Experimental Study On The Corrosion Resistance Of Bagasse Fiber

Our country develop with a high rate,the transportation industry which play aimportant role should have a more safetier.healther ande longer development.Therequirement about the fracture of transportation industry is that it must keep pace withthe times,especially the durability.It confirmed that the asphalt mixture has moreadvantages than other types of road through the decades studies of domestic andinternational road workers,but there is no denying that the asphalt mixture pavement hassome defect.The road worker must solve the problem,especially on the corrosionresistance of asphalt pavement.This article do some tests inculding Marshall test,immersion Marshall test andfreeze-thaw splitiing test with the ordinary asphalt mixture and the bagasse fiber with0.15%,0.25%,0.35%content in a conventional external environment.The result confirmedthat the best dosage of fiber about the bagasse fiber asphalt mixture is0.25%;when thecontent of bagasse fiber is0.25%,the residual stability is much better than others;the besteffect of the freeze-thaw splitting strength rantio of the bagasse fiber asphalt mixture is the0.15%bagasse fiber asphalt mixture.Of course,all of the result of test were consistentwith the stadard of our country.In additional,there are some tests inculding the loss of quality about the bagasse fiberasphalt mixture,immersion Marshall test and splitting strength test at doses of0.05%,0.15%,0.25%,0.35%bagasse fiber in the simulated acid rain environment.Theconclusion is that the mixture specimen wich has the best retarded function about themixture’quality loss,its fiber dasage is0.15%;the fiber dosage of0.25%of the mixturespecimen has the most excellent at the function of viod delay and the splitting strength.
