Macadam road Construction
33
pioneer of modern road construction
John Macadam (1756-1836)
34
250 mm layers of well compacted broken angular stones would provide the same strength and stiffness and a better running surface than an expensive pavement founded on large stone blocks

35
uses bituminous concrete and cement concrete
modern roads
36
______ distance road is constructed in Nepal
70,000 km
37
land use transportation cycle
increased accessibility increased land value changed land value increased trip generation greater traffic needs added transportation facilities
38
requires a continuous planning to optimally satisfy the mobility requirement of the society
transportation system
39
types of planning

40
less complex and put no great demand on construction activities and require less capital expenditure; includes Transportation System Management (TSM)
short term and medium term planning
41
complex problem and requires huge financial expenditure and involves large and extensive construction programs which affect the environment, economic, social and natural aspects

43
organizing and scheduling complex strategies or problem solving
system engineering
44
the system approach is composed of:
