UNIT I HIGHWAY PLANNING AND ALIGNMENT 9
History of road construction – Highway development in India – Jayakar committee
Recomendations and realisations – Twenty year road development plans – Concepts of
on-going highways development programmes at national level – Institutions for highway
development at national level – India road congress – Highway research board, national
highway authority of India – Ministry of Road Transport and Highway (MORTH)
Central road research institute – Requirements of ideal alignment – Factors controlling
highway alignment engineering surveys for alignment – Conventional methods and
modern methods (Remote sensing, GIS and GPS techniques) – Classification and cross
section of urban and rural roads – Highway cross sectional elements – Right of way,
carriage way, camber, kerbs, shoulders and footpaths (IRC Standards) – Cross sections
of different class of roads – Principles of highway financing.
UNIT II GEOMETRIC DESIGN OF HIGHWAYS 9
Design of horizontal alignment – Horizontal curves super elevation – Widening of
pavements on horizontal curves and transition curves design of vertical alignments –
Rolling, limiting, exceptional and minimum gradients, summit and valley curves – Sight
distances – Factors affecting sight distances – PIEV theory, stopping sight distance (SSD)
– Overtaking sight distance – Sight distance at intersections – Intermediate sight distance
and illumination sight distance [Derivations and problems in SSD and OSD] – Geometric
design of hill roads [IRC Standards Only].
UNIT III FLEXIBLE AND RIGID PAVEMENTS 9
Rigid and flexible pavements – Components and their functions – Design principles of
flexible and rigid pavements – Factors affecting the design of pavements – ESWL,
climate, sub-grade soil and traffic – Design practice for flexible pavements (CBR
method, IRC Method and Recommendations – Problems) – Design practice for rigid
pavements – IRC Recommendations (concept only).
UNIT IV HIGHWAY MATERIALS AND CONSTRUCTION PRACTICE 9
Desirable properties and testing of highway materials– Soil – California bearing ratio test
– Field density test – Aggregate, crushing, abrasion, impact tests, water absorption –
Flakiness and elongation indices and stone polishing value test – Bitumen – Penetration,
ductolity, viscosity, binder content and softening point tests – Construction practice –
water bound macadam road – Bituminous road and cement concrete road (As per IRC
and MORTH specification) – Highway drainage (IRC Recommendations).
UNIT V HIGHWAY MAINTENANCE 9
Types of defects in Flexible pavements – Surface defects – Cracks, deformation,
disintegration – Symptoms – Causes and treatments – Types of pavement – Failures in
rigid pavements – Scaling, shrinkage, warping, structural cracks spalling of joints and
mud pumping – Special repairs – Pavement evaluation – Pavement surface conditions
and structural evaluation – Evaluation of pavement Failure and strengthening – Overlay
design by Benkelman Beam method (Procedure only).
