BEHAK, Leonardo  y  PERES NUNEZ, Washington. Characterization of a material comprised of sandy soil, rice husk ash and potentially useful lime in pavements. Rev. ing. constr. [online]. 2008, vol.23, n.1, pp.34-41. ISSN 0718-5073.  http://dx.doi.org/10.4067/S0718-50732008000100004.

An investigation of characterization of a sandy soil mixture with rice husk ash (RHA) and lime is presented. Their objective was to study the physic and mechanic properties of the mixtures, trying to find an economical solution for low-volume transit pavements and to solve an environmental problem like is the deposition of the residual ash from de husk rice burning. The soil was extract in the nearness of Montevideo. A residual RHA of the husk incineration, carried out in an oven of the rice parboilization plant localized in Treinta y Tres City, was used. An analysis of the influence of different mixtures of soil with RHA and lime in the mineralogical composition by x-ray difractograms, optimum compaction parameters, CBR, unconfined compression and split tensile strength and durability is made

Palabras clave : Low-Volume Pavements; soil stabilization; rice husk ash.
