Research ArticleOpen accessIn the keywordsBonding Property of Bituminous Crack Sealants in the Presence of WaterEllie Fini, Taher Abu-LebdehProblem statement: Crack sealing and filling is the most widely used maintenance activity for in-service pavements. If an appropriate sealant material is selected and properly installed at the appropriate time of the pavement life, it retards pavement deterioration and increases its service life at a relatively low cost. However, in some cases it is reported that sealants failed prematurely, mainly … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 12 Mar 2011 · 8,338 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUse of Surface Energy to evaluate Adhesion of Bituminous Crack Sealants to AggregatesEllie H. Fini, Imad L. Al-Qadi, Taher Abu-Lebdeh, Jean-Francois MassonProblem statement: The performance of bituminous sealants in the field is partly controlled by properties and strength of the sealant-aggregate interface. The thermodynamic work of adhesion represents energy required for reversible separation of the two materials at the interface. The study of fracture includes the energy required for both reversible and irreversible processes during separation. Excess of work of facture … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 7,884 accessesView PDF Cite
