This paper presents a correlations between the pressuremeter modulus (EPMT) and standard penetration test (SPT) N-value for glacial tills in the Greater Toronto Area (GTA). This study is based on the results of a comprehensive geotechnical investigations for the Eglinton Crosstown Light Rail Transit (LRT) Project in Toronto. This study focused primarily on the statistical correlations between SPT- N value and EPMT for glacial tills with different textures, such as silty clay, clayey silt, silty sand, sandy silt, sand and silt. The literature review shows that there is only very limited information available about correlations between EPMT and SPT N value for glacial tills. In this paper, correlations between SPT N-value and EPMT is suggested.
