IntroductionExpansive soil is one of the problematic soils that face many geotechnical engineers in the field (others include collapsible soil,quick clays,etc.).The problem of expansive soils was not recognized by engineers until the latter part of 1930.Expansive soil covers many areas in the world,especially the arid and semi-arid regions.(PDF) Effects of Inadequate Geotechnical Investigation on Thus,the road damaged and failure in this section may be due to seepage water that soften the subgrade of expansive clay.(a) (b) Figure 3 Sewage water disposed into the subsoil from the neighbor houses.Revised pavement designThe existence of the seepage water from the neighbor houses is a big hazard for the subgrade of expansive soils.(PDF) Geotechnical Aspects for Roads on Expansive SoilsFeb 10,2015·Geotechnical Aspects for Roads on Expansive Soils.Magdi M.E.Zumrawi.1.1 University of Khartoum,Department of Civil Engineering,Khartoum,Sudan.Abstract This paper presents some issues of
