Abstract Since the beginning of modern road construction, there have been effort to make durable, long life pavements. But no one pavement can fulfil designed purpose forever. On other hand, some natural resources are limited, so it is important maximize use renewable resources. In recent years, a visible pursuit this trend, in construction represented mostly by waste materials, such as industr...

Waste polymers are widely used in asphalt modification, especially, order to reduce their detrimental effect on the environment. This study discusses usability of waste expanded polystyrene (EPS) foam modification. In this respect, EPS foam, which produces both production and use stages, was mixed with bitumen by weight at ratios 2%, 4%, 6%, 8%, dry modification method employed. The penetration...

Despite asphalt self-healing with encapsulated rejuvenators having been intensively researched over the last decade, there is still uncertainty about performance advantages granted by this technology. As a way of adding to existing set research methodologies, study aimed test feasibility visual method investigate working mechanism in bituminous mixture. For purpose, clear mixtures were produced...

The objective of this research was to develop prediction models for complex shear modulus (G*) and phase angle (δ) bitumens modified with crumb rubber, styrene-butadiene styrene, polyphosphoric acid at low moderate temperatures. experiments consisted three different dosages each modifier added the original bitumen followed by measurement G* δ using dynamic rheometer (DSR) test in frequency swee...

Abstract In order to explore the rheological properties of high content warm mix recycled asphalt binder, was added into prepare asphalt. The optimum regenerant and Sasobit REDUX determined by basic performance test temperature scanning test. chemical composition studied FITR. low crack resistance were analyzed DSR BBR tests, determined. results show that when is 10%, its recovers level base ca...
