The use of non-traditional alternatives in asphalt as substitution to virgin aggregates has been extensively spread in an attempt to shift towards sustainable road construction practices. Municipal Solid Waste Incineration Fly Ash (MSWI-FA) is amid the non-traditional materials that are used as a substitution for raw aggregates in bituminous mixtur...

Rutting is one of the significant distresses in flexible pavements. Examining the methods to decrease permanent deformation is of considerable importance to provide long service life and safe highways. The main objective of this paper is to undertake a state-of-the-art review to combine the existing work on the permanent deformation of asphalt conc...

Characteristics of dynamic modulus (|E*|) and phase angle are necessary to determine the response of bituminous mixtures. Limited regressions are available in the literature for phase angle prediction. This research focuses on the effect of using municipal solid waste incineration (MSWI) fly ash as fine aggregates substitution on the performance of...

Waste and recycled materials have been introduced in asphalt concrete mixtures as substitute for raw aggregates along with the efforts towards constructing sustainable pavements. Municipal solid waste incinerated (MSWI) fly ash is among the alternative materials that can be be used as substitute for the natural mineral filler. However, the effect o...

The use of un-conventional materials in asphalt pavements is becoming popular as DOTs in many countries started to legislate their in the paving industry. The motive behind this is to get rid of available waste while maintaining or improving the pavement performance Fly ash is among those recycled materials that can be used as a substitute for virg...

This study utilized the concept of surface free energy to assess the effect of binder aging, types of aggregate, and recycled mineral fillers on the moisture susceptibility of asphalt-aggregate systems. A total of 12 combinations of asphalt mastic and aggregates were evaluated. The surface free energy for each mastic type was determined based on co...

The concept of surface free energy was utilized to assess the effect of binder aging, mineral fillers, and aggregate type on the moisture damage resistance of asphalt concrete. A known methodology was used to quantify the dry and wet adhesive bond energies between four types of asphalt mastics and two types of aggregates. Furthermore, the effect of...

Limited research exists on the benefits of using geogrids to reinforce portland cement concrete structural and nonstructural members. Concrete pavement overlay is one application in which the use of geogrids can potentially enhance performance and in which the use of reinforcing steel bars is subject to various constraints and limitations. Prelimin...

Concrete pavement overlay is one application where the use of geogrids can potentially enhance performance. Preliminary research findings have shown that the inclusion of geogrids in Portland cement concrete leads t...

Limited research exists on the benefits of using geogrids to reinforce Portland cement concrete structural and non-structural members. Preliminary research findings have shown that the inclusion of geogrids in Portland cement concrete leads to a definitive improvement in the post-cracking behavior in terms of ductility, load capacity, and crack pro...
