This research was conducted to study the possibility of using Bailey method of aggregate
gradation in designing Superpave HMA mixtures, and study its effect on rutting performance …

The application of recycled aggregates in the asphalt industry has been investigated in
recent decades. However, low percentages of these materials have practically been used in …

Different computer-operated temperature-controlled equipments are used to predict asphalt
mixture performance in laboratory at approximately similar conditions to actual in-service …

The main objective of this research is to find out the effect of deviation in the aggregate
gradients of asphalt mixtures from the Job Mix Formula (JMF) on the general mixture …

With an expanding world, the demand for extensive road networks is increasing. As natural
resources become scarce, the necessity of finding alternative resources has led to the idea …

This recommendation describes how to characterize the reclaimed asphalt through the
fragmentation test. The guidelines given hereafter are based on the results of a round robin …

Abstract Hot-Mix Asphalt (HMA) is a designed pre-mix of graded aggregates and bituminous-
based binder, hot applied on road pavements to provide a smooth and safe riding surface …

Asphalt mix designs tend to optimise the load transfer via aggregate skeletons as main
mechanism to provide rut resistance, often to the detriment of durability. Permeability, as a …

Nowadays, one of the most used additives in the modification of asphalt pavements is
styrene-butadiene-styrene (SBS) polymers. Crumb rubber (CR) obtained by waste vehicle …

ABSTRACT Asphalt Hot Mix (HMA) is mainly applied in highway construction in Iraq
because of its economic advantage and easy maintenance. Various factors impact the …
