Using the Existing Pavement In-Place and Achieving Long Life (SHRP 2 Prepublication Report*)
|
|
Greetings!
During the last 20 years, numerous infrastructure renewal projects have either modified the existing pavement in place or placed a new structural pavement on top of the existing pavement. SHRP 2 Project R23 (Using Existing Pavement in Place and Achieving Long Life) developed reliable procedures for identifying when an existing pavement can successfully be used in place and how to incorporate it into the new structural pavement to achieve long life. The products include decision matrices, design tables, interactive software, and resource documents that provide valuable information regarding all aspects of a renewal project including project assessment, renewal selection, design, specifications, and construction. The final report documents these activities.
* To make research available as early as possible, SHRP 2 is temporarily posting final reports that have been submitted by the research team, reviewed according to the relevant National Academy of Sciences procedures, and accepted for publication. These prepublication drafts, which have not been edited or formatted for publication, will be replaced by the final versions as they complete the editorial process.
