WORKS QUALITY CONTROL WHEN REPAIRING ASPHALT CONCRETE PAVEMENTS WITH CEMENT CONCRETE
Abstract
The oil resources depletion possibility in the near future casts doubt on the asphalt concrete using as the main material for road surfaces. Due to this, the question arises not only about the new transport routes construction prospects, but also about the possibilities of repairing already existing flexible road pavements. Cement concrete using is the most expedient method in this case.
Although there are technology guidelines in Russia, which in theory describe the basic principles of the "whitetopping", quality control of this repairing pavements method need to be developed. The authors analyzed domestic regulatory documents and foreign sources. The methods of laying and the technology of repairing asphalt concrete with cement concrete, quality control methods, including new parameters specific to this technology, were considered.
As a conclusion, the rational thickness of the reinforcement layers, the strength class of the cement concrete used, the rationality of the use of fiber in the mixture are proposed.
