Established by former quarry planner Edward Hamilton and his wife, Genia, Hamilton Aggregates in the US state of Arkansas has grown from a single 0.202 hectare quarry to a three quarry operation in just seven years. The firm’s Bonds quarry in Clinton had an initial plant consisting of an Extec (now Sandvik) C12+ mobile jaw crusher and an E7 mobile scalper, which were rented from Brian Costello from Crushing Tigers; the local distributor of Sandvik mobile crushers and screeners. Showing sound business sense,

In 2012 Benninghoven were commissioned by Kostmann, an Austria-based consortium of companies involved in the production and refinement of raw materials, to build an asphalt mixing plant that included a stone tower silo system. The plant - TBA-3000-U –was to be sited at Weitendorf, a location offering good access to the motorway, the Styria regional capital, Graz, and the Austria-Slovenia border. However, the close proximity of agricultural land and private residential areas called for an adherence to strict

Ammann and Gujarat Apollo Industries Ltd (GAIL) have signed binding agreements which will see Ammann Group pay just under US$59 million to acquire a 70% share in the Indian company’s plant and machine business. GAIL’s core products include road pavers, asphalt mixing plants, bitumen sprayers and compaction machines. The joint venture is seen by the Ammann Group as underscoring its global growth strategy while heralding its entry into the Indian road building equipment market, tipped for strong growth thank

A leading asphalt plant manufacturer is playing a key role in the upgrade of a major European airport, while another is said to have created one of the most modern plants in Europe. Meanwhile, a host of new plants and plant concepts have been, or are about to be, unveiled. Guy Woodford reports Intrame says its ultra-mobile UM-280 asphalt plant has played a key role in the resurfacing of the runway and taxiways at Gatwick Airport in southern England – the busiest single runway airport in the world. Around 35

At a diminished Asphaltica exhibition, many of Italy’s asphalt sector companies spoke of the importance of overseas markets. Kristina Smith spoke to some of the firms seeking export success. Italy’s 6th Asphaltica show, held in Padua in November last year, provided a snapshot of the challenging economic conditions faced by the country. 2012 was the year when Italy felt the impact of the economic crisis which many other European countries had already suffered. Reflecting this, the exhibition was half the siz

Global demand for construction aggregates is set to increase 5.2% a year until 2015 to 48.3 billion tonnes, according to research by The Freedonia Group in the United States. The same source tips China alone to account for half of all new aggregate demand worldwide in the period 2010-2015. Guy Woodford reports on the growing importance of the Asian aggregates market. China is already the biggest nation for aggregate production and use in the world, and the competition among the giants of aggregate productio

Why durability is crucial for both emerging and developed economies, and how warm mix technology can help disaster recovery - Kristina Smith reports. When CORE Construction, a 100% owned Ghanaian company, started working on road construction projects five years ago, it was difficult to source the right bituminous mixes. “In the past, most construction firms had a number of challenges when it came to bituminous works, since the local capacity was not well-developed,” said CORE CEO Frank Lartey. CORE’s soluti

Three Sandvik DX800 top-hammer hydraulic drills are said to be playing a key role in developing the new US$92 million Norfolk Southern Intermodal Site within Charlotte Douglas International Airport in the US state of Georgia. The site, in the Georgia town of Austell, encompasses nearly 200 acres of ground, with a granite rock formation lying less than 100m away from a very active runway of the very busy airport. The ground will be turned into an ‘intermodal yard’, meaning that cargo carried there on Norfolk

Early evaluation of surfacing work on the M90 at Rosyth – the first major application of Scotland’s new TS2010 specification – has earned positive praise. Transport Scotland’s determination to obtain pavement that is durable, long lasting and safe (especially in early life) is clearly apparent on the M90 just north of the Forth Road Bridge. Here surfacing has been carried out this spring to TS2010, a tough new specification designed to ensure thin surfacing pavements that work. And the initial prognosis is

New developments will broaden the asphalt paving market - Mike Woof reports. A new approach to materials could help address rising bitumen costs. Increased use of recycled asphalt pavement (RAP) in road construction can cut a major chunk from paving costs, with an array of technologies now available. In the US, RAP is one of the most widely recycled materials and current techniques allow roads built with this material to perform well for all traffic conditions. Some European countries are also making widesp
