Plain Concrete – Short Pavement Slabs This Type Of Pavement Consists Of Successive Slabs Whose Length Is Limited To About 25 Times The Slab Thickness. At Present It Is Recommended That The Paving Slabs Not Be Made Longer Than 5 M, Even If The Joints Have Dowels To Transfer The Loads. The Movements As A Result Of Fluctuations In Temperature And Humidity Are Concentrated In The Joints. Normally, These Joints Are Sealed To Prevent Water From Penetrating The Road Structure. The Width Of The Pavement Slabs Is Limited To A Maximum Of 4.5 Meter. II- Reinforced Concrete Ii-a Continuously Reinforced Concrete Continuously Reinforced Concrete Pavements Are Characterized By The Absence Of Transverse Joints And Are Equipped With Longitudinal Steel Reinforcement. The Diameter Of The Reinforcing Bars Is Calculated In Such A Way That Cracking Can Be Controlled And That The Cracks Are Uniformly Distributed (Spacing At 1 To 3 M). The Crackwidth Has To Remain Very Small, I.E. Less Than 0.3 Mm. Ii-b Reinforced Pavement Slabs Reinforced Concrete Pavement Slabs Are Almost Never Used, Except For Inside Or Outside Industrial Floors That Are Subjected To Large Loads Or If The Number Of Contraction Joints Has To Be Limited. Ii-c Steel Fibre Concrete The Use Of Steel Fibre Concrete Pavements Is Mainly Limited To Industrial Floors. However, In That Sector They Are Used Intensively. For Road Pavements Steel Fibre Concrete Can Be Used For Thin Or Very Thin Paving Slabs Or For Very Specific Applications.
