연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

본 연구는 고가(약 40억원)의 대형[51m(1set/3대)2차선도로 이상적용] 수입설비에 의존하는 현장 재생 아스콘 생산 설비를 국내 독자적인 기술로 설비를 직접 제작하여 수입설비 대비 소형화[19m(1set /1대) 2차선 이하 적용] 및 낮은 가격(5~10억원)으로 단점을 보완한 장비를 개발하였다. 또한 설비로 생산한 혼합물 시험을 공인기관에 의뢰하여 품질을 입증하였다

- Production costs (cost reduction rate : about 30% reduction)
: Simplify the producting process and the event of occurrence recycle ascon , 100% re-use in the field.
(Lung asphalt without factory transportation costs of the event, without re-transportation costs in the construction site from the production plant)
: Fuel, reduction of power consumption
- Patent applications of development facility

Patent applications status of development facility
1. 2016-0001760 : Transferable ascon and thereof manufacturing system and method and paving method using the same (2016.01.06)
2. 2016-0001744 : System and method for regenerating ascon and asphalt mixture using the same andmethod for paving road using the same (2016.01.06)

(2) The results of the development of medium and low-temperature asphalt additive
- Asphalt aging prevention and improvement of product quality (Performance comparison)
: Medium temperature recycled asphalt mixture used to develop medium and low temperature asphalt additive material, conventional heating recycled asphalt mixture compared to 30~50 ℃ low temperature in the heating production already, it is possible to prevent the premature aging of the asphalt, medium and low temperature (100~130 ℃) But, in comparison with the existing reproduction heating asphalt mixture, there is a thing that was verified already excellent quality performance, test results summary table below, in has been developed and low-temperature asphalt additive the production facilities of the site recycled asphalt (FR-APS) low-temperature asphalt mixture in which is manufactured by applying to the (new material, playing) with the existing stationary plant and asphalt mixture, which was produced in the production facilities of the existing site (HMA ) as a result of the comparison test, to confirm the superior quality performance.

Result tabulation of quality performance verification test
-Common verification of med-low temperature asphalt additive (Accelerated Pavement Testing, APT)
: For verification of commonality in has been developed and low-temperature asphalt additive, through production facilities on-site recycled asphalt packaging accelerated test a mixture prepared by applying to (FR-APS) (APT), of commonality We were able to confirm the performance superiority in the verification results, and low-temperature asphalt additive.

comparison graph of the amount of generation of material-specific average plastic deformation (313,000 ESALs)
- Reducing fuel costs and low-carbon(reducing carbon emissions) product ascon environmentally friendly
: Ascon environmentally friendly using medium-low temperature asphalt additive that has been developed, the results of the existing compared to the hot asphalt mixture fuel costs about 35% of the reduction and harmful gas emissionsis about 33.3% (carbon dioxide) reduction

Comparison of raw materials and emissions harmful amount of gas generated during the asphalt mixture 1 ton production
