Cement concrete pavement and asphalt pavement are most often used pavement method in bridge structures. Cement concrete pavement has advantages like less expensive, wear-resisting, suitable for high-traffic bridge, environmental sustainability, durability, and requires less repair and maintenance over time, but requires longer curing time.
Before Specifying Smoothness (1978-1983): Mean Serviceability Index = 3.9 After Specifying Smoothness (1984-1987): Mean Serviceability Index = 4.7 Considering the results from the NCHRP study (refer ence 3) mentioned previously, Wisconsin may expect an extension in pavement life of well over 15% as a result of their use of smoothness …
Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and harden into the durable material with which we are all familiar. Following is a group of ...
Concrete Technology - Concrete is a construction material composed of cement, fine aggregates (sand) and coarse aggregates mixed with water which hardens with time. Portland cement is the commonly used type of cement for production of concrete. Concrete technology deals with study of properties of concrete and its practical applications.

Plain and reinforced portland cement concrete pavements will be measured and paid for at the Contract unit price per square yard for the pertinent Portland Cement Concrete Pavement item. The square yard measurement will be computed on the basis of plan width and as-built length measured along the pavement center line.
Reducing the carbon impact of concrete is becoming an important factor in construction material choice. Slag cement is a recovered material from the iron production process and because of this, reduces the environmental impact of concrete mixtures by decreasing carbon footprint, embodied energy and the use of non-renewable materials.
