Concrete Pavement Construction Trivia
Three forms of concrete pavement design are typically utilized in pavement construction: jointed plain concrete pavements (JPCP), jointed reinforced concrete pavements (JRCP), and continuously reinforced concrete pavements (CRCP) (CRCP). Each of these design options can produce long-lasting pavements that meet or exceed project specifications. Each is appropriate for new road construction, reconstruction, and overlays (resurfacing) of existing roads.
Concrete pavements provide high-quality guarantee and will continue to be more competitive in the future, especially with the state of our environment and the economy at the forefront of people’s minds. Concrete pavements are cost-effective (both in the short and long term) and are increasingly being acknowledged as the environmentally appropriate option for both new and restoration projects. They simply survive longer than flexible pavements, therefore they don’t need to be rehabilitated or rebuilt as frequently. Another factor to consider is that concrete pavements utilize far less aggregate than flexible pavements.
This helps to conserve nonrenewable resources while also reducing truck traffic and congestion. Because of the stiff structure of concrete pavement, which allows for thinner base cross sections, less dirt must be dug for a concrete road (as compared to flexible options). With the growing difficulty in finding sites to deposit any contaminated soils, this is a tremendous benefit. Longer-lasting concrete also helps to reduce traffic congestion and vehicle emissions by reducing the number of construction zones that hinder traffic flow during the pavement’s lifetime.
Concrete pavements also conserve fuel and reflect light and heat rather than absorbing it, which are two additional benefits. Fresh studies from Sweden and the United States reveal significant savings on diesel fuel for heavy trucks, while new research from Sweden and the United States demonstrate gasoline savings for cars and light vehicles. As a result of these reductions, vehicle running expenses are lower, and CO2 emissions are considerably decreased. Because concrete pavements reflect light, they can lower the cost of purchasing and operating light standards by 20 to 30 percent. Additionally, because concrete pavements reflect heat, they help to cool neighborhoods and lessen the Urban Heat Island Effect.
Every feature of concrete can be linked to a long-term advantage. For Responsible Materials Procurement, concrete pavements are a great option. The Ready Mixed Concrete Association of Ontario (RMCAO) has created the “ECO CERTIFIED Concrete Facility” certification scheme to address sustainable materials sourcing.
