The Effects of Peat Modified Asphalt Binder Concentrations on Viscoelastic Properties
In this study, the viscoelastic properties of Peat partials used to modify asphalt binders are investigated. The tests were implemented in the current study using a dynamic shear rheometer (DSR). The obtained results from the rheological tests were represented by both complex moduli (G*) and viscosity (δ) under different conditions by Isochronal Plot, Black Diagram Plot, and Surface free energy SEF. The rheological properties of modified types of binder showed better performance than unmodified binder PNpt.M.A 0 at intermediate temperatures based on the results of DSR. Different proportions of Parit Nipah Peat (PNpt) to original asphalt binder had improved. The influence of Parit Nipah Peat (PNpt) on the original binder was significantly more significant than the unmodified asphalt binder or original asphalt binder. It was found that the addition of PNpt had positive effects and the addition of modifier with PNpt.M.A 5 revealed the best results. In conclusion, the Parit Nipah Peat modified asphalt reduced temperature susceptibility and increased the hardness of asphalt. PNpt.M.A 5 showed the most substantial effect among all samples, according to the results.
