道面刻槽时机的科学选择

Scientific Choice of Timing of Road Surface Grooving

大型的民航运输机对飞机的制动及着陆有较高的要求,道面混凝土刻槽施工能有效增大道面的排水效率,为选择一个科学合理的刻槽时间,通过海口项目用现场实际施工分析不同强度下进行刻槽的效率及质量,发现道面混凝土强度达到6 MPa左右时施工能有效提高刻槽的效率及质量,保证飞机跑道的排水能力,使飞机在降雨时能够平稳起降。

Large-scale civil aviation transport aircraft have higher requirements for braking and landing of aircraft.Pavement concrete grooving construction can effectively increase drainage efficiency of pavement.In order to effectively select a scientific and reasonable grooving time,Haikou project demonstrates the efficiency and quality of grooving under different strengths by on-site actual construction.It is found that when the pavement concrete strength reaches about 6 MPa,the grooving efficiency and quality can be effectively improved,and the drainage capacity of the airstrip can be ensured,so that the aircraft can take off and land smoothly during rainfall.
