Transportation Engineering- I
Paper Code :CE- 602
Introduction to Highway Engineering:
Scope of highway engineering; Jayakar Committee Report; saturation system; highway financing (‘pay as
you go method and credit financing method) and highway economics (quantifiable and non quantifiable
benefits to highway users, cost of vehicle operation, annual cost method, and benefit-cost ratio method)
Highway Alignment:
Requirements; factors controlling alignment; engineering surveys for highway alignment and location.
Highway Geometric Design:
Cross-sectional elements (friction, unevenness, light reflecting characteristics, camber, kerbs, shoulders,
footpaths, width of carriageway, formation, and right of way); PIEV theory, geometric design elements like design speed, passing and non-passing sight distances; requirements and design principles of horizontal
alignment including radius of curvature, super elevation, extra-widening, design of transition curves, curve
resistance and grade compensation and vertical alignment.
Pavement design:
Evaluation of soil subgrade, sub-base, base and wearing courses; design factors for pavement thickness (including design wheel load and ESWL, strength of pavement materials and plate load tests, and effect of climatic variations) Group Index and CBR, IRC method of flexible pavement design; Westergaards analysis of wheel load stresses in rigid pavements; frictional stresses and warping stresses; IRC recommendations for design of rigid pavements; design of expansion and contraction joints. Benkelmen Beam Test .
Pavement construction Technique:
Types of pavement; construction of earth roads, gravel roads, WBM, bitumen and cement concrete roads;
joints in cement concrete pavements.
Road Materials and Testing : Soil, Stone Aggregate, Bitumen, Marshal Stability Test .
