A PROPOSAL OF THE PHYSICAL PROPERTY FOR ASPHALT

Abstract

 Asphalt used as a binder for paving materials is usually classified into different categories, according to its manufacturing method and its composition. After being classified into different categories, the asphalt is then grouped into quality grades and sold in the market. Each “category” evaluates the asphalt property according to mutually independent assessment criteria of its own. As a result, both the orderer and the contractor of asphalt pavement work are unable to compare and examine the physical characteristics of asphalt across different categories, which hinders the improvement of asphalt technology. In order to improve the evaluation method of characteristics of asphalt, the force ductility test can be used to assess the physical properties of asphalt using the same estimation method across different category. This research paper investigated the improved force ductility test method, and examined its usefulness as a mechanical evaluation method of pavement asphalt.
