AB  - The dynamic response of rigid and flexible three-dimensional (3D) foundations of arbitrary shape, placed on a homogeneous or layered halfspace, which may contain a finite, longitudinally invariant structure or inhomogeneity, is determined numerically. A 2.5D coupled Integral Transform Method (ITM) - Finite Element Method (FEM) approach is used to compute the dynamic compliance at the surface of the stratified soil with inclusion, whereas 3D ITM fundamental solutions are applied in case of a homogeneous or layered subgrade. The foundation is modelled by 3D finite elements in both cases and coupled to the underlying ground by enforcing the compatibility conditions at the interface. Compliance functions at the soil foundation interface are presented and compared with existing solutions for verification as well as displacement distributions within the underlying ground are illustrated. The influence of the foundation stiffness on the total response as well as on the frequency dependent power transmission into the soil due to different load types is studied. Finally, the method is applied to evaluate the influence of a tunnel and a stiff cylindrical inclusion on the dynamic response of the foundation, thereby demonstrating the importance of taking into account the Structure-Soil-Structure-Interaction (SSSI).

AB  - Abstract. In view of increasing  social and environmental consciousness, a circular  approach  in  waste  materials  management in  order  to  convert  them  into new  secondary  resources  is becoming  more  necessary.  Given  this  context,  an interlaboratory  testing  program  (ILTP)  focusing  on  maximizing  the use  of  waste  aggregates  replacing  conventional  virgin  ones  has  been  launched  in  the  framework of the RILEM Technical Committee on “Valorisation of Waste and Secondary Materials for Roads”. Construction and demolition wastes,    recycled concrete aggregates   and steel slags were selected as waste aggregates to be investigated. A reference mixture prepared with natural virgin aggregates was al-so   considered   for   comparison   purposes.   This   paper   describes   the   results   achieved during the first steps of the ILTP concerning: i) the basic characterization of the selected marginal aggregates; ii) the Marshall mix design of different asphalt  mixtures  prepared  with  one  or  more  waste  aggregates.  Overall,  the  experimental results collected during these preliminary steps seem to confirm that the selected marginal aggregates can be considered as valid alternatives for the traditional road materials, while not jeopardizing their performance

AB  - Many researchers have proved that one of the parameters that most influence safe driving is operating speed, defined as the speed at which drivers travel on a dry road in free-flow conditions during daylight hours. This study describes a comparison between driver speed behavior on horizontal circular curves located in Serbia and on circular curves located in Italy with analogous infrastructural geometric contexts. Only curves within a two-lane rural road network in low-volume conditions without spiral transition curves were studied. Operating speed profiles were plotted, and a careful analysis was carried out to study the deceleration and acceleration motion at each selected curve. Speed measurements were conducted by using different devices: (a) for the Italian case, laser detectors were used that emit and receive a pair of laser beams perpendicular to the road's axis and record the instantaneous vehicle speed and (b) for the Serbian case, sensors were used with an application software developed in the LabVIEW programming environment, and signals were logged in a binary file for which the vehicle speed was measured on the basis of the passing time between two consecutive sensors along the curve. Tvvo types of driver behavior were found: (a) deceleration when approaching the middle of the curve and acceleration leaving it and (b) deceleration over the whole circular curve length. A t-test was performed. Statistically, no significant difference was produced from the analysis when circular curves were located in different states that reflected the same geometric, traffic, and environmental context.
