Advancement of Profile-Based Curl and Warp Analysis Using Long-Term Pavement Performance (LTPP) Profile Data

Project Information

Project ID: 
FHWA-PROJ-14-0130
Project Abstract: 

This project will expand the work presently limited to one project across a variety of Long-Term Pavement Performance (LTPP) test sections representing typical climates and regions of the United States. Ideally, relationships will be established that will allow more limited datasets to still predict the impact of curl and warp on overall pavement roughness measurements. While this is not guaranteed, it is certain that performing these analyses on a broader dataset will result in improved knowledge regarding the sections in question and additional data in the LTPP Pavement Performance Database (PPDB) that will support future research. In addition, and investigation of potential uses of Falling-Weight Deflectometer (FWD) data knowing the curl-and-warp properties of a pavement will be performed.

Goals:

The project will expand the analysisto Long-Term Pavement Performance (LTPP) projects in different climates, to build models to predict curl and warp based on environmental and structural factors, and to examine the contribution of curl and warp to the structural response of the pavement system.
