The Research On The Applicational Technology Of Fiber Seal Coat

Fiber Seal Coat is a reformation technology of Macadam Surface.Fiber Seal Coat is a new pattern construction and maintenance technology,it adopt Fiber Seal Coat vehicle to sprinkle emulsified asphaltum and fibre glass simultaneously,and then bestrew detritus to form a new consuming or stress absorbing layer after grinding.Fiber Seal Coat possess favorable economy benefit and applicational foreground resort to crack,water,lubricity,wear resistance and advanced construction craftwork,shortcut construction speed.There are not any technology prescriptions of its application area,material identity,mix design,construction craftwork,quality control in correlational criteria at present.The mix design of Fiber Seal Coat still bases on conventional experience method,its random and uncertainty character will result in reducing pavement performance of Fiber Seal Coat or wasting materials.Construction craftwork and quality control copy similar criterion.So the foundation of systemic Fiber Seal Coat criterion bears strong practical meaning toward its mix design.For more quest for application of Fiber Seal Coat in practical project,analysis and discussion are put up in the aspects of material choice,technology index,mix design, construction craftwork and quality control to provide some experiences and instructor,aiming at the problem of Fiber Seal Coat in the construction process,combining application example.Via different emulsified asphaltum and fibre dosage of structure deepness test,wet wheel consuming test,burthen wheel,track distortion and mechanics test grinding,results elicit diversification direction of each guideline,we can educe some conclusions by analysis,In the test of Fiber Seal Coat mix design,the grinding value,sand conglutinateing quantity of Fiber Seal Coat and Emulsified Asphalt or fibre value are not simple monotony increasing or degression,but the finest value.When emulsified asphaltum dosage is 1.7kg per square meter, track resistance and wear resistance of Fiber Seal Coat come to the best.When emulsified asphaltum dosage is 1.9kg per square meter and fibre dosage is 75g per square meter,the grinding value is the least.If fibre dosage is fixedness,mechanics performance enhance in various degree,but track resistance performance decline in various degree along with the increase of emulsified asphaltum dosage.If emulsified asphaltum dosage is fixedness,wear resistance performance and lubricity resistance enhance in various degree,but mechanics performance decline in various degree along with the increase of fibre dosage.In the lab and scene test structure deepness change conformably indicate in grinding prophase structure deepness decline speedily,then decline speed minish gradually,in grinding anaphase hardly decline.By analysing the lab and scene data we can educe some conclusions,Fiber Seal Coat possess preferable lubricity resistance.
