Concrete Road Construction & Paving: Step-by-Step Process #Construction #Concrete #RoadWork #CivilEngineering This video explains the full workflow of rigid pavement construction, emphasizing durability, ride quality, and long-term performance. Subgrade & base preparation: * Compaction to required density and moisture control * Placement of granular sub-base or DLC (dry lean concrete) for uniform support Formwork / Slipform paving: * Fixed forms or slipform paver used to control line, level, and thickness * Dowel bars at transverse joints and tie bars at longitudinal joints for load transfer Concrete production & placement: * Controlled mix design (low w/c ratio, suitable slump) * Continuous placement to avoid cold joints; proper distribution ahead of paver Compaction & finishing: * Internal/external vibration for full consolidation * Screeding, bull floating, and surface texturing (broom/tining) for skid resistance Jointing: * Saw-cut contraction joints at specified spacing to control cracking * Proper sealing to prevent water ingress Curing: * Immediate curing (membrane compound or wet curing) to limit shrinkage and ensure strength gain Quality control: * Thickness checks, surface evenness (IRI), compressive/flexural strength tests Executed correctly, concrete pavements deliver high load capacity, low maintenance, and long service life, especially for highways and heavy-duty roads. #ConcreteRoad #PavementEngineering #SlipformPaving #RoadConstruction #Infrastructure #CivilEngineering
