| 1 | 回收沥青瓦在热拌沥青混合料中的应用显示文摘沥青瓦回收作为沥青改性剂,可实现资源再利用,减少环境污染。对'湿法'回收沥青瓦(RAS)改性沥青性能进行SHRP试验、激光共聚焦扫描显微镜(CLSM)、高压凝胶渗透色谱(HP-GPC)和离析试验等研究,结果表明:RAS可显著改善沥青高温性能,但对沥青低温性能产生不利影响;CLSM结果表明:RAS改性沥青中蜡含量减小或消失;此外,RAS改性沥青中大分子含量(HMW)显著增加,RAS掺量越高,HMW越大。 | 刘真(编译) mostafa a.elseifi saman salari louay | 2016 | 中外公路2016，36，5： | 0 |
| 2 | Experimental evaluation of asphalt mixtures with emerging additives against cracking and moisture damage显示文摘The objective of this study was to evaluate and recommend an asphalt mixture design with emerging additive technologies that would provide superior performance against asphalt concrete(AC)stripping and cracking.To achieve this objective,a laboratory test program was developed to evaluate the use of nanomaterials(nanoclay and graphene nanoplatelet),an emerging anti-stripping agent(adhere),and warm-mix asphalt technologies(ZycoTherm,Sasobit,and EvoTherm).Two mix types were evaluated,which were a stone-matrix asphalt(SMA)and a dense-graded binder mix.In addition,the modified Lottman test(AASHTO T 283)and the indirect tensile asphalt cracking test(IDEAL-CT)test were used as performance indicators of moisture damage resistance and cracking susceptibility.Results were analyzed statistically to identify and quantify the effects of the design variables and selected additives on the performance,moisture damage resistance,and durability of asphalt mixes.Based on the cracking test results,a superior cracking resistance performance was observed with ZycoTherm,irrespective of the mix type.Adhere had the lowest average cracking indices for both mix types,which suggest that it would not perform as well as the other additives in terms of cracking resistance.Overall,SMA mixes displayed greater cracking resistance than the dense-graded mixtures,which may have been the result of the reclaimed asphalt pavement(RAP)material used in the dense-graded mix and its lower asphalt binder content.In terms of moisture resistance,both nanomaterials(graphene nanoplatelet and nanoclay)did not perform well as they did not meet the minimum required tensile strength ratio(TSR)criterion(>0.80).In addition,nanomaterials showed the lowest TSR values in both mix types suggesting that their effectiveness against moisture-induced damage may not be as good as warm-mix additives.On the other hand,warm-mix additives were expected to show enhanced performance in terms of moisture resistance as compared to the other additives evaluated in this study. | Md.Tanvir A.Sarkar Mostafa A.Elseifi | 2023 | Journal of Road Engineering2023，3，4： | 0 |
