Low-shrinkage cement stabilized macadam and preparation process thereof
The invention discloses cement stabilized macadam with low shrinkage. The cement stabilized macadam is prepared from the following raw materials in parts by weight: 1-4 parts of cement, 1-4 parts of fly ash, 2-10 parts of phosphogypsum, 50-70 parts of aggregate and 5-8 parts of water. Preferably, the cement is any one of ordinary Portland cement, Portland slag cement and Portland pozzolana cement. Based on the same inventive concept, the invention further provides a preparation process of the low-shrinkage cement stabilized macadam, and the low-shrinkage cement stabilized macadam is obtained by stirring and mixing the raw materials of the cement stabilized macadam. Based on the same inventive concept, the invention also provides an asphalt pavement which comprises a material layer paved by the low-shrinkage cement stabilized macadam or the low-shrinkage cement stabilized macadam material obtained by the preparation process. The low-shrinkage cement stabilized macadam provided by the invention has excellent resistance to drying shrinkage and temperature shrinkage.
本发明公开了一种低收缩性的水泥稳定碎石，其由以下重量份的原料组成：水泥1～4份、粉煤灰1～4份、磷石膏2～10份、集料50～70份、水5～8份。优选的，所述水泥采用普通硅酸盐水泥、矿渣硅酸盐水泥、火山灰质硅酸盐水泥中的任意一种。基于同一个发明构思，本发明还提供了一种低收缩性的水泥稳定碎石的制备工艺，将如上所述水泥稳定碎石的原料搅拌混合，即得低收缩性的水泥稳定碎石。基于同一个发明构思，本发明还提供了一种沥青路面，其包括由如上所述的低收缩性的水泥稳定碎石或者如上所述的制备工艺得到的低收缩性的水泥稳定碎石材料铺设的材料层。本发明提供的一种低收缩性的水泥稳定碎石，具有优异的抵抗干燥收缩和温度收缩的能力。
