What is a JRCP?
Jointed reinforced concrete pavements (JRCP) contain steel mesh reinforcement (sometimes called distributed steel). In JRCP, designers intentionally increase the joint spacing and include reinforcing steel to hold together mid-panel cracks. The spacing between transverse joints is typically 30 feet or more.
What is cementing pavement?
Portland Cement Concrete Pavement (PCCP) consists of cement, sand, aggregate (rocks) and water. There are also admixtures – materials often added to the concrete mix to alter its properties. These admixtures can do a number of things to the concrete mix.
What is jointed concrete pavement?
Jointed plain concrete pavement (JPCP). Jointed plain concrete pavement (JPCP, Figure 1) uses contraction joints to control cracking and does not use any reinforcing steel. Transverse joint spacing is selected such that temperature and moisture stresses do not produce intermediate cracking between joints.
What is reinforced concrete pavement?
Continuously Reinforced Concrete Pavement (CRCP) is constructed with steel reinforcing bars placed within the concrete along the entire length of the pavement. CRCP naturally forms tight transverse cracks to evenly transfer loads.
What are the different types of concrete pavement?
Types of Concrete Pavements
- Jointed Concrete Pavement.
- Continuously Reinforced Concrete Pavement.
- Roller Compacted Concrete Pavement.
- Concrete Overlays.
- Pre-Cast Concrete Pavement.
What are the three types of pavement?
Pavement Types
- Flexible pavements. Those which are surfaced with bituminous (or asphalt) materials. These types of pavements are called “flexible” since the total pavement structure “bends” or “deflects” due to traffic loads.
- Rigid pavements. Those which are surfaced with portland cement concrete (PCC).
What is difference between rigid pavement and flexible pavement?
Flexible pavements tend to have more layers and are therefore much thicker by default. Rigid pavements have fewer layers and are thinner than flexible pavements, which makes them susceptible to more repairs over time.
What is composite pavement?
A composite pavement is a type of pavement that utilizes both asphalt and concrete. Typically, a concrete base layer provides structural capacity while an asphalt surface layer provides a wearing surface course.
What are the types of joints in pavement?
Concrete pavement joints are commonly defined by their primary function (e.g., contraction or control joints, construction joints, isolation joints, and expansion joints). Within each of these types, they may be further described by their orientation (i.e., transverse or longitudinal).
What are the types of rigid pavement?
Rigid pavements can be classified into four types:
- Jointed plain concrete pavement (JPCP),
- Jointed reinforced concrete pavement (JRCP),
- Continuous reinforced concrete pavement (CRCP), and.
- Pre-stressed concrete pavement (PCP).
