摘要
采用室内试验,参照《公路工程无机结合料稳定材料试验规程》JTGE51-2009中的无侧限抗压强度试验方法、抗裂性能试验方法对振动搅拌提升水泥稳定碎石性能进行研究,结果表明:对于骨架密实型级配水泥稳定碎石混合料来说,振动搅拌技术可以提高其抗压强度和抗裂性能。
Using indoor tests,it refers to the unconfined compressive strength test method and the crack resistance test method in the Test Procedure for Stabilizing Materials for Inorganic Bonds in Highway Engineering(JTG E51-2009)to study the performance of vibration stirrer to improve cement stabilized macadam.The results show that for skeleton dense graded cement stabilized macadam mixture,vibration mixing technology can improve its compressive strength and crack resistance.
