An Analysis of Material Performance and Application Effects for Geo-Cell Reinforcing Grassy Pavements
The reinforced grassy pavement structure is a new type of simple pavement structure,and has significant technical advantages in the construction of runways for general aviation,emergency rescue and other scenarios.In this paper,a typical geo-cell reinforcement material is selected to study its mechanical properties(tensile and compressive properties)and durability properties(aging resistance and erosion re-sistance)through laboratory tests.And the application effects are analyzed based on the field bearing ca-pacity test.The results show that the tensile strength and tensile modulus of single and two assembled geo-cells are 6.62 MPa and 1.09 MPa,respectively.The tensile modulus is 100.52 MPa and 21.27 MPa re-spectively.The compressive strength and compressive modulus of geo-cell materials are 101.09 MPa and 93.60 MPa respectively.The tensile properties of geo-cell materials affected by high temperature,low temperature and ultraviolet rays decrease to a great extent,but they still have a certain anti-aging ability.The geo-cell material is not affected by water erosion,and its tensile performance decreases after the ero-sion of deicing agent and gasoline,but there is no mass loss.Under the compaction degree of 85%,the re-silience modulus of the geo-cell strengthened grassland pavement increase by 28%,and this indicates that the geo-cell material has a certain strengthening effect on the bearing capacity of the grassy pavement.
