关于改性沥青的几点看法

关于改性沥青的几点看法(,111000)(,110012)改性沥青优良的高温稳定性低温抗开裂性能与沥青组分改性剂的结构有直接关系,通过对沥青成分调整可达到提高改性沥青性能的目的,同时稳定剂的加入,可有效的改善改性沥青稳定性SBS改性沥青稳定剂(SBS,EVA,SBR),,,,,,,,20009SMA,2001),,2003)))800,,,SBS11.1基质沥青,,,,,,,,;,,,,,1.2SBS改性剂SBS,))(StyreneButadienestyreneblockpolymer),,SBS,,SBSSBS(PS)(PB),PB,PS,,SBS8~12,14~30,,,,SBS,S/B,,SBS,Tg1()Tg2(),1SBSSBS1301SBS1401SBS4303SBS4402SBS4452Tg1-90-90-89-86-83.5Tg184829494771.3质量标准56JIJ036)1998SBS(I)22.1改性沥青的制备90#,SBS,SBS#10#20045Lm,2.2实验测试(1),,2213017914303801S/B3/73/73/73/74%4%4%4%e5556696825e616765625e5cm/min38423435,e2.01.720252,,SBSSBS5e,,2.5,(2),,0.4%,334303801S/B3/73/74%4%e737425e62635e5cm/min3538,e1.71.53,,,(3)/0,,42%44303801S/B3/73/74%4%e687025e68675e5cm/min4548,e14164,,,SBS,,3),(),,,,,,,SBSSBSSBS-42002,SBS,,,:5PI-0.140-0.2T80053.6)T1.2-17.3)R0.997),5e,5cm/min(cm)48.1\45(e)74.1\70,135e(Pa.s)1.540[3(e)310\230(%)99.9\99,(%)0.7[2.5,25e(%)98\85,15e(g/cm3)))RTFOT(%)0.08[1.025e(%)79.0\60,5e(cm)38.0\205a.SBS,b.,c.SBS,(下转第13页)#11#4:,,,,,,:(1):¹;º;»;¼;½;¾;¿;À;Á0.075mm;Â;lv;lw;lx()(2):¹;º;»(3):¹;º;»;¼,,,,56(JTJ032)94),10~20e,2~5mm,,,,,,ModifiedAsphaltandMixtureDetectingIndexsAbstractAfterdiscussiaythedetectinginderonwodifiedasphaltandmixturetheauthorindicatestheim-portanceorsignificancesofdetectingindexonmodifiedasphaltandmixtureinconstruction.Keywordsmodifiedasphaltmodifiedasphaltmixturedetecting(上接第5页),10~15cm,,,10~15cm,,QualityControlonMixingAsphaltMixtureandConstructionTechniqueofAsphaltConcretePavementAbstractThispapersimplyspecifiedqualitycontrolonmixingasphaltmixtureandconstructiontechniqueofasphaltconcretepavement.Keywordscombinitiondesignqualitycontrolpavingrollingjointtreatment(上接第11页)AboutModifiedAsphaltAbstractGoodhightemperaturestabilityperformanceandlowtemperatureperformanceofmodifiedas-phalthavedirectrelationswithasphaltcomponentsandmodifierstructure.Adjustingasphaltcomponentscanim-provemodifiedasphaltperformance,andmixingstabilizercanincreasemodifiedasphaltstabilizer.KeywordsSBSmodifiedasphaltstabilizer#13#4:
