The properties of RCA were compared with state road authority requirements to assess its performance as a pavement sub-base material. The experimental programme included tests such as particle size distribution, modified Proctor compaction, particle density, water absorption, California bearing ratio (CBR), Los Angeles abrasion loss, pH, organic content, static triaxial, and repeated load triaxial tests. The Los Angeles abrasion loss tests indicated that the RCA is durable. CBR values were found to satisfy the local state road authority requirements for sub-base material. Repeated load triaxial tests established that the RCA would perform satisfactorily as a pavement sub-base material in the field. The results of the laboratory testing undertaken in this research indicated that RCA satisfied the criteria for use in pavement sub-base applications.<\/jats:p>","DOI":"10.1520\/gtj103402","type":"journal-article","created":{"date-parts":[[2012,8,9]],"date-time":"2012-08-09T16:35:47Z","timestamp":1344530147000},"page":"743-751","update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":115,"title":["Geotechnical Properties of Recycled Concrete Aggregate in Pavement Sub-Base Applications"],"prefix":"10.1520","volume":"35","author":[{"given":"A.","family":"Arulrajah","sequence":"first","affiliation":[{"name":"Faculty of Engineering and Industrial Science (H38), Swinburne Univ. of Technology 1 Associate Professor , P.O Box 218, Hawthorn VIC 3122, Melbourne, AU"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Piratheepan","sequence":"additional","affiliation":[{"name":"Swinburne Univ. of Technology 2 Lecturer , , Melbourne, AU ."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
