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).

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).

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).
