MODIFIED ASPHALT COMPOSITION AND ASPHALT ROADBED FOR RAILWAY

摘要

Provided is a modified asphalt composition for a railway and an asphalt roadbed, which is capable of increasing recovery speed and hardness during loading as providing elasticity and temperature sensitivity for asphalt for a railway, and improving resistance with respect to a change in plasticity by minimizing a change of material properties of a binder with respect to the temperature. In addition, as a modified asphalt binder for a railway manufactured through a bonding by a chemical composition of a modifying agent and an additive, the composition is capable of improving adhesive power of an aggregate and water resistance, removing toxic odors, securing stable quality so as to prevent deterioration in quality caused by a modification of asphalt in accordance with the passage of time, and improving workability as considering delivery and storage to a plant construction after manufacturing a binder with a wet method considering workability.
