本文叙述半刚性基层黑色路面加铺SAMI(沥青橡胶膜夹层)试验路的防裂效果。对比了铺筑与不铺筑SAMI以及不同厚度黑色面层的使用情况,分析了横向裂缝的形成原因。结果表明,加铺SAMI能延缓裂缝的出现,可适当减薄黑色面层的厚度。
This article describes the anti-cracking effect of the SAMI (Asphalt Rubber Membrane Sandwich) test road on a semi-rigid base black pavement. The use of paved and non-paved SAMI and different thickness of black surface were compared, and the formation of transverse cracks was analyzed. The results show that the addition of SAMI can delay the appearance of cracks and reduce the thickness of the black surface.
