement ME design software in the past few years. Therefore, this study focused on conducting a local calibration of the Pavement ME procedure for asphalt overlays in Louisiana. In addition, performance evaluation of the asphalt overlays was conducted to determine the factors that would have an impact on their performance. In total, 37 rehabilitation asphalt overlay projects and 33 preservation asphalt overlay projects were selected all over Louisiana with different base types and traffic volumes. These projects consisted of mainly three types of bases: soil cement base, crushed stone base and Portland cement concrete base. The pavement performance data were collected from the Louisiana Pavement Management System (LA-PMS) database and the data regarding geographical location, design thickness, and traffic were retrieved from the LADOTD intranet. The field performance of the asphalt overlays was investigated in terms of several design parameters i.e. base type, traffic level, total Hot Mix Asphalt (HMA) thickness after milling, pavement precondition and overlay service life. Manual calibration of Pavement ME was performed for rehabilitation asphalt overlays and a calibrator assistance tool was adopted for the local calibration of preservation asphalt overlays to calibrate the performance models in terms of typical pavement structure, traffic, and weather conditions of Louisiana. The results showed that the existing pavement condition does have an impact on preservation overlay performance since distress in pavements with poor precondition was observed to be higher. The pavement with good precondition and higher asphalt concrete (AC) thickness exhibited higher service life. A case study was performed to determine the optimal timing of preservation overlay applications based on cost-benefit analysis. Fatigue cracking was under-predicted and transverse cracking was over-predicted by the Pavement ME national model for rehabilitation overlays. For preservation overlays, both the fatigue cracking and transverse cracking were under-predicted. Therefore, the performance models were adjusted through the local calibration to match the field measurement.

Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to pavement designers, maintenance engineers, and others interested in methods and procedures for reducing reflection cracking of asphalt overlays. Information is provided on the use of paving fabrics and membranes in pavement rehabilitation. Reflection cracking of pavement overlays results in decreased pavement performance with respect to ride quality, structural support, skid resistance, and safety. The use of fabrics is one of the alternatives that are available to reduce or delay reflection cracking. This report of the Transportation Research Board describes the experiences of agencies in the use of fabrics and membranes for reduction of reflection cracking.
