Asphalt milling, paving & compaction

With safety the priority in road paving, Aggregate Industries says it has launched an automated data gathering system to replace hazardous inspections by crew members. AI says that the new system, known as Automated Inspection and Testing, will see all pavers, rollers and survey vehicles fitted with the latest technology including GPS, infra-red sensors and a data recording unit. All will automatically log high-quality data before, during and after the surfacing process.

The 97th Transportation Research Board meeting was held in Washington from 7-11 January this year.

Controls Group, celebrating its 50th year in business, was one of the exhibitors there, showcasing four testing systems: the AsphaltQube, the

Roads in the US keep failing so the Federal Highways Authority is proposing a new approach to mix design, but what does this mean for tests and testing? - Kristina Smith reports How do you test an asphalt mix for rutting? In the US, the answer could be any one of several tests, depending on which State you are in: Asphalt Pavement Analyser, Flow Number, Hamburg Wheel Tracking Test, Superpave Shear Test or Triaxial Stress Sweep Test. But that could all change. The Federal Highways Agency (FHWA), part of

Sumitomo is offering a series of special pavers, in addition to its conventional units. The modified machines are aimed at a range of specific applications and are based on the standard models. The HTP60W is a tack coat paver based on the standard HA60W model. The machine has the firm’s J- Screed with electric heating as standard and allowing hydraulic extension from 2.3-6m, while compaction is by tamper and vibration. The spraybars allow tack coats to be applied to the full paving width.

A highway widening project in the US state of New Hampshire is being assisted by the use of a gravity-fed asphalt paver. The widening work is being carried out as part of an upgrade for a 32km stretch of I-93, which was started eight years ago. The work is being carried out for the New Hampshire Department of Transportation (NHDOT) on a section of the highway between Exits 1 and 5 from the Massachusetts Stateline to Manchester, NH. According to NHDOT, the project involves widening I-93 from two lanes in
