Chip and Scrub Seal Field Test Results for Hwy 17 and Hwy 35

This report contains field test results from two pavements located in Mississippi containing chip seals and scrub seals. Limestone aggregate from the same source was used with PASS-CR emulsion. The pavements were tested at three intervals. One or both of the pavements were tested for: aggregate retention, skid resistance, cracking, bleeding/flushing, rutting, roughness, and structural integrity via a Falling Weight Deflectometer (FWD). Analysis consisted of data interpretation focusing on trends and statistical analysis using existing methods with exception of FWD data. FWD data was analyzed with a method developed for this research that combined key elements from methods of Arkansas, North Carolina, and Texas. Test results showed scrub seals to out perform chip seals. Test results also provided information related to construction practices that were compared to best practices recently released in the form of a national synthesis.
