This is the new and revised edition, which has been developed to provide the state-of-the-practice for evaluating and designing asphalt overlays for both asphalt and concrete pavements. Emphasis has been placed on alternatives to combine sound pavement management principles, accurate distress identification, and a detailed structural analysis for an asphalt overlay design to carry the projected vehicular loading.

This new edition has been rewritten to reflect changes in rehabilitation strategies that took root in the late 1980s and early 1990s.

• Chapter 1 has been written to capture the asphalt applications available to meet demands placed on an aging national highway infrastructure.
• Chapters 6 and 10 on Nondestructive Testing and Fractured Slab Technology respectively have been added.
• Chapters 12, 13 and 14 have been developed as Guide Specifications for the more popular rehabilitation techniques for concrete pavement - Rubblization, Crack/Break and Seat, and Saw-Cut and Seal.
• Chapter 15 on Drainage has been expanded to include the latest innovations using longitudinal edge drains and permeable bases for use in conjunction with rehabilitation of concrete pavements.
