This paper presents a study carried out to evaluate and compare the permanent deformation of marginal soils. Under consideration were marl, sabkha and dune sand stabilized with foamed and emulsified sulfur asphalt (FSA, ESA) with mixes of the same soils stabilized with conventional foamed and emulsified asphalt (FA, EA …

There is a need to improve the performance of asphalt binders to minimize stress cracking that occurs at low temperatures and plastic deformation at high temperatures. Importation of used asphalt-polymers from abroad, leads to an increase in the total construction cost as compared to the cost if the used polymers were …

Pavement weathering or stripping is a major distress in highway networks in arid regions. Using the Saudi Arabian road network as a case study area, seventeen road test sections were selected, out of which eight were stripped and nine were non-stripped. Aggregates from quarries used to build these sections were also co …
