一种超粘降噪沥青混合料及超粘降噪沥青混合料精罩面
摘要：
本发明公开了一种超粘降噪沥青混合料，包括以下组分：高粘弹改性沥青和矿质混合料；所述高粘弹改性沥青和矿质混合料的质量比为(6.8～7.6):100；所述矿质混合料包括石灰岩矿粉、辉绿岩细集料、辉绿岩粗集料和辉绿岩粗集料,所述石灰岩矿粉、辉绿岩细集料、辉绿岩粗集料和辉绿岩粗集料的质量比为（3～5）:（17～19）:（23～25）:（53～55）。发明还提供了一种超粘降噪沥青混合料精罩面。该精罩面施工快捷、方便、自动化程度高；与原铺装层能实现紧密粘结。该精罩面耐磨，抗裂、抗滑和降噪性能突出。
摘要（英）：

The invention discloses an ultra-viscous noise-reducing asphalt mixture. The ultra-viscous noise-reducing asphalt mixture comprises the following components of: highly-viscoelastic modified asphalt and mineral mixture with the mass ratio being (6.8-7.6):100, wherein the mineral mixture comprises limestone mineral powder, fine diabase aggregate, coarse diabase aggregate and coarse diabase aggregatewith the mass ratio being (3-5):(17-19):(23-25):(53-55). The invention also provides a refined cover surface for the ultra-viscous noise-reducing asphalt mixture. The refined cover surface is fast and convenient in construction and high in automation degree; close bonding with an original pavement layer can be realized; the refined cover surface is wear-resistant and has obvious properties such as cracking resistance, skid resistance and noise reduction.
