ABSTRACT
Countries in the developed world are faced with high maintenance cost of aging transportation highway s
and replacing them in the face of budget deficits and cuts are no longer automatic options. Further, funds
for transport highways have to compete with compelling priorities. In developing and growing economies,
the demand made on highways with the growth in motor vehicles and accompanying economic growth
have ensured the insatiable demand for better, safer, less congested highways and increase in personal
travel. Growth in commerce also imposes growing demands on the highway network. This andmany other
public sector programs such as, educational institutions, housing and defense have largely drawn from
budgetary surpluses in the past.
