The cement concrete pavement is a pavement which takes cement concrete as a main material and is used as a surface layer, and is called a concrete pavement for short. Also known as rigid pavement, commonly known as white pavement, which is a high-grade pavement. The cement concrete pavement is composed of various pavements such as plain concrete, reinforced concrete, continuous reinforced concrete, prestressed concrete and the like. The materials used as the cement concrete surface layer include ordinary concrete, reinforced concrete, continuous reinforced concrete, steel fiber concrete, roller compacted concrete and the like.
The concrete for road surface is prepared from ordinary portland cement No. 425 or 525, medium sand or coarse sand and broken gravel of grade I or II. The 28-day ultimate compressive strength of the concrete is not lower than 30-40 MPa, the ultimate bending tensile strength is not lower than 4.5-5.5 MPa, and the cement consumption of each cubic meter of the concrete is 300-350 kg. The requirement of the lower layer material of the double-layer concrete pavement can be properly reduced. In order to improve the service performance of the concrete, a small amount of additives such as an early strength agent, an air entraining agent, a plasticizer, a water reducing agent or a polymer (see concrete additives) can be added.
The joint filler poured on the upper part of the joint is asphalt cement (also called asphalt mastic) prepared from asphalt, mineral powder, asbestos chips, cork chips or rubber powder according to a proper proportion. It also adopts neoprene hollow belt, plastic embedded strip or polyvinyl chloride daub as joint filling material, and its effect is good.
The cement concrete pavement is composed of a cushion layer, a base layer and a surface layer. The cushion layer is arranged on the town road with poor temperature and humidity conditions. So as to improve the service performance of the pavement structure. The base layer has enough anti-scouring capability and larger rigidity, and has strong anti-deformation capability, firmness, flatness and good integrity. The surface layer, cement concrete surface layer, should have sufficient intensity, durability, surface antiskid, wear-resisting, level.
When the cement road surface is being pour, though reduce inside space through the vibrating rod, still have the less space of certain quantity, make the concrete layer of formation each other joint strength not high, lead to current cement road surface to use the back in several years, can take place the condition that the road surface ftractures even collapses usually, make the whole life on road surface not long to later stage needs increase higher maintenance cost.
