Investigating The Effect of Acrylic Latex on Moisture Susceptibility of Hot Mix Asphalt

Özet

Polymers are popular materials as an additive to improve the performance of hot mix asphalt (HMA). To this aim, acrylic latex was chosen to improve the performance of asphalt mixture. In this study, it was investigated that the performance of hot mix asphalt with acrylic latex additive in three percentages(1%, 2% and 3%). Designbitumen contents were determined for all acrylic latex additive. Indirect Tensile Strength and moisture susceptibility of acrylic latex added HMA was conductedusingtest procedure of AASHTO T283. According to the results, designbitumen contents were increased by acrylic latex. Although the bitumen content was increased, both the indirect tensile (IDT) strength and the moisture resistance were improved by acrylic latex. Best performance was obtained by 3% acrylic latex additive. It is suggested that the percentage of acrylic latex would be increased for further researches.
