Title: SUMMARY OF ASPHALT ADDITIVE PERFORMANCE AT SELECTED SITES
Accession Number: 00625143
Record Type: Component
Availability: Find a library where document is available Abstract: In 1990, a survey of modified asphalt test pavements was conducted to examine performance during construction and service while using the various additives on the market. Representatives from 14 states, Austria, and Canada were contacted to survey the field performance of more than 30 end-to-end test pavements where one to five asphalt additives, modifiers, or modification processes have been evaluated. States contacted include Alabama, California, Colorado, Indiana, Louisiana, Maine, Minnesota, Montana, New Jersey, Texas, Utah, Vermont, and Virginia. Additives include styrene butadiene rubber (SBR) latex, Styrelf-13 (SBR reacted with asphalt), DuPont neoprene latex, styrene butadiene styrene block copolymer (Shell Kraton), polyethylene (Novophalt process), ethylene vinyl acetate (Exxon and DuPont), Solar Laglugel (nylon resin polymer), Gilsonite, asphalt-rubber (tire rubber), Dow polymers (unknown), Plus-Ride (ground tire rubber replacing aggregate), Microfil-8 (pelletized carbon black with oil), Celite (diatomaceous earth), Chemkrete, hydrated lime, fly ash, Acra 500, and fibers. Most of the results have been collected by telephone and are, therefore, qualitative. Some of those contacted have sent written reports that provide more quantitative data. Unfortunately, many of the test pavements are less than 5 years old and show no differences in performance.
