Effect of Adding Polymers on The Mechanical Properties of HMA Mixtures - Softcover

Inhaltsangabe

This study demonstrates the ability of improving the performance of asphalt mixtures produced in the local asphalt plants using different types of polymers obtained from plastic waste in Mosul landfills using both wet and dry processes. Two materials were used in the wet process,(PET) and (PS) with percentages (1-5)% by weight of asphalt binder. (PET) and (LDPE) materials were used in the dry process with percentages (0.25, 0.5, 0.75 and 1.0)% by weight of aggregates. For the purpose of comparing the efficiency of the local additives with the efficiency of the global additives available, (Pellet Pave) which is a commercial additive was used in the dry process with a percentage 1% by weight of asphalt mixture according to the manufacturer's recommendations. The performances of modified asphalt and asphalt mixtures were evaluated by conducting several fundamental tests such as rheological properties, stripping and storage stability. Marshall Stability test, moisture susceptibility, durability test known as Cantabro Loss and flexural test were conducted on modified and unmodified asphalt mixtures.
