“…Sample aging lies in the acceleration of aging in a forced air oven during different time periods. Circulation of warm air in the interior of the oven ensures that aging is produced uniformly over the sample contact surface, guaranteeing gradual and homogenous aging [5]; [7]; [8] ; [13]. The aging conditions consist in maintaining the samples at a const ant temperature of 163 °C during 0, 5, 20, 40 and 72 h respectively to obtain different degrees of aging.…”

“…The mechanisms that intervene in the aging process are associated to chemical, physical, mechanical and rheological changes to the mixture and in particular their organic component (bitumen). The aging process starts during fabrication at the factory and continues during its transfer and construction of roads, extending throughout its service life [5,8,9]. Aging that appears during road construction is known as ''short term aging" and it is more aggressive according to the aging curve by Read & Whiteoak (2003) [10].…”

The rapid development that our society is experiencing effects road management, therefore developing economical and efficient solutions, as well as extending road service life is indispensable. Aging is a problem associated to the majority of failures at the pavement surface layer (cracks, fissures, fatigue), including those produced by traffic solicitations. Diverse studies indicate that alterations to mixtures due to age can be decreased by incorporating a filler or mineral filler. Therefore, the present study incorporates cellulose ashes at different Cv/Cs concentrations as contribution filler in bituminous mastic, analysing its influence on aging resistance using the Cantabro wear test. The results indicated that using cellulose ash as contribution filler allows promising results to be obtained in regards to aging resistance of asphalt mixtures, if they are incorporated in concentrations close to or equal to the critical concentration, with an increase in aging resistance from 45.3 to 48.6% depending on the type of bitumen used. Therefore, incorporating them into the design of asphalt mixtures could be an efficient and economical solution to the current problems of early cracking and pavements with a service life lower than the estimated, although a more thorough analysis of its behaviour in other tests and service conditions is required in bituminous mixtures.

“…Several research reports dealing with the investigation of potential waste materials able to act as traditional filler materials have been presented in the literature, including fly ash and slag [24], recycled concrete powder [25], cement kiln dust [26], waste glass [27], brick powder [28], rice husk ash [29], coal waste powder [30], oil shale [31], waste bleaching clay [32], paper industry wastes [33], recycled waste lime [34], phosphate waste filler [35], municipal solid waste incineration ash [36][37][38], baghouse fines [39], oil shale fly ash [40], waste ceramic materials [41], waste marble materials [42][43][44][45], and waste tires [46,47]. It has also been reported that the properties of bituminous mastic are closely related to the type and percentage of fillers in the asphalt mix [48].…”

One important role in asphalt mixture performances is represented by the filler content and characteristics. This research aims to assess the potential usage of industrial waste powders as replacers of the standard limestone filler in asphalt mixture composition. First of all, an SEM and EDX analysis was carried out to figure whether this industrial waste can be used in asphalt mixture composition by comparing the results of the industrial wastes with the properties of the standard filler. After a chemical evaluation, laboratory investigations were carried out to characterize the materials in terms of geometrical and physical properties. The research study involved sixteen dosages of limestone filler with four different types of industrial waste powders in different percentages used. The results obtained from laboratory testing suggested that the inclusion of industrial wastes in the manufacture of asphaltic mixtures may have benefits for the construction industry, the waste management sector, and also for the environment.

“…Wahhab et al [16] blended OSA at a ratio of 2% with asphalt binder and applied in asphalt concrete mixes, which indicated that modified asphalt binder with OSA significantly improved the performances of the asphalt pavement such as split tensile strength, fatigue life, and resistance to rutting [16]. Azzam et al [17] studied hot mix asphalt mixtures containing OSA and classical limestone filler based on the Superpave design method. They measured rheological and pavement properties, and observed that hot-mix asphalt incorporating OSA possessed more excellent properties compared to hot-mix asphalt containing ordinary limestone filler [17].…”

Assessing High- and Low-Temperature Properties of Asphalt Pavements Incorporating Waste Oil Shale as an Alternative Material in Jilin Province, China

This study investigates the feasibility of recycling waste oil shale as an alternative material into asphalt pavements in Jilin province, China. The high-and low-temperature properties of asphalt materials play important roles for asphalt pavements in seasonal frozen regions. Laboratory experiments were conducted to analyze the high-and low-temperature properties of asphalt mastics and mixtures. Results indicated that adding oil shale ash (OSA) may lead asphalt to a softer consistency and less temperature susceptibility. Also, OSA could improve high-temperature stability and enhance rutting resistance of asphalt materials, whereas the effect of OSA on low-temperature properties is insignificant by comparison. Moreover, the high-and low-temperature performances of asphalt mixtures were evaluated based on testing roads through rutting depth index, riding quality index, and indirect tensile strength test. It can be proved that the sustainable asphalt materials have better high-temperature stability and rutting resistance and also fulfill the requirements of low-temperature cracking resistance.
