RIGID PAVEMENT CONSTRUCTION

Purposes of transverse joint are listed below, except :

• Contraction joints and expansion joints were installed along transverse direction

• To control cracking of the slab because of contraction

• It separates a pavements according to number of lanes

• to relieve stresses

Choose three components of rigid pavement:

• Tiebars

• Dowel bars

• surface texture

• expansion joint

State type of rigid pavement as shown in a figure :

• Jointed reinforced concrete pavement (JRCP)

• Jointed plain concrete pavement (JPCP)

• Continuously reinforced concrete pavement (CRCP)

What type of rigid pavement as shown in a figure?

• ◦Continuously reinforced concrete pavement (CRCP)

• Jointed plain concrete pavement (JPCP)

• Jointed reinforced concrete pavement (JRCP)

Choose two (2) advantages of JRCP:

• Fewer joints

• Reliable design

• Less concern about random cracking

• Low maintenance

There are advantages of CRCP listed below, except:

• No transverse joints

• Long service life

• Applicable at all locations

• smooth riding

Choose two (2) disadvantages of JPCP:

• Increased joint cost

• High initial cost

• Increased joint maintenance

• Rehabilitation is difficult

Choose two (2) advantages of Flip Form Paving method in rigid pavement construction.

• High productivity

• Tight tolerance and side clearances

• Less expensive equipment and mobilization

• Smooth riding surface

Advantages of Slip Form Paving in rigid pavement construction are listed below, except:

• Better construction staging

• Uses low-slump PCC

• High productivity

• Smooth riding surface

Most often, Slip Form Paving Method are accomplished by three pieces of equipment, choose three (3) of the equipment:

• Placer / Spreader

• Roller screed

• Concrete paver

• Texturing and curing machine
