Surface compacting of soils is one of the measures applied in the practice of construction for the improvement of deformation and strength indicators of soil characteristics. Compacting is used both in creation of artificial bases in the shape of sand blankets and in quality enhancement of sand matresses for constructions as an underlying and levelling layer within road surface. For creation of surface compacting at a site various methods dependent on machines and mechanisms being used are applied: tamping, rolling, vibrocompaction. The research has been executed for evaluation of the efficiency of the indicated means of compacting. The set task was solved in laboratory conditions on physical models in a laboratory tray. In the course of the research the special laboratory tray was made, sandy soil model was chosen, with the help of additional equipment and developed original methodology a modelling of three methods of surface compacting was done, experiments on compacting of physical models with different soil dampness were executed, quantitative and qualitative assessments of surface compacting of sandy soil were given. On the bases of the conducted experiments the most efficient means of surface compacting of sandy soil was found. Recommendations for builders were given.
