The main influence factors on the long-term cracking resistance of asphaltic concrete pavement reviewed in the article. There is offered the indicator of long-term cracking resistance and calculating experimental method of minimum quantity defining of cycles of asphaltic concrete stressing till crack formation in compliance with climatic conditions and traffic load. The results of the comparative analysis of long-term cracking resistance of different asphalt concrete are advised.
Keywords: weather-climatic factors, dynamic influence, indicator of long-term cracking resistance, estimation long-term cracking resistance of different asphalt concrete
Results of technical diagnostics are given is long maintained water carrying out constructions nondestructive control methods on an example of irrigating systems of the South of Rossi. Possibility of use of devices of nondestructive control is especially noted at inspection them that allows operatively, without additional damages, to receive an objective assessment of their technical condition. When using this approach there is a possibility justification of parameters of defects and damages which it is impossible to establish at visual survey.
Keywords: the hydraulic engineering constructions which are water carrying out channels, nondestructive control methods, modeling, a technical condition.
