The cost will be billions of dollars. Recent progress in asphalt chemistry makes it possible to build pavements that ride smoother and last years longer.
|
From page 115... ...
This advance will allow highway engineers to specify the asphalt required for Even climates and road conditions. States are already conducting tests to help them select the specific asphalt cements and aggregates they need.
|
From page 116... ...
Together with new insights from Europe and elsewhere about the construction of asphalt mixes, state and local highway agencies are experimenting with technologies to build more durable pavements. Change will take time.

The best approach may be a partnership in which the government provides some components while private companies provide others. The recently passed surface transportation law will greatly expand federal research and development of "Intelligent Vehicle and Highway Systems," or {VHS, and many states are supporting similar efforts.

From page 123... ...
John Roebling, designer of the Brooklyn Bridge, and other notable engineers of the past and present have designed bridges that achieve structural excellence and outstanding appearance at a cost no greater than competing solutions. Their success proves that beauty need cost no more than mediocrity.
