"When an asphalt-concrete layer is laid, the independent laboratory takes a specimen of the surface in order to define its thickness, composition and quality. If some of the indicators do not conform to norms, the contracting organization will asphalt the road surface at its own expense," Yuri Ilyin specified.

The deputy head of the administration noted that within the framework of the concluded contracts while executing the programme "Safe roads of high quality", the independent examination exerts technical control of performance quality at all stages.

"In addition, all repaired roads are under warranty. If defects appear on the road surface, the contracting organization will have to conduct warranty repairs at its own expense. Otherwise, vindictive damages will be applied," the mayor's office press service quotes Yuri Ilyin.
