  • Analysis of geological structures for road cut failures: a case study along Balangoda – Haputale main road 
    Senarathna, CSS; Godaliyadda, DP; Disanayaka, KTD; Premasiri, HMR; Abeysinghe, AMKB; Weerawarnakula, S [Conference-Full-text]
    This study is focused on the causes for the road cut failures and suggest a methodology to design road orientation to minimize cut failures considering geology of the rock present in the area. In the past few years, ...
  • Effect of physical and mineralogical properties of aggregates on quality of asphalt concrete 
    Wijayarathne, GWLW; Thavaneeshan, S; Sameera, BHAT; Sandamali, IGV; Chaminda, SP; Jayawardena, CL; Premasiri, HMR; Samaradivakara, GVI [Conference-Full-text]
    The major component of an asphalt matrix is rock aggregates usually consisting an amount greater than 95% by weight. One of the main reasons causing failure of asphalt paved roads during the expected service period of ...
  • Geochemical aspects of serpentine bodies off Embilipitiya, Sri Lanka and their effect on human health 
    Wickramasinghe, KO; Wijerathna, AVVP; Godawithana, CAP; Weerawarnakula, S; Premasiri, HMR; Abeysinghe, AMKB [Conference-Full-text]
    Serpentine is a mineral rich with Nickel, Chromium, Cobalt and Iron. Weathering of Serpentine rock can liberate such elements into the environment. Excessive exposure to such elements can damage human health by means of ...

    Lakmali, EN; Deshapriya, WGA; Jayawardene, KGIA; Raviranga, RMP; Ratnayake, NP; Premasiri, HMR; Senanayake, IP [Conference-Full-text]
    Coastal zone of Sri Lanka is key to the sustainable development of the country. However, the erosion of this coastal zone has been identified as a long term problem. Therefore, coastal sediment dynamics around the country ...
  • Soil nail wall design optimization by geotechnical applications and geophysical techniques 
    Hettiarachchi, DAI; Fernando, HRW; Nanthahoban, E; Sameer, STM; Abeysinghe, AMKB; Premasiri, HMR; Samaradivakara, GVI [Conference-Full-text]
    Soil nailing is a soil reinforcement technique which is used to stabilize slopes by insertion of slender elements, called nails. When steep slopes are to be stabilized by soil nailing, practical problems are encountered ...
