Abstract

This study proposes a non-contact volumetric measurement technique (3D-TD) using a 3D scanner for accurately determining the texture depth of grooved runway pavement surfaces. An industrial LED-based structured-light 3D scanner, combined with commercial 3D modeling software, was employed to digitize the pavement surface. The texture depth was calculated from the volumetric difference between a virtual reference plane and the reconstructed surface model. Comparative tests with the ASTM E965-15 method revealed a strong correlation (R2 = 0.9711), confirming the accuracy of the proposed approach. Field measurements conducted at Incheon International Airport, before and after rubber deposit removal, demonstrated its practical applicability. The observed texture depth variation ranged from 0.915 to 1.428 mm, highlighting the technique’s effectiveness for runway maintenance and rubber removal evaluation.

본 연구는 그루빙(grooves)이 적용된 활주로 포장 표면의 표면 거칠기 깊이(texture depth)를 정밀하게 측정하기 위해 3D 스캐너를 활용한 비접촉식 체적법(volumetric method) 기반 산정 기법(3D-TD)을 개발하였다. LED 기반 구조광 방식의 산업용 3D 스캐너와 상용 3D 모델링 소프트웨어를 사용하여 포장 표면 형상을 고정밀로 디지털화하고, 가상의 기준면과 표면 간 3차원 모델의 부피 차이를 계산하여 texture depth를 산출하였다. ASTM E965-15 체적법과의 비교 실험을 통해 제안된 기법의 높은 상관성(R2 = 0.9711)과 정밀도를 입증하였다. 또한, 인천국제공항 활주로 현장에서 고무 퇴적물 제거 전·후를 측정하여 현장 적용성을 검증하였다. 분석 결과, texture depth 변화량은 0.915–1.428 mm 범위로 나타났으며, 이를 통해 본 기법이 활주로 유지관리 및 고무 제거 효과 평가에 효과적으로 활용될 수 있음을 확인하였다.
