“…Their absence in the collected 12/4/2007 sealants clearly demonstrated that despite the extended heating, the bituminous sealant in the kettle had not oxidized. This is in contrast to the oxidation of bitumen during paving operations (19), but in accordance with the results for another sealant installation (9). The results thus clearly indicate that in the kettle there is very little, if any, diffusion of oxygen within the sealant mass.…”

“…Earliest work to simulate aging in laboratory was by Dow [5] who used extended heating test. Since then, many research efforts [6,10,27,50,57,[85][86][87][88][89][90][91][92][93][94][95][96][97][98][99] have been devoted to assess effect of aging on the performance of asphalt materials. After aging acceleration treatment, samples are usually studied to quantify changes in the asphalt binder/mixture properties before and after the aging treatment (commonly known as aging index).…”

e detrimental effects of hardening in asphalt pavements were first recognized by pioneering pavement engineers in the 1900s and have been studied extensively during the last 70 years. is hardening process, referred to as asphalt aging, is generally defined as change in the rheological properties of asphalt binders/mixtures due to changes in chemical composition during construction and its service life period. Aging causes the asphalt material to stiffen and embrittle, which affects the durability and leads to a high potential for cracking. is paper presents the state of the art on asphalt and asphalt mixture aging and use of antioxidant additives to retard the aging. A picture of complex molecular structure of asphalt and its changes due to atmospheric condition and various protocols used to simulate aging in laboratory environment are also discussed. Emphasis is given on recent studies on simulation of aging of asphalt mixtures as there has been limited research on mixtures compared to the asphalt binder. Finally, this paper presents the application of antiaging techniques and its mechanism, use of various types of antioxidant additives to retard aging of asphalt and, hence, improve the performance of asphalt pavements.

“…in most cases, accelerated laboratory methods of oxidation are used. in contrast, few field studies of bitumen natural weathering have been performed (Verhasselt and Choquet, 1993;such et al, 1997;Mallick and Brown, 2004) and even fewer have studied natural oxidation by means of infrared spectroscopy (durrieu et al, 2007). in working with bituminous sealants, Hean and Partl (2004) have studied the evolution of the engineering properties of the materials after their weathering over five years in Switzerland, but they did not report on the effects of oxidation.…”
