How to Test and Check the Quality of Tar used in Road Construction?

The following tests are conducted on tar to check or assess its suitability or quality for specific uses in road construction: 1. Specific Gravity: For determining the specific gravity of tar, the same procedure as for bitumen using a pyknometer is applicable. 2. Distillates: A distillation flask of about one litre capacity is filled with a weighed quantity of tar [...]

Highway Pavement: Layers, Functions, Types, Defects, Rigid and Flexible Pavements

Highway Pavement: Layers, Functions, Types, Defects, Rigid and Flexible Pavements! Pavement design, in general, consists of determining the thickness of the pavement or of the several layers of which it is composed in order to resist the wheel loads of the traffic and transmit them safely on to the foundation soil. Thus, the strength of the pavement must be adequate [...]

How to Design Rigid Pavements? | Highway | Transportation Engineering

The design of rigid pavements involves the design of the thickness of the cement concrete slab comprising the rigid pavement, since the pavement derives its structural strength primarily through the flexural strength of the slab. Except for low traffic volumes and street roads, reinforced cement concrete (RCC) slabs are used as rigid pavements. In addition to the design of thickness, [...]

How to Design Flexible Pavements: Top 4 Methods |Transportation Engineering

Design of pavements has been based on experience and judgment in the past. But the design methodology has taken rapid strides towards rationality in the past few decades based on an understanding of the stresses and strains in the layers constituting the pavement and application of the concept of reliability in achieving the desired level of service during the pavement's [...]

Transportation Planning: Process and Top 5 stages of Transportation Planning

Transportation planning is a complex problem. Increased facilities will change the environment and land use patterns and result in increased trips invalidating the original criteria and projections used. Increased use of operations research and systems approach to transportation planning in recent times seeks to optimise the system performance for deriving maximum benefit from the facilities. The use of mathematical models [...]
