Comparative Study of Bitumen Modified by SBS andLDPE (LD-LF0200& LH-0075) abstract
In recent years, different kinds of polymers have been used to modify properties of asphalt mixtures, among them SBS is one of the most widely used which can extremely improve the mechanical properties of asphalt mixtures and bitumen. In order to study the performance of asphalt modified by SBS and the low-density polyethylene (LDPE), one type of SBS and LDPE and one kind of base asphalts are selected according to SHRPindex, and performances of combination of modified asphalt at different percents of modifiers are evaluated. The properties of the LDPE-modified bitumen were compared to mixture with different contents of styrene-butadiene-styrene (SBS) modified-bitumen. The tests showed that to achieve the same performance, as with SBS modified mixture. the LDPE-content must be use a bit higher than SBS. 6%-LDPE(LD-LF0200& LH-0075) modification was determined as the most suitable content according to both binder and mixture tests. ButLPDE is an internal (Iran) production and a very cheap polymer by comparison with SBS.
