Atık LDPE'nin asfaltın fiziksel ve işlenebilirlik özelliklerine etkisi.

In this study, the effect of LDPE, a type of waste plastic, on the physical and workability properties of asphalt was investigated. For this, Triethanolamine (TEOA) chemical up to 2.5% by weight of asphalt was added to B 70/100 pure asphalt to provide an interaction between asphalt and LDPE. Modified asphalts were obtained by adding LDPE in the ratios of 1, 2, 3, 4 and 5% of the asphalt weight to the obtained asphalt-TEOA blend. The physical properties of pure and modified asphalts were first determined by conventional tests such as penetration, softening point, ductility and rolling thin film oven (RTFO). In addition, penetration index (PI) values, which are considered as a measure of the sensitivity of asphalt binders to temperature, were also calculated. Then, the workability properties of the binders were determined by rotational viscometer (RV) test, and their chemical characterization was determined by scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis. According to traditional test result; It was observed that the hardness of the modified binders increased and their temperature sensitivity decreased with the increase of the LDPE additive ratio. According to the results of the RV test, it was observed that the mixing and compression temperatures of the binders increased with the increase of LDPE additive. According to the results of SEM and XRD analysis, it was observed that a chemical interaction between asphalt and waste LDPE was provided and the resulting asphalt-TEOA-LDPE mixture was homogeneous and single-phase.
