Abstract

Sivakumar et al. (2015) present an excellent experimental study that represents a major advance on efforts to get PL100 (Stone and Phan, 1995), termed the plastic strength limit by Haigh et al. (2013), into mainstream use. Given the current efforts underway to revise European soil testing standards (e.g. Orr, 2015), the paper by Sivakumar et al. is a welcome addition to the literature. Many authors have attempted to develop methods of determining the plastic limit using the cone penetrometer (e.g. Harison, 1988), as the thread rolling test is regarded by some as crude and inaccurate (e.g. Sherwood, 1970; Whyte, 1982). Sivakumar et al. offer a mechanical alternative to the original test descr..
