Optimization of asphalt rubber hot mixes based on

Gap-graded hot mixes were prepared using 8% of modified AR binder and resilient modulus and fatigue tests were carried out. Tests with the modified binder showed a great influence of the rubber content, digestion time and temperature in the asphalt-rubber behaviour.

Universidade do Minho: Optimization of asphalt

Asphalt binders modified with crumb rubber recycled from ground tires have been successfully used in asphalt mixtures improving the mechanical and functional behaviour of the pavements. This paper shows the influence of several factors that affect the behaviour of asphalt-rubber AR and of hot mixes made with this material.

Dense Graded Hot Mixes Using Asphalt-Rubber

This paper shows the results of a study about the mechanical behavior of dense graded asphalt-rubber hot mixes prepared with two different types of asphalt-rubber binders.
