Construction materials group Boral and truck manufacturer Iveco have launched an aggregate surfacing truck in Australia. The Boral FMAS - Forward Moving Aggregate Spreader – will make the method of spray seal road construction in Australia much easier, according to the two companies. Until now, the process involved road crews working with reversing trucks that applied the aggregate through an elevated tipper body, increasing the safety risks to workers. To improve safety and maximise visibility, th

A Chinese contractor has opted to use RAP in delivering quality roadways at lower cost. The firm utilised an ABA UniBatch asphalt plant from Ammann to achieve this. The Chinese authorities are at present keen to increase the use of RAP in road building, in a bid to reduce the environmental impact of construction projects. However for this to be carried out, the high RAP-content mix must meet high quality standards. Shandong Binzhou Road Construction Corp (SBRCC) has carried out a number of high-profil

The A7 is being widened between Hamburg and Bordesholm from four lanes to six - in some places to eight - to ensure the motorway remains an efficient traffic artery. The aim is to create a pavement with a high degree of driving comfort but which withstands the loads of heavy-goods traffic. For widening the 60km stretch in the Schleswig-Holstein region, consortium Via Solutions Nord and joint venture ARGE A7 Hamburg-Bordesholm opted for steel reinforced concrete paving with an exposed aggregate concrete s

Trimble is expanding its range of machine control technology options for users of graders and excavators with key new releases. One is for the LOADRITE Payload Management system, which can now be utilised on excavators already equipped with the Trimble Earthworks Grade Control Platform. The other systems are new versions of the Trimble Earthworks Grade Control Platform that can be used with graders or deliver automatic guidance for tiltrotators. These are key developments for the firm, boosting its ran
