Methodology for assessment of the composition and condition of artificial soils for sports construction
Abstract
A large number of stadiums and sports grounds have been built and are in operation in the USSR. In addition, hundreds of new sports facilities are built annually at factories, educational institutions, collective and state farms. In the process of new construction, operation, current, preventive and major repairs of stadiums and sports grounds there is a need for objective assessment of the composition and condition of artificial soils (special mixtures). At present, a subjective method is taken as a basis for the assessment of artificial soils, the reliability of which is not always correct. So far, for the quality assessment of running tracks, athletics sectors, tennis and other sports grounds their granulometric composition, physical-mechanical and water properties are not taken as a basis. The lack of objective assessment methods is explained by the undeveloped technical requirements for artificial soils. Thus, for example, the standard project of a normal sports core states: “...the coastal track should be elastic, flexible, have a constant volume, have a level surface of the top layer and good resistance to atmospheric (rain, snow, ice, wind) and mechanical influences...”. These requirements can by no means be called technical and do not allow for an objective assessment of the composition and condition of special mixtures.
