LABORATORY COMPARISON OF EVA BASED RESIN AND SBS MODIFIED BITUMINOUS BINDER
Abstract
Although the bitumen used too few in the asphalt concrete it is
significantly liable to the performance of pavement. For this reason bitumen is
frequently modified in order to enhance the performance of asphalt mixtures.
SBS is a widely used polymer modifier for asphalt binders to improve the
performance properties of hot mix asphalt. SBS is nearly indispensable when the
binder properties do not satisfy the specification requirements under hot
service temperatures. In this study the performance of an alternative additive
named as ethylene vinyl acetate (EVA) based resin (EBR) to SBS was
investigated. The SBS contents were kept constant at 3% and EBR contents were
2%, 3% 4% and 5% by weight of base bitumen. Modified
binders were produced by mixing a 50/70
penetration grade base bitumen with SBS and
EBR. Penetration, softening point, rotational viscometer tests were
conducted to base and modified binders and results
were compared with each other. In conclusion it was determined that EBR
content have to be more than 3% in order to obtain the same performance with 3%
SBS modification. 3% EBR modification gave satisfactory performance in terms of
temperature sensitivity, high temperature resistance and workability.
