Concrete streets are low-servicing and can previous for quite some time with suitable treatment. They're also immune to oil and gas spills, generating them a great choice for high-targeted traffic spots.
The concrete mix achieves a higher density and cures after a while into a solid monolithic block.[22] Roller-compacted concrete is typically useful for concrete pavement, but has also been made use of to develop concrete dams, because the reduced cement content material causes considerably less heat for being created whilst curing than usual for conventionally positioned significant concrete pours.[citation essential]
