  • Flexible Pavement versus Rigid Pavement

    Prof. Satish Chandra Ph. D. Director CSIR-Central Road Research Institute Delhi Two types of pavements are laid in India-rigid pavement and flexible pavement. In simple terms a flexible pavement can be defined as a pavement layer comprising of a mixture of aggregates and bitumen heated and mixed properly and then laid and compacted on a bed of granular layer. Raft foundation is a thick concrete slab reinforced with steel which covers the entire contact area of the structure like a thick floor. Sometimes area covered by raft may be greater than the contact area depending on the bearing capacity of the soil underneath. The reinforcing bars runs normal to each other in both top and bottom layers of steel reinforcement.

  • Pavement Manual Types of Flexible Pavements

    Section 2 Types of Flexible Pavements Anchor #i 2.1 Definition of Flexible Pavement. These pavements range in composition from true flexible pavement to semi-rigid systems (including the full-depth or perpetual design). This chapter is applicable to the design of these types of structures. One of the principal results from the Strategic Highway Research Program (SHRP) was the Superpave mix design method.The Superpave mix design method was designed to replace the Hveem and Marshall methods. The volumetric analysis common to the Hveem and Marshall methods provides the basis for the Superpave mix design method.

  • Comprehensive Design Example for Prestressed Concrete

    • The strip is assumed to be supported on rigid supports at the center of the girders. The width of the strip for different load effects is determined using the equations in S4.6.2.1. • The truck axle loads are moved laterally to produce the moment envelopes. Multiple presence factors and the dynamic load allowance are included. The The above is a wall expansion joint. This structural opening bisects not only the facade but the structural building elements as well. While accommodating movement joint materials used to fill wall expansion joints must restore the intended functions of the facade and structural building elements.
