摘　　要：在用机场飞行区的水泥混凝土道面表层病害普遍存在,尤为突出的是道面起砂、粗骨料裸露、麻面等。该病害加速了道面劣化,促使道面损坏情况更为严重,已经对飞机部件形成损伤并危及飞行安全。通过检测固化剂的性能并检验该工艺在停机坪和跑道上应用后的性能得知:固化剂对新混凝土表面具有一定的防护作用,打磨后道面的抗滑性能降低明显,在已起砂道面上喷涂固化剂对道面起砂病害的治理效果非常有限,建议采用更为有效的去除病害层的方法,同时也针对现行规范提出修订建议。The surface diseases of cement concrete pavement in airfield are common,especially the sand rising,coarse aggregate exposed and pockmarked surface.The disease accelerates the deterioration of the plane surface and makes the damage of the plane surface more serious,which has caused damage to aircraft parts and endangers flight safety.Through testing the performance of curing agent and the anti-skid performance of grinding process applied on the apron,it is found that curing agent has a certain protective effect on the surface of new concrete,and the anti-skid performance of the pavement decreases obviously after grinding.Spraying curing agent on the surface of sand-raising road has a very limited treatment effect on sand-raising disease.It is suggested to adopt a more effective method to remove the disease layer.At the same time,it is suggested to revise the current code.
