Flexible roads have problems due to their lack of durability, lack of strength etc. Therefore, this research was conducted to identify the possibility of using polymermodified bitumen as a solution for those problems. The research methodology used was literature review. Plastic waste can be used to prepare polymer-modified bitumen. The applicability, cons and pros; the environmental aspect and economical aspect of the polymer-modified bitumen were identified in this research. Moreover, polymer-modified bitumen is identified as a solution for the flexible roads’ problems. Using the polymermodified bitumen in the road construction, addresses the problems of the flexible roads, by, increasing the roads’ strength, avoiding breakage, facing the environmental conditions more effectively etc. Furthermore, it brings benefits such as the roads becoming more comfortable for the passengers. The most effective way of constructing the plastic roads is the dry process, over the wet process. Preparing the plastic roads is an environmentally friendly method, if only thermoplastics such as Low Density Polythene, High Density Polythene, Polyurethane and Polythene Terephthalate are used. So, the plastics which are recycled few times, Polyvinyl Chloride and thermosetting plastics usage needs to be avoided. This method is economical, because the bitumen content used in the road construction can be reduced and in long term, although the initial cost of implementing the method is high, the maintenance cost is reduced. Sri Lanka will be benefited, if this method is implemented in the construction industry.","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114516092","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}

The concept of Big Data has been constantly scrutinised in terms of data creation, storage, retrieval, and analysis where professionals have identified its significance upon the volume, velocity and variety. Big Data provides the opportunity to gather more information in less time. Hence, analysis of Big Data can substantially enhance various disaster resilience activities such as issuing early warnings for evacuations; help emergency response personnel to identify areas that need urgent attention; coordination of disaster management activities; and to identify the most effective response methods for various situations. Therefore, Big Data is identified as a great catalyst for disaster response and, for better understanding of the damage situation and decision-making. Moreover, Big Data has the potential to improve disaster resilience by connecting people, processes, data and technology. However, it is essential to understand the type of Big Data that needs to be generated, to develop the data analysis as in necessary to help with real time responses, decision making and tracking of disaster victim. In order to accomplish the aim, a qualitative research approach was followed. This topical study marked the importance of big data in predicting human behavioral patterns during a disaster. Accordingly, the effective management of human and physical resources in habitual disaster territories was appraised through existing case studies in developed countries. Further, the research has successfully identified the challenges in employing Big Data upon its legal and technological barriers.","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130143896","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}

As a solution, Waste to Energy (WtE) concept was aroused, which transforms waste to energy in the form of electricity. Although it was a successful strategy for many of the countries, in Sri Lanka, most of the instances, WtE projects were resulted in failures due to issues provoke in the implementation. Poor stakeholder management has been one of the key contributing issues behind these failures. Hence, there is a timely need of identifying key stakeholders and their role to pledge project success. Despite the abundance of research on WtE projects, a gap in literature could be identified, when it comes to exploring stakeholders’ involvement in successful implementation of WtE projects in Sri Lanka. Thus, this study is aimed at bridging this knowledge gap. A qualitative research approach with two case studies were used in this study. A total of 12 interviews were conducted and collected data were analysed using content analysis. The empirical findings revealed that government, community, central environmental authority, engineering procurement and construction contractors, municipal council and central electricity board are the most influential stakeholders involved in the implementation of WtE projects. Although their level of contribution is varied to each other, all stakeholders along with their interests and involvement collectively thrive to assure the successful implementation of WtE projects in Sri Lanka. The knowledge generated through this research can be used by respective industry practitioners in Sri Lanka in implementing future WtE projects successfully.","PeriodicalId":206220,"journal":{"name":"Proceedings of the 8th World Construction Symposium","volume":"241 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115110800","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}
