Effect of linear low density-polyethylene grafted with maleic anhydride (LLDPE-g-MAH) on properties of high density-polyethylene/styrene–butadiene–styrene (HDPE/SBS) modified asphalt
Highlights A kind of asphalt modifier was prepared by melt blending. The low-temperature performance of HDPE/SBS modified asphalt was improved. Softening points difference between the top and bottom sections of samples were sharply reduced. LLDPE-g-MAH had no significant effect on high-temperature property and rheological character.
Abstract A kind of modifier composed of high density-polyethylene (HDPE) and styrene–butadiene–styrene (SBS) was prepared by melt blending with different contents of linear low density-polyethylene grafted with maleic anhydride (LLDPE-g-MAH). HDPE/SBS modified asphalt composites were prepared. Effects of LLDPE-g-MAH on classical performance, hot storage stability, and dynamic rheological behaviors of HDPE/SBS modified asphalt were investigated. Compared with samples without LLDPE-g-MAH, penetration and ductility of HDPE/SBS modified asphalt were both increased, in the meantime, softening point and the maximum failure temperature were decreased. The research results showed that low-temperature performance was improved, while LLDPE-MAH had no positive effect on high-temperature property. In addition, softening point difference between the top and bottom sections of samples was sharply reduced. A fairly homogeneous dispersion system of the modifiers in the asphalt matrix was observed by microscope. A conclusion that LLDPE-g-MAH had no significant effect on high-temperature property and rheological character can be drawn from the rheological studies.
