A European road comes to the US

Article Abstract:

The Federal Highway Administration (FHWA) sees great potential for wide US use of stone mastic asphalt (SMA), a heavy-duty asphalt-cement paving reinforced with fibers and a hard stone aggregate. SMA roads, developed in 1967 in West Germany and now widely used also in the Netherlands and Scandinavia, have proved highly durable. So far, SMA test sections placed in 1991 in Michigan, Georgia, Missouri, Wisconsin and Indiana have done well. The FHWA, however, says contractors must be able to maintain quality while keeping down costs and sticking to US production speed standards.

What price congestion management?

Article Abstract:

Plans are on to employ congestion pricing in regulating vehicular traffic by collecting tolls from vehicle users travelling in toll lanes during peak hours. The successful implementation of congestion pricing will hinge on satisfying the tax paying public about the relative merits of this system in regulating rush hour traffic, thereby providing for an environmentally-friendly transport strategy.
