Characterization of Physical Properties and Morphological Ruberized Asphalt Paving Blocks based on Bituminous Coal and Concentrated Natural Rubber Latex

: This research about the characterization physical properties and morphological ruberized asphalt paving block using asphalt as a binder replacement and utilization of natural resources such as bituminous coal and natural rubber latex concentrate (NRLC). This research aims to determine the optimum value of physical properties and learn the effect of morphological control on the paving block that have been prepared. Morphological control with varied the composition asphalt, bituminous coal, and natural rubber latex concentrate that mixed using by an internal mixer with addition of aggregates and additive agents such as dicumyl peroxide as an initiator and divinylbenzene as a crosslinker. After the mixing process, then the mixture on shaping/forming process. The result of physical properties obtained optimum value at the variation of composition asphalt : bituminous coal : natural rubber latex concentrate (70:25:5)(Paving Block E). The percentage of water absorption is 0.85 % and compressive strenght is 154.23 Kgf (0.605 Mpa). At this optimum variation of composition has been characterized the morphological using by Scanning Electron Microscopy (SEM) which is the result of surface morphology showed the mixture compactly and most effective homogenity of the mixture.
