Paving on Algeria's mega highway

A fleet of 53 Dynapac machines is being used by a Chinese consortium to build the central and western sections of the 1,216km Algerian East-West Expressway. The consortium comprises CITIC and CRCC and was awarded the contract for the 169km central and 359km western sections of highway.

A fleet of 53 206 Dynapac machines is being used by a Chinese consortium to build the central and western sections of the 1,216km Algerian East-West Expressway.

The consortium comprises CITIC and CRCC and was awarded the contract for the 169km central and 359km western sections of highway.

To help meet the tight schedule, tough conditions and remote locations, CITIC-CRCC opted to buy equipment from Dynapac. The new Dynapac fleet comprises 20 F141C pavers; a F182CS paver; 18 CC624HFs and 14 CC622HF tandem rollers. The machines are being used to pave and compact the base course, binder course and wearing course.

French asphalt mixtures and testing procedures have been specified, and the testing laboratories were equipped with large wheel trackers, automatic large roller compactors, trapezoidal bending machines and Duriez testing machines. Among those supplying equipment is UK company 5941 Cooper Technology.

"The French asphalt mixture design method is an advanced, performance-based asphalt mixture design method. French asphalts such as EME2 are expensive due to a bitumen content which is around 1% higher than in conventional mixes, but prove cost effective in terms of life cycle cost analysis," said Mr Jia Yu, Vice Chief Engineer at the Jiangsu Transportation Research Institute in China.

For high modulus asphalt concrete mixture, there are two categories: EME is used in base course and BBME is used in binder and surface course. The two materials are both used in the Algeria East-West Expressway with a wearing course of BBMA.

    The latest equipment from Wirtgen has been used to recycle a stretch of Italy’s busy A4 Autostrada, one of the country’s most important highways. The Wirtgen machine was the first WR250 recycler/reclaimer to be delivered to Italy and was put to work on the A4 Turin-Trieste highway where it proved highly productive. The A4 Autostrada runs 522km from Turin to Trieste via Milan and Venice across northern Italy from west to east. The A4 is divided into five segments, the Turin-Milan, Milan-Brescia, Brescia-Pad

    New products, including additives, are coming onto the market to help reduce the cost of producing bitumen. Patrick smith reports. According to Eng. Paolo Visconti of Iterchimica, environmental issues and the health and safety of operators of manufacturing plants and workers laying bituminous mixes have raised long debates on the possible harmfulness of fumes which are emitted when heating these mixes at the temperatures (160-180°C) required for their production. "If, on the one hand, the effects on operato

    Hamburg’s Finkenwerder airport is now benefiting from a new runway surface following work carried out by contractor KEMNA BAU. The company recently used machines from Dynapac to resurface 36,000m2 of the runway track in Hamburg-Finkenwerder, a facility used by Airbus. The airport handles around 10-15 take-offs and landings/day when aircraft are either undergoing flight testing or being delivered to customers, as well as for deliveries of components by transport aircraft. The project was tricky as the

    Construction of Istanbul’s new airport facility is benefiting from the use of a large fleet of machines from the Wirtgen Group. When it is complete, this will be the world’s largest airport and will be able to handle 150-200 million passengers/year as well as 6 million tonnes of freight/year. This will make the facility substantially larger than the world’s current largest airport, the Hartsfield-Jackson Atlanta International Airport, which handles around 105 million passengers/year.
