“DerzhdorNDI” SE specialists performed a visual and instrumental inspection of the road H-32 Pokrovsk - Bakhmut - Mykhailivka, on the road section km 16 + 00 - km 31 + 00, as the part of scientific and technical support.
The technology of rubllization of a cement concrete pavement which is based on cement concrete recycling as the foundation for arrangement of new layers of pavement is tested here.
The principle of the technology is the significant reducing of the effective length of cement concrete slab by crushing it into fragments, which minimizes horizontal movements in the expansion joints during seasonal temperature fluctuations.
After inspection performing, our specialists proposed a science-based scheme of cement concrete destruction, determined the actual modulus of elasticity and calculated the design of pavement, which meets the requirements of GBN B V.2.3-37641918-559: 2019 "Roads. Non-rigid pavement. Designing".
