施工参数对橡胶沥青SAMI抗拉及抗剪性能的影响

The influence of construction parameters to rubber asphalt SAMI tensile and shear properties

指出橡胶沥青洒布量、碎石撒布量及碎石粒径等施工参数对橡胶沥青SAMI的使用性能具有重要影响,并通过室内试验研究了三个参数对橡胶沥青SAMI抗拉及抗剪性能的影响,并确定了几个参数的适宜取值,通过研究确定的橡胶沥青SAMI适宜的橡胶沥青洒布量、碎石撒布量及碎石粒径分别为2 kg/m2~2.4 kg/m2,12 kg/m2~14 kg/m2,9.5 mm^13.2 mm。

This paper pointed out that the rubber asphalt spray volume,gravel spray volume and gravel particle size and other construction parameters had important effects to the use performance of rubber asphalt SAMI,and through the indoor test researched the influence of three parameters to rubber asphalt SAMI tensile and shear parameters,and determined the adaptation value of several parameters,through the research determined the appropriate rubber asphalt spray volume,gravel spray volume and gravel particle size of rubber asphalt SAMI respectively was 2 kg / m2~2. 4 kg / m2,12 kg/m2~ 14 kg / m2,9. 5 mm ~ 13. 2 mm.
