Concrete Roads

Cosmetic Roads


Cosmetic Roads are specifically designed for the customer using unique workmanship. By using Road paints, Portland cement, Epoxy pigments, Steel, and other materials, we are able customize the road designs and create value for our customers.


Concrete Roads


Concrete Roads (specifically, Portland cement concrete) are created using a concrete mix of portland cement, coarse aggregate , sand and water. In virtually all modern mixes there will also be various admixtures added to increase workability, reduce the required amount of water, mitigate harmful chemical reactions and for other beneficial purposes. In many cases there will also be Portland cement substitutes added, such as flyash. This can reduce the cost of the concrete and improve its physical properties. The material is applied in a freshly mixed slurry, and worked mechanically to compact the interior and force some of the cement slurry to the surface to produce a smoother, denser surface road, free from honeycombing. The water allows the mix to combine molecularly in a chemical reaction called hydration.


Concrete Roads are refined into three common types: Jointed Plain (JPCP), Jointed Reinforced (JRCP) and Continuously Reinforced (CRCP). The one item that distinguishes each type is the jointing system used to control crack development.


Jointed Plain Concrete Pavements (JPCP) contain enough joints to control the location of all the expected shrinkage cracks. The concrete cracks at the joints and not elsewhere in the slabs. Jointed plain pavements do not contain any steel reinforcement. However, there may be smooth steel bars at transverse joints and deformed steel bars at longitudinal joints. Today, a majority Connect- Infra builds jointed plain pavements.


Jointed Reinforced Concrete Pavements (JRCP) contain steel mesh reinforcement (sometimes called distributed steel). In jointed reinforced concrete pavements, designers increase the joint spacing purposely, and include reinforcing steel to hold together intermediate cracks in each slab.


Continuously Reinforced Concrete Pavements (CRCP) do not require any transverse contraction joints. Transverse cracks are expected in the slab. CRCP pavements are designed with enough steel, so that cracks are held together tightly. Determining an appropriate spacing between the cracks is part of the design process for this type of pavement.


Continuously reinforced designs may cost slightly more than jointed reinforced or jointed plain designs due to increased quantities of steel. Often the cost of the steel is offset by the reduced cost of concrete because CRCP is nearly always significantly thinner then a JPCP designed for the same traffic loads. Properly designed JPCP and CRCP should demonstrate similar long-term performance and cost-effectiveness. Connect Infra have made policy decisions to use CRCP designs in heavy urban traffic corridors.
