一种使用RH型WMA的沥青混凝土摊铺工艺
摘要：
本发明涉及一种使用RH型WMA的沥青混凝土摊铺工艺，它至少包括以下步骤：1）原材料准备，2）RH型WMA的沥青混合料拌和；３）混合料摊铺；４）混合料碾压；其特征是：所述的RH型WMA的沥青混合料拌和是在施工环境温度高于18℃的条件下，将RH温拌改性剂先加入沥青灌中制成温拌改性沥青，形成均匀的混合料后随时备用；在施工环境温度低于18℃的条件下，在普通沥青混合料拌和过程中直接添加RH温拌改性剂生产温拌改性沥青混合料，将沥青温拌改性过程和混合料拌和生产融为一道工序本发明的工艺克服了普通沥青混合料低温不易摊铺、不易压实的局限性，改善了摊铺和压实条件，延长了沥青混合料压实成型的时间，延长了施工季节，有效加快了施工生产进度，施工成本节约显著。
摘要（英）：

The invention relates to an asphalt concrete paving process using RH type warm mix asphalt (WMA), which at least includes the following steps: (1) preparing raw materials; (2) stirring asphalt mixture of RH type WMA; (3) paving the mixture; and (4) grinding the mixture. The asphalt concrete paving process is characterized in that stirring of the asphalt mixture of the RH type WMA is conducted under the condition that the construction environment temperature is higher than 18 DEG C, an RH warm mix modifier is first added into an asphalt tank to make warm mix modified asphalt, and even mixture is formed to be reserved at any time. Under the condition that the construction environment temperature is lower than 18 DEG C, the RH warm mix modifier is directly added in a process of common asphalt mixture stirring to produce the warm mix modified asphalt mixture, and an asphalt warm mix modifying process and mixture stirring production are integrated into one procedure. The process overcomes limit that common asphalt mixture can not be paved and compacted easily at the low temperature, improves paving and compacting conditions, prolongs compaction and molding time of the asphalt mixture, prolongs construction seasons, effectively quickens construction production progress, and remarkably saves construction cost.
