Polyurethane-modified asphalt mechanism
Case Studies in Construction MaterialsWith the increasing development of transportation, the demands for the performance and lifespan of asphalt used in road construction have become increasingly stringent. However, most current road asphalt materials exhibit deficiencies in durability. To address the issue of insufficient durability in road asphalt, this paper introduces a novel polymer ...

Application of Cantabrian and Binder Drainage Tests in Designing of Porous Asphalt Binder Content [PDF]
, 2004 Traditional mix design methods which normally incorporate the Marshall test are not appropriate to design porous asphalt because of the insensitivity of the Marshall stability values to variations in binder content.

The improvement of pavement performance using asphalt rubber hot mixes [PDF]
, 2007 The need of a better pavement performance has led researchers to develop new road materials, mainly for the asphalt layers, where the modification of the asphalt is the main example. This modification usually forces the use of polymers and fibers and,

Modified Asphalt Using Buton Natural Rock Asphalt
Journal of Advanced Civil and Environmental Engineeringhe characteristics of asphalt mostly determine how well asphalt pavements work. High temperatures can cause stress on the asphalt surface layer. At high temperatures, irreversible alteration or bubbling occurs and leads to spalling as it travels. This is due to the slow movement of the asphalt components in the pavement mixture, which resists the ...
