Currently existing Accelerated Pavement Testing (APT) systems developed in several countries have been employed mainly to test the performance of asphalt pavement. Meanwhile, the length of concrete pavement is similar to that of asphalt pavement in expressways of Korea. and is expected to increase due to its durability and compatibility to our weather condition. To meet the society's demand of having our own APT system which can examine the long-term performance of concrete pavement, a contract study to develop Korea Accelerated Loading and Environment Simulator (KALES) for concrete pavement has been performed for 3 years from 1997 through 1999. Through the project, a detailed design was Peformed for the KALES system in which the entire structure of KALES, loading mechanism, wandering mechanism, suspension system, driving system were proposed. Also in advance to design a full-scale KALES system, a sample scale model was manufactured and tested for operating motion and force distribution. It is evident that the proposed prototype KALES system will provide higher degree of traffic simulation and durable operation, based on the satisfactory fatigue analysis.

일본포장관리사회는 93년도 일본 포장업계 10대 뉴스에서 자국 포장업계가 93년도 한 해 '미증유의 시련기' 였음을 제일 첫째로 꼽고 있다. 거품경제 붕괴 뒤의 경기 후퇴, 엔고 등 나름대로 이유가 있었겠지만 국내 포장업계 사정도 일본의 경우와 크게 다르지 않았을 것으로 사려된다. 구랍 16일 한국포장협회 회의실에서 각 부문의 관계자들이 참석한 가운데 열린 좌담회를 통해 93년도 국내 포장산업의 회고와 94년도 전망을 들어본다.
