Bonding Characteristics Analysis of Ultra-Thin Overlay of Asphalt Pavement Layer

Abstract:

It researches ulter-thin overlays and bonding characteristics of the original road with a large number of laboratory test simulation tools in the thesis. From different spread quantities and different temperature of the adhesive layer shear strength test, you can get the layers of oil content should not be less than 2.5% of SBS modifier, the emulsified asphalt solid content should not be less than 60%. Through factor analysis of sticky layer of oil spread quantities, you can get the ultra-thin overlay layer with voids in asphalt mixtures VV and significant influence of the original pavement structure depth TD on interlayer bonding properties, the design range of appropriate void UTFC10 ultra-thin overlay is 8 ~ 12 %, the range of oil spread quantities of sticky layer is 0.8 ~ 1.2 L/m².
