Types of Rigid Pavement. Basically, rigid pavements are made of concrete and reinforcement bars. They are classified into the following types: –. Jointed plain concrete pavements (JRC) Jointed reinforced concrete pavements. Continuously reinforced concrete pavements (CRCP) Pre-stressed Concrete Pavements.
Grouted Macadam composite pavement (GMCP) is generally a composite pavement which is manufactured by preparing a highly workable fluid mortar which is specially designed with a very high early and 28 day strength (1 day - 45 MPa, 28 day - 105 MPa) by filling the flowing fluid mortar into a very open porous asphalt skeleton (25-32% Voids in Mix - VIM).
Mud pumping is recognized when the soil slurry ejects out through the joints and cracks of cement concrete pavement caused by the downward movement of the slab under the heavy wheel loads. Pumping is noticed just after the rains in cement concrete pavements that are placed on clayey soil subgrade. Mud pumping depends: So, from the …
