The primary objective of this paper is to provide data comparing chip and scrub seal treatments with those for control sections of a low-volume flexible pavement in Mississippi, where a falling weight deflectometer (FWD) was used to evaluate the change in the effective structural number over approximately 1 year. The analysis combined portions of approaches from Arkansas, North Carolina, and Texas and resulted in a technique well suited for the test section. The approach used in the 1993 AASHTO Guide for Design of Pavement Structures is included for comparison. A secondary objective is to compare the results computed from the two analysis techniques. The analysis included in this paper appears to be more conceptualized than past analyses of the use of the FWD for evaluation of seal treatments. Results of testing and analysis showed that both the chip and scrub seal treatments preserved the structural number of the pavement better than the structural number on the control sections was preserved, but no appreciable differences between seal types were observed.
