Lime stabilisation for earthworks: a UK perspective

Lime stabilisation is a versatile technique applied during earthworks operations. Modern soil recycling units are much more efficient at pulverising fill material and intermixing the added binder/water than machinery available 20 years ago. While supplier innovation adds flexibility to the site working method, specifications have not been sufficiently updated to permit optimal application. This review paper details the physico-chemical changes instigated through the lime-clay soil reaction, updating previous reviews. It aims to assist scientific debate, current practitioners and future specification changes. For example, the application of the minimum 24 h mellowing periods (mandatory to UK specifications) with high reactivity, quicklime powders is concluded to cause increased air voids in the compacted fill. Increased air voids are associated with reduced long-term strength and potential volume change from water ingress, which is of particular concern for sulfate swelling. Shorter mellowing periods and/or use of hydrated lime may lesson this issue; however, a 'one size fits all' approach is discouraged in preference to site-specific methodologies refined to suit the fill material and project requirements. The discussion also summarises working methods which may lower the risk of sulfate swell and defines areas requiring further practical research

Subversive Speculations: Reading Ann Petry\u27s \u3ci\u3eThe Street\u3c/i\u3e and Octavia Butler\u27s \u3ci\u3eKindred\u3c/i\u3e across the Sensory Line

Ann Petry’s The Street and Octavia Butler’s Kindred offer critical examinations of intersectional oppression through the framework of the “matrix of domination” as defined by Patricia Hill Collins. With an understanding of the key concepts of W.E.B. Du Bois’s color line and Jennifer Lynn Stoever’s sonic color line, this essay examines how each of these texts illuminate the complex grievances of existing in a society that perceives and marginalizes individuals on the basis of race and gender. Petry and Butler both use the speculative mode to position their examination, which not only offers a visceral portrait of this constrained identity as exemplified by the female protagonists at separate points in time, but also encourages a consideration of an alternative societal construction that is void of such assaultive hierarchy. As a result, Petry and Butler’s parallel utilization of the speculative creates a bridge for the reader to actively interact with the text on multiple levels by acting as voyeur, sympathizer, and speculator
