The land site is currently being developed for commercial and residential purposes and the maritime structures are being appraised to meet a further 60-year design life. The structures comprise a suspended concrete deck supported on driven concrete piles, which forms the basin deck structure. Within the concrete structure, a sheet pile wall retains soil from approximately +1·5 m chart datum (CD) to a historical dredged depth of around −8·0 m CD. The unique arrangement of the structure and the scant records have demanded challenging investigative engineering work to appraise the structure and determine whether remedial work is required. This paper describes the activities that were carried out to appraise the structures: desktop study, diver inspections, archive researching, preliminary structural assessments, finite-element analyses and design concept solutions.","PeriodicalId":51787,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Construction Materials","volume":"9 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2018-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74449717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents an investigation of the use of crushed glass as an aggregate replacement in a conventional dense-graded asphalt wearing course commonly used on highways in South Africa. The objective of this study was to design a dense-graded hot-mix asphalt that utilises 15% of waste crushed glass as a substitute material for sand, and to compare its performance with a conventional dense-graded mix. The mix design was based on current South African methods. The overall results indicate that the glass asphalt mix meets the South African criteria, thus the mix design is acceptable. The optimum binder content of the glass asphalt mix was 5·1%, compared with 5·0% for the conventional dense-graded asphalt mix. Further investigation of the stiffness and rutting performance characteristics indicated that the asphal...","PeriodicalId":51787,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Construction Materials","volume":"9 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2018-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82301956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, a suitable approach for testing aggregates with marginal to moderate alkali–silica reactivity has not been clearly identified. In this study, the mineralogical compositions of aggregates from five different quarries were investigated. Mortar bar expansion for these aggregates was tested as per the guidelines of both C 227 and C 1260. Although the tested aggregate sources proved non-reactive under ASTM C 227 test conditions, ASTM C 260 identified one group of aggregates as potentially reactive. Scanning electron microscopy imaging confirmed that two sources of aggregates were reactive. The compressive and flexural strength test results of aged specimens with reactive aggregates indicated that the strength reduction of those subjected to 1 month of ASTM C 260 exposure was similar to those of specimens under 6 months of ASTM C 227 exposure. Based on the experimental results, it appe...","PeriodicalId":51787,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Construction Materials","volume":"38 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2018-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90942383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
