The present invention relates to a device and method for evaluating a surface photocatalyst residual amount of a road structure using a hyperspectral sensor to easily evaluate a degree of wear of the surface photocatalyst in a non-destructive method by analyzing a reflectivity characteristic of the surface photocatalyst residual amount of the road structure. By installing the hyperspectral sensor in a mobile device to calculate the reflectivity of the surface of the photocatalyst road structure for reducing fine dusts, the present invention allows for long-term monitoring of the surface photocatalyst as the non-destructive method for evaluating the amount of photocatalyst worn on the surface of the photocatalytic road structure when the photocatalyst road structure is worn from a vehicle load and an external environment, thereby allowing for economical management and maintenance to be made easy. 본 발명은 도로구조물의 표면 광촉매 잔량의 반사도 특성을 분석하여 표면 광촉매 마모 정도를 비파괴 방법으로 용이하게 평가할 수 있도록 한 초분광센서를 이용한 도로구조물의 표면 광촉매 잔량 평가 장치 및 방법에 관한 것으로, 이동장치에 초분광 센서를 설치하여 미세먼지 저감을 위한 광촉매 도로 구조물 표면의 반사도를 산출함으로써, 광촉매 도로 구조물이 차량 하중 및 외부환경으로부터 마모될 경우, 광촉매 도로 구조물 표면에서 어느 정도 양의 광촉매가 마모되었는지 평가하는 비파괴 방법으로 장기적으로 표면 광촉매를 모니터링하여 경제적인 관리 및 유지보수가 용이하도록 한 것이다.
