Abstract

In this study, the profiles of asphalt pavements were measured using a lightweight profiler and depths of macrotexture were analyzed based on the measured profiles. Profiles on dense graded asphalt pavement, prorous asphalt pavement, stone mastic asphalt (SMA) pavement, and base layer measured, and depth of macrotexture were calculated and analyzed. Profiles on the pavement that happened as asphalt mixture segregation were measured and depths of macrotexture were analyzed. The results showed that the depths of macrotexture of asphalt pavement were effectively calculated using the measured profiles, and the depths of macrotexture for different asphalt pavements were analyzed. The pavement areas which have asphalt mixture segregation were detected based on analysis of macrotexture depths.

본 논문에서는 경량 프로파일러를 이용한 프로파일을 측정하여 매크로 텍스쳐 크기를 산정하고 분석하였다. 밀입도, 배수성, SMA, 기층 포장에 대한 프로파일을 측정하여 포장에 사용된 골재에 의한 매크로 텍스쳐 크기를 분석하였으며, 재료분리가 일어난 지역의 프로파일을 측정하여 매크로 텍스쳐 깊이를 분석하였다. 본 연구 결과 프로파일 분석을 통하여 효과적으로 매크로 텍스쳐 크기를 산정할 수 있었으며, 아스팔트 혼합물 종류별로 텍스쳐 크기를 분석할 수 있었다. 또한, 매크로 텍스쳐 크기를 산정하여 분석함으로써 재료분리가 일어난 지역을 탐지할 수 있었다.
