Minimum 10 years Required Pavement Sectionalization
Pavement sectionalization involves analytical sections – sections with uniform pavement type and thickness, traffic loading, and pavement condition. For practical reasons and constructability, the analyzed sections are combined for pavement rehabilitations. Other factors such as schedule, geometry constraints, project needs other than pavement, and budget during PE and FE need to be considered before final pavement design recommendation.

Pavement Recommendation
Surface Distress Index (SDI): 1.84 Existing International Roughness Index (IRI): 128 in/mile 20 years design ESAL’s: ~ 34.93 million for composite pavement &
22.46 million for flexible pavement in the northbound direction and 28.57 million and 18.30 million in the southbound direction.
Treatment Performance: last treatment performed on this section was mill 2” and pave 2” Surface Course in 2005
Overlay Design consisted of milling 3” depth and resurfacing with:• 2” Stone Matrix Asphalt 12.5 MM Surface Course• 1” Binder Rich Intermediate Course, 4.75 MM
![Page 17: Route 1 - njapa.com](https://reader034.vdocument.in/reader034/viewer/2022050207/626db9c2e024ae1d797d7311/html5/thumbnails/17.jpg)
Binder Rich Intermediate Course, 4.75 MM
Evaluated changes in SDI to evaluate performance of BRIC on NewJersey pavement sections
BRIC analysis is difficult as it is always overlaid with a surfacecourse• Compared performance with and without BRIC• Compared performance with different surface courses• Compared performance life for different scenarios
Performance of BRIC material highly dependent on the surfacecourse overlaying the BRIC
