Gradation Of Guss Asphalt Concrete Steel Bridge Deck Design And Performance Optimization

In the steel bridge deck, pouring asphalt concrete because of its good waterresistance, anti-aging and anti-fatigue ability, etc., are widely used in recent years.Pouring asphalt concrete road determines the quality of the performance of the entirebridge deck with the pros and cons, so graded asphalt concrete pouring design is todetermine the basis of the entire bridge deck pavement quality. China has a vast climaticconditions coupled with significant differences, thus requiring mastic asphalt needs tohave good high temperature stability and low temperature cracking resistance. Thepresent study the performance of asphalt mixture and abroad to pavement Guss mainlyin terms of gradation, asphalt content, asphalt characteristics and test methods. Despitesome achievements, but rarely considered from the perspective of slag powder andsuperfine their presence on the road with asphalt concrete pouring impact onperformance.In this paper, pouring asphalt concrete pavement affect the performance of thethree aspects of a series of studies by pouring asphalt concrete changes gradedcomposition analysis, slag pouring asphalt concrete mortar on the performance ofresearch and ultrafine powder, reached the following conclusions1in pink plastic thanthe same circumstances, the key to sieve through rate affect the performance of asphaltconcrete pouring large, but in this case mix asphalt mortar fluidity mainly affected bythe proportion affected.2asphalt mortar made of mastic asphalt with superior hightemperature performance of asphalt mastic asphalt production, but in the actualpreparation process requires attention to control asphalt mastic gum powder ratio. Afterlaboratory test results, recommended powder to binder ratio of3.0.3ultrafine powderin two ways with the purpose of replacement ore found using600ultra-fine powderprepared by pouring asphalt concrete pavement performance is better.
