Abstract Polystyrene injected concrete (PIC) is a type of lightweight concrete that internationally has a number of different applications, ranging from thermal insulation to shallow ground improvement (PIC Raft). Due to the lightweight character of this material, several benefits arise from its use in buildings…
Abstract The CPT is used extensively for site characterization, soil profiling, determination of groundwater conditions and the estimation of geotechnical parameters. The geotechnical parameters that can be estimated by using the CPT include bulk unit weight, shear strength and stiffness, among many others. Best practice…
Abstract In this paper, an integrated methodology is introduced for estimating the static vertical subgrade reaction modulus from CPT for shallow foundations on cohesionless soils. The proposed methodology relies on fundamental concepts of soil mechanics and foundation engineering applicable to flexible foundations. The methodology returns…
Abstract The Light Weight Deflectometer (LWD) is a portable device that measures the onsite dynamic or resilient modulus (Evd) of subgrade soils and pavements. The LWD, which has been used extensively in Europe and the United States, has become popular for assessing the stiffness of…
The vertical subgrade reaction coefficient Kv is extensively used by structural engineers for the design of shallow foundations. The value of the coefficient is usually estimated by the geotechnical engineer by three possible ways: in situ testing, laboratory testing and bibliography. In this paper a…
