Investigating the influence of mineral fillers at Australian asphalt mixtures

It is commonly known that mineral fillers significantly affect the asphalt mixture's performance. Superior flexible pavement performance can be ensured by gaining a deeper understanding of the function of filler. This research investigates the influence of three different fillers: granite dust, cement, and hydrated lime, at Australian asphalt mixtures. The testing program includes Marshall testing, moisture damage resistance, indirect tensile strength (ITS), and indirect tensile stiffness modulus (ITSM) tests of asphalt mixtures. Analysis of variance (ANOVA) was used to statistically assess the results obtained, besides damage analysis. The results indicate that using natural granite dust yields the highest resistance to moisture, while cement produces the highest stability, ITS, and ITSM. Unexpectedly, using hydrated lime filler decreases the stability/stiffness and moisture resistance of asphalt mixtures. ANOVA tests indicate that the type of filler affects ITS, TSR, and ITSM results (i.e., the p-value <0.05). The damage analysis shows that the design life of the asphalt mixture made with cement filler is higher than that of mixtures made with natural granite dust and hydrated lime fillers respectively. The findings indicate the important role of nontraditional fillers at the performance of Australian asphalt mixtures

Investigating Iraqi EFL College Students’ Ability of Parametric Resetting

This paper tries to answer whether Iraqi EFL college students are able to reset the parametric values of their native Arabic into those which suit English. It aims at enhancing Iraqi students' knowledge of some of the parametric values of English via tackling three parameters: Null-subject parameter, Head-parameter, and Serial parameter. To achieve the aim of this study,  Grammaticality Judgment Tasks are administered to sixty students of the fourth year at the Department of English- College of Languages/ University of Baghdad for the academic year 2016-2017. The students' responses have been corrected and statically analysed. The study concludes that Iraqi EFL students' ability to reset parameters varies as to the parameter in question since they have succeeded to reset the Head parameter, but failed to reset the Serial parameter; this is accompanied by a partial ability to rest the Null-subject parameter. As well, it has further been revealed that Iraqi EFL students' inability to reset a parameter is due to negative transfer from Arabic to English, hence EFL learners need be exposed to extensive input data to encourage the resetting of parameters
