Abstract
The invention discloses a waste plastic cement stabilized macadam material which comprises the following components in parts by weight: 100 parts of macadam, 4.5-5.5 parts of cement, 4.5-6 parts of water and 3-5 parts of waste plastic. The invention further discloses a preparation process of the waste plastic cement stabilized macadam material. According to the waste plastic cement stabilized macadam and the preparation process thereof, the mechanical property of a cement stabilized macadam base material is improved, a new way of waste plastic is developed, and the material has good integrity, excellent shrinkage resistance and crack resistance and relatively high deformation resistance, and is suitable for being used as a cement stabilized macadam base material. All indexes and performances meet the requirements of related standards, waste plastic beverage bottles are adopted as additives of the cement stabilized macadam material, waste is turned into wealth, and the cement stabilized macadam material has double benefits of engineering and environmental protection.
Description
technical field [0001] The invention relates to the technical field of roadbed materials, more precisely, it relates to a waste plastic cement stabilized gravel and a preparation process thereof. Background technique [0002] The semi-rigid base is the main load-bearing layer of the road structure, and its good mechanical properties are the basis for realizing the "strong base and thin surface" pavement structure. Inorganic binder stabilized base material has the characteristics of good stability, strong frost resistance, and self-contained board structure, but its wear resistance is poor, so it is widely used in the base and subbase of pavement structures. Cement-stabilized gravel materials not only have the advantages of high strength, good stability, high rigidity, and good board performance, but also the raw materials are easy to obtain, which is conducive to mechanized construction, and the project cost is low, which can meet the needs of heavy traffic development. The...
