What is PCCP pavement?
DESCRIPTION. PCCP is composed of Portland cement concrete and, when specified, reinforcing steel and various joint materials. Concrete pavement is placed at the thickness specified in the plans or proposal and is constructed on a prepared subgrade or base course.
What is bituminous concrete?
BITUMINOUS CONCRETE means a mixture of petroleum by-products and gravel used for paving to form a smooth, permanent surface. It does not mean “oil and chip”.
Can concrete pavement be milled?
Concrete milling is a process that strips layers of concrete from roads, bridges, parking lots, and other paved surfaces to create a smooth surface with plenty of grip. A lot of equipment is involved in the concrete milling process, from the initial work to maintenance jobs.
What is rigid concrete pavement?
A rigid pavement is constructed from cement concrete or reinforced concrete slabs. Grouted concrete roads are in the category of semi-rigid pavements. The design of rigid pavement is based on providing a structural cement concrete slab of sufficient strength to resists the loads from traffic.
What is the standard thickness of concrete road?
280 millimeters
To address the early deterioration of roads due to damaging effects of overloading, the Department of Public Works and Highways (DPWH) prescribed the use of concrete pavement with minimum thickness of 280 millimeters and with steel dowels in all transverse joints.
What is a PCC slab?
Portland cement concrete (PCC) pavements (or rigid pavements) consist of a PCC slab that is usually supported by a granular or stabilized base, and a subbase. In some cases the PCC slab may be overlaid with a layer of asphalt concrete.
What is rigid pavement?
Rigid pavements are constructed of portland cement concrete slabs resting on a prepared subbase of granular material or directly on a granular subgrade. Load is transmitted through the slabs to the underlying subgrade by flexure of the slabs.

What is the difference between concrete and Portland cement?
Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete, just as stainless is a type of steel and sterling a type of silver. Therefore, there is no such thing as a cement sidewalk, or a cement mixer; the proper terms are concrete sidewalk and concrete mixer.
Why is bituminous concrete used?
Bituminous concrete is a type of construction material used for paving roads, driveways, and parking lots. It’s made from a blend of stone and other forms of aggregate materials joined together by a binding agent. Some manufacturers add recycled tires to asphalt to increase its strength and resilience.
What is bitumen used for?
Bituminous materials are used for road construction, roofing, waterproofing, and other applications. For the main application, which is road construction, the major concerns, as with concrete, are cost and durability.
What is rigid PCC pavement?
PCC Pavement Rigid pavements are so named because the pavement structure deflects very little under loading due to the high modulus of elasticity of their surface course. A rigid pavement structure is typically composed of a PCC surface course built on top of either (1) the subgrade or (2) an underlying base course.
What is the difference between PCC and lean concrete?
Lean concrete (see Figure 6). Contains less portland cement paste than a typical PCC and is stronger than a stabilized aggregate. Lean concrete bases (LCBs) can be built to as much as 25 – 50 percent of the surface course strength (FHWA, 1999).
What is rigid pavement made of?
Almost all rigid pavement is made with Portland Cement Concrete (PCC). Rigid pavements are differentiated into three major categories by their means of crack control: This is the most common type of rigid pavement. JPCP controls cracks by dividing the pavement up into individual slabs separated by contraction joints.
What is the thickness of a PCC surface?
The surface course can vary in thickness but is usually between 150 mm (6 inches) (for light loading) and 300 mm (12 inches) (for heavy loads and high traffic). Figure 4 shows a 300 mm (12 inch) surface course. Figure 3. PCC Surface
