Vibration-compression-free regenerated cement stabilized macadam
The invention belongs to the technical field of regenerated cement stabilized macadam, and particularly relates to vibration-pressing-free regenerated cement stabilized macadam which comprises the following components in parts by weight: 4-5 parts of a cement material, 100 parts of regenerated aggregate and 3.5-4 parts of water, the cement material comprises regenerated cement and a vibration-compression-free additive; the vibration pressure-free additive comprises an expanding agent and trimethyl octadecyl ammonium bromide. The expanding agent added into the vibration-compression-free regenerated cement stabilized macadam can enter micropores and cracks of the regenerated aggregate, and the strength of the aggregate is improved through the expansion effect; the expanding agent existing in gaps among the regenerated aggregates can achieve a good gap filling effect, so that the compaction degree is improved under the condition of no vibration compaction, and the added trimethyl octadecyl ammonium bromide is beneficial to improving the adsorption effect of the regenerated aggregates on the expanding agent; and a long carbon chain of trimethyl octadecyl ammonium bromide can extend into micropores of the regenerated aggregate, so that the micropores of the regenerated aggregate can be filled to a certain extent, and the overall strength can be improved.
本申请属于再生水泥稳定碎石技术领域，具体涉及一种免振压再生水泥稳定碎石，包括如下重量份的各组分：水泥料4‑5份、再生集料100份、水3.5‑4份；所述水泥料包括再生水泥和免振压添加剂；所述免振压添加剂包括膨胀剂和三甲基十八烷基溴化铵。本申请的免振压再生水泥稳定碎石中添加的膨胀剂可进入再生集料的微孔和裂缝中，通过膨胀作用提高集料的强度；存在于再生集料间空隙中的膨胀剂可以起到良好的空隙填充效果，从而在不振动压实的情况下提高压实度，添加的三甲基十八烷基溴化铵有利于提高再生集料对膨胀剂的吸附效果，且三甲基十八烷基溴化铵的长碳链可以伸入再生集料的微孔中，在一定程度上对再生集料的微孔起到填补作用，有利于提高整体强度。
