Method for measuring porosity of porous cement stabilized macadam

The invention provides a method for measuring the porosity of porous cement stabilized macadam, and the method comprises the following steps: taking a formed porous cement stabilized macadam test piece, maintaining the test piece in a standard maintenance room for 27-30 days, and performing measurement by adopting a vacuum plastic package method. In combination with the characteristics of the porous cement stabilized macadam, the invention provides the method for measuring the porosity of the porous cement stabilized macadam, the method can effectively measure the porosity of the porous cementstabilized macadam material in engineering practice; compared with the existing method for measuring a reference asphalt mixture, the method is accurate, convenient and rapid. 本发明提供一种多孔水泥稳定碎石空隙率的测定方法，包括：取成型的多孔水泥稳定碎石试件，将其在标准养护室中养护27～30天，然后采用真空塑封法进行测定。本发明结合多孔水泥稳定碎石自身的特性，提供了多孔水泥稳定碎石空隙率的测定方法，该方法能有效测定工程实际中多孔水泥稳定碎石类材料的空隙率，相比于现有的参照沥青混合料的测定方法，准确又方便快捷。
