Abstract

Rubber deposited during aircraft landing is known as the main cause of reducing surface friction force on wet surfaces. Thus, rubber deposits are removed at regular intervals for sae airplane landing. The high-pressure waterblast method, widely used for the removal of rubber deposits, is regarded as the main cause for the loss of surface material because in this method, water hits the surface directly at a high pressure. In this study, a rubber removal primer is developed to reduce surface damage by lowering the pressure of waterblast relatively during the removal of rubber deposits such that the deposits are removed efficiently even with a lower water pressure. To achieve this, basic materials appropriate for the primer were selected and their performance, penetration rate, and site applicability were evaluated. Based on the evaluations, the proportion of additive required for improving the performance of the basic materials was first determined. Then, the optimum mix ratio was derived through the evaluation of the effect on pavements, and the development of the rubber removal primer was completed.

항공기 착륙 시 발생하는 고무퇴적물은 젖은 노면에서의 표면 마찰력을 감소시키는 주원인으로 안전한 항공기 착륙을 위해 주기적인 제거를 실시하고 있다. 제거작업에 주로 사용되는 고압살수 방법은 고압의 물로 직접 표면을 타격함에 따라 표면 재료 유실의 원인이 되고 있다. 본 연구에서는 고무 제거시 살수 압을 상대적으로 낮추어 표면 파손을 저감시키고, 저수압에도 효율적으로 고무퇴적물을 제거할 수 있는 사전 처리제 개발을 진행하였다. 이를 위해 사전 처리제에 적합한 기초재료를 선정하여 성능 평가, 침투율 평가, 현장 적용성 평가를 진행하였다. 이를 토대로 기초재료의 성능 개선에 필요한 첨가제의 비율을 1차적으로 선정하였고, 포장 영향성 평가를 통해 최적배합을 도출하여 고무제거 사전처리제 개발을 완료하였다.
