| Abstract: | Aiming at the emergency repair of the accidentally damaged airfield pavement,the experimental study on the polyurethane foam used for rapidly stabilized back filling aggregate of road bed has been made.The result shows that the polyurethane foam is used to stabilize the gravel under normal temperature,the unconfined compressive strength reaches 2.05 MPa in two hours.Besides,based on the experimental results,the finite element model of the structure of pavement is by using the ANSYS software to simulate and analyze.Both the strength and the analysis of the finite element have satisfied the requirement for the mechanics capability of roadbed. |
| Keywords: | airfield pavement polyurethane rapid stabilizing back filling aggregate |
