Author:Sanders, PJ; De Beer, Morris; du Plessis, HWDate:26 May 2009Various aspects of the determinations and use of elastic moduli of pavements materials are herein addressed. Included is an investigation into the sensitivity of pavement life to changes in elastic material parameters, an update of moduli ...Read more
Author:De Beer, MorrisDate:1992This paper summarises some of the main effects of non-linear, ie stress stiffening (in this case) behaviour of resilient elastic moduli of typical granular base pavement structures on the calculated deflection basin. The basin was characterized ...Read more
Author:Maina, JW; Ozawa, Y; Matsui, KDate:Jul 2008Each layer in a pavement structure is compacted during construction. Moreover, since the compaction process is carried along the same direction, it is well known that horizontal and vertical mechanical properties in each layer differ. But ...Read more
Author:De Beer, Morris; Maina, J; Van Rensburg, Yvette; Fisher, ColinDate:May 2018Mechanistic design and construction of flexible pavements with relatively thin (< 50 mm) asphalt road surfacings still remain an art today and are aimed especially towards first-class user experiences. Risks for surfacing failures are difficult ...Read more
Author:De Beer, Morris; Maina, JW; Netterberg, FDate:Apr 2012This paper (Part 2 of a two-part set of papers) discusses models and illustrates the adverse effects of weak layers, interlayers, laminations and/or weak interfaces in flexible and semi-flexible pavements, also incorporating lightly cemented ...Read more
