The forecast of an emergency condition of a road asphalt
Attribute of presence tectonic faulting is the funnel-shaped object on the SSP-section. The presence of funnel-shaped object on the SSP-section is the attribute of soft ground. The load-carrying ability of a ground in the tectonic faulting zones is reduced and is decreasing during a time.
In St. Petersburg on D. Bedny street there was a failure of a road asphalt. It was supposed, that the failure was the result that the ground appeared is dim because of break of a sewer pipe.
However, as appeared, the sewer pipe in the order and is tight.
On a SSP-section constructed at realization of a profiling along street, the funnel-shaped object on the depths exceeding 100m (it is shown by turquoise color) is seen. This object is the indicator of a zone of the lowered carrying ability of a ground.
In immediate proximity to a surface, in a zone of a failure the second funnel-shaped object (it is shown by red color) is seen. This funnel-shaped object is consequence of deep object.
If the failure to fill in gravel, this measure will be time. Failures in this zone will repeat periodically.
