Precast concrete pavement eliminates the need Precast concrete pavement eliminates the need for on-site cure time by using prefabricated for on-site cure time by using prefabricated concrete panels. The panels are made at a concrete panels. The panels are made at a specialized pre-casting facility ahead of time, then specialized pre-casting facility ahead of time, then hauled to the construction site and installed as hauled to the construction site and installed as needed. The result is a pavement that can be needed. The result is a pavement that can be opened to traffic almost immediately after panel opened to traffic almost immediately after panel installation, without compromising the durability installation, without compromising the durability and long-term performance of the pavementand long-term performance of the pavement

Benefits from using unreinforced concrete slabs are lower construction cost with the saving on mesh reinforcement and the potential for continuous pouring.

The contraction joints of unreinforced concrete slabs should be relatively maintenance free.

Roller-compacted concrete, or RCC, takes its name from the construction method Roller-compacted concrete, or RCC, takes its name from the construction method used to build it.

But unlike conventional concrete, it's a drier mix—stiff enough to be compacted by But unlike conventional concrete, it's a drier mix—stiff enough to be compacted by vibratory rollers. Typically, RCC is constructed without joints. It needs neither vibratory rollers. Typically, RCC is constructed without joints. It needs neither forms nor finishing, nor does it contain dowels or steel reinforcing.forms nor finishing, nor does it contain dowels or steel reinforcing.

The use of continuous reinforcement generates The use of continuous reinforcement generates the random cracks in the pavement, while the random cracks in the pavement, while obviating the need for transverse contraction joints obviating the need for transverse contraction joints that appear prone to joint-related distresses and that appear prone to joint-related distresses and failures. The cracks can be held tightly by the failures. The cracks can be held tightly by the reinforcement and should be of no concern so reinforcement and should be of no concern so long as they are uniformly spaced, maintaining the long as they are uniformly spaced, maintaining the structural integrity of the pavement. structural integrity of the pavement.
