SUBJECT: "R" Value Testing and Structural Section Design l Interior Streets,
Ma-r y Montaiias, City of Carlsbad, California
The structural sectjons for paving of' Janis Way, Celinda Drive North, Celindq
Drive South, Sara Way, and Maria Lane have been completed. The work was
authorized by Mr. Ca.rl Lynton. The calculated sections for all but Ceiinda ,
Drive South are less than the minimum Ctty standards and the section for {eli'nda
Drive South is the same as the minimum City standard. Consequentl~, .a1]
interior streets will require tne min'imum City standard .. Transmitted herewith
are the "Rn Value test results and pertinent calculations. The final desi·gn for
all interior streets is: .
3 inches AC over 6 inche'5 Class 2 AB
If you have any questions or further'requirements, please notify this office.
