Types of Pavements There are two types of pavements based on design considerations i.e. flexible pavement and rigid pavement. Difference between flexible and rigid pavements is based on the manner in which the loads are distributed to the subgrade. Before ...

Applications of Fiber Reinforced Concrete in Pavements
There are various applications of fiber reinforced concrete and one of them is in the construction of concrete pavements. Fiber reinforced concrete (FRC) is defined as a composite material consisting of concrete reinforced with discrete randomly but uniformly dispersed short ...
Methods of Soil Stabilization for Pavements and their Quality Control
Methods of soil stabilization for pavement construction with materials such as cement, lime, lime-fly ash, asphalt and its quality control are discussed. Quality control is essential to ensure that the final product will be adequate for its intended use. It ...
LOAD-TRANSFER RESTORATION OF PAVEMENTS
New pavement joints typically exhibit good load transfer, particularly if the joints are doweled. However, repeated heavy loads can cause an elongation of the dowel sockets and result in dowel looseness and a reduction of load-transfer efficiency. As load-transfer efficiency ...
SUBSEALING JOINTED CONCRETE PAVEMENTS
Purpose of Subsealing The purpose of subsealing is to stabilize the pavement slab by the pressurized injection of a cement grout through holes drilled in the slab. The cement grout will, without raising the slab, fill the voids under it, ...
