    Concrete used in the construction of rigid pavements undergoes dynamic loading due to moving traffic and, thus, must have adequate mechanical and durability properties. Deterioration of concrete surfaces occurs due to various forms of wear such as erosion, abrasion and relative motion between the surface and moving traffic. One of the properties that affects the resistance of abrasion of

  • Construction of Rigid Pavement IJERT Journal

    Rigid pavements are those which posses note worthy flexural strength or flexural rigidity. In rigid pavement the stresses are not transferred from the grain to grain to the lower layers. The rigid pavements are made of Portland cement concrete either plain, reinforced or pre-stressed concrete. The plain cement concrete slabs are expected to take up about 45kg/cm2 flexural stress. The rigid

  • Highway Pavements: Design, Types, Flexible and Rigid

    Fully bonded and partially bonded overlays may be used if the existing pavement is sound or slightly cracked. Partially bonded overlays may be used if the existing pavement is ‘fairly’ to ‘moderately’ cracked. Un-bonded overlay with a 50 mm bituminous separation layer may be adopted if the slab is ‘moderately’ or ‘badly’ cracked.

    20.11.2016· RIGID PAVEMENTS??? As the name implies, rigid pavements are rigid i.e, they do not ex much under loading like flexible pavements. They are constructed using cement concrete. In this case, the load carrying capacity is mainly due to the rigidity ad high modulus of elasticity of the slab (slab action). H. M. Westergaard is considered the pioneer in providing the rational treatment of the rigid
