A crushing unit from Austrian manufacturer RM is being used to produce materials for road infrastructure projects in Indonesia. The unit has replaced a combination of jaw and cone crushers used previously on the project. The RM 70GO! 2.0 has been used to crush river basalt and is the first mobile RM crusher to have been utilised in Gorontalo, located in central Indonesia.

The new AMOPEPPER plant is now being tested at the AMOMATIC facility in Paimio, Finland. The way the system works is that the plant can be moved to an area where RAP material is available or material can be transported to the plant area. Once these two are ready, RAP material is fed into the process and the end result is hard stones of two different sizes as well as bitumen pellets. These are squeezed so hard that nearly all moisture is eliminated. It has already been tested that these pellets can then

A good quality mix plays an important role in road construction and the asphalt manufacturing process starts with the mix design in the laboratory, which takes place under controlled conditions and depends on the materials available locally. A mix design that matches the plant's limitations has a higher probability of success. The properties of the aggregates, such as water absorption, abrasiveness, and the equivalent sand index, may influence the quality of the mix produced in the plant. In the laboratory

An asphalt plant from ADM has helped in the reconstruction of the runway at South Caicos Airport. Herzog Caribbean recently took delivery of its new asphalt plant to supply material for the runway overhaul on South Caicos Island. The plant, an ADM EX120, delivered 23,000tonnes of material for the project without any downtime, allowing for an April 2017 completion. A division of Missouri-based Herzog Contracting, Herzog Caribbean operates out of Providenciales, the capital city of Turks & Caicos, British We

There are important methods aimed at the reuse and recycling of reclaimed asphalt pavement (RAP) a number of problems have to be solved however, mainly concerning the elimination of moisture content and how best to heat the RAP without damaging the binder. When RAP is used in percentages of up to 30-40% of the final mix, heating can be carried out through direct contact with hot aggregates. On the other hand, in order to use higher RAP percentages, up to 100%, the plant has to be fitted with a specific h

Vert Bleu has used UltraCrete Instant Road Repair to repair dangerous potholes in and around tunnels in the Rhône-Alps region of France. Vert Bleu, working for Instarmac, a manufacturer and distributor of cement- and bitumen-based products, was focussed on a roundabout connecting the French highway to a tunnel. Regular heavy passenger car traffic, along with the braking and turning from heavyweight vehicles and trucks, had caused severe damage to the highway’s wearing course. Numerous other cold asphalts

Pilipinas Shell is investing around US$13 million in a new bitumen production facility in Tabangao, Batangas. With President Rodrigo Duterte’s administration planning to spend P8.2 trillion on infrastructure during his six-year term, Shell wants to be ready to participate fully. "In terms of target market, for the moment, we are actually in a good position because we are about 50% of the bitumen market in the Philippines already. We aim to continue to increase that," said Pilipinas Shell’s president and CEO

Gazprom Neft and the Government of the Omsk Oblast announced a Cooperation Agreement for the supply of bitumen and bitumen-related products in June this year. Gazprom already supplies bitumen to the region, which is in south-western Siberia, but this deal will see the volume and range of materials increase. Gazprom Neft Bitumen Materials will supply not only materials but expertise too, advising on material selection, mix design and the management of road construction projects. “The Omsk Oblast is one of
