Abstract

Previous studies have considered the permeability and construction method of paving materials, thus focusing on more practical issues rather than basic research of their properties. The present study investigated the possibility of using an elastic paving material having lesser thickness in the resurfacing of existing concrete or asphalt paved areas while satisfying the necessary conditions of resilience and water permeability. An alternative to complete reconstruction would reduce the amount of resource wastage and environmental pollution, as well as the cost of projects. This study investigated five variants of thickness (10, 13, 15, 20, 25mm) and three mixing ratios of binder to rubber chips (20, 22.5, 25%) to ascertain the ideal basic properties of each. The obtained test data revealed that a minimum thickness(10~25mm) of the elastic paving materials can be determined from a qualitative point of view, and alternatives should be provided to improve the durability of the paving material on account of the temperature sensitivity.

탄성포장재에 대한 기존의 연구는 포장재의 투수성, 공법적용에 관한 접근이 많아 탄성포장재의 기초적인 성능연구보다 실용화에 초점을 맞춘 연구가 많았다. 본 연구에서는 경제적인 차원에서 필요한 탄성조건과 투수성 등을 만족하면서 콘크리트나 아스팔트로 포장된 장소에서 기존 하층 노면에 대한 재시공 없이 자원낭비나 환경오염이 발생하지 않도록 두께가 얇은 탄성포장재의 시공 가능성에 대하여 두께가 다른 5종류(10, 13, 15, 20, 25mm)의 시험편과 고무 칩과 바인더의 혼합비가 다른 3개(20, 22.5, 25%)의 시험편을 가지고 다양한 시험을 실시하고 기본적인 물성을 파악하였다. 결과적으로 정성적인 관점에서 탄성바닥재의 두께를 품질조건에 따라 최소한(10~25mm)으로 할 수 있는 여지가 있으며, 바닥재가 온도에 민감하여 내구성증진에 대한 대안도 필요하다고 판단된다.
