Appendix C. Summary of Level 3 and Level 2 Cracking Data of Each Zone C 1

Appendix C. Summary of Level 3 and Level 2 Cracking Data of Each Zone In this section, the Level 3 and Level 2 cracking data for each Zone on other five asphalt sites are summarized. For each site, a pair of figure and table will be provided to present the detailed cracking data of each Zone. In tables of Level 2 cracking data for each site, “L” is Low Severity Cracking Percent, “M” is Medium Severity Cracking Percent, and “H” is High Severity Cracking Percent.

New definitions will help pavement cracking survey providers and pavement engineers at state highway administrations conduct objective cracking measurements and encourage continuing technological innovations by researchers and vendors.

The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 288: Standard Definitions for Common Types of Pavement Cracking helps develop standard, discrete definitions for common cracking types for asphalt and concrete pavements.

The standard definitions would be used to facilitate comparable measurement and interpretation of pavement cracking.
