A leading civil engineering firm and road contractor, Socogetra, has upgraded three of its asphalt plants, boosting efficiency. The key to the upgrade has been the revamp of the control system, which allows the firm to produce mix specifications more accurately and effectively than before. This is crucial given the increasing requirement for higher quality asphalt mixes for road construction purposes. Socogetra said that it had been using its proven Ammann AS2000plus Control System for many years. Howeve

Bunting Magnetics celebrated 60 years in business by supplying a one of the largest quarries in the US state of Georgia with a Bunting PCB1206-EL Permanent Crossbelt Separator.

New developments in asphalt plant technology are offering better cost efficiency and materials quality for the industry

The Canadian province of Ontario has earmarked around US$1 billion for road repairs and upgrades during 2019. The money is for 123 projects of which around $384 million will go to 20 projects in central Ontario. Northeastern Ontario will receive $218 million for 32 highway projects, mostly along Highway 11 – at nearly 1,800km the second longest in Ontario, Canada’s mostly populous province. Highway 11 runs from the provincial capital Toronto northwards and then westwards to the border with Manitoba pr

The use of ALLU Transformer D-Series attachments are helping boost operations for a Swedish firm. The company, Kits Contractor, is using the units for precision screening and material processing applications for a variety of projects, transforming material arising from recycling, blasting and excavating. The firm bought its first ALLU Transformer in 2014 but found that the Transformer was too small for its needs, replacing the unit with an ALLU DN 3-12 model in 2015, which it still owns and operates.

Advances in road design and construction will deliver cost savings In the past 50 years there have been huge advancements in the automobile industry but the roads we drive on remain nearly unchanged. As cars get smarter so too should the infrastructure that supports them. Our planet is covered in roads. And by 2050 our global network of highways is projected to increase by 60%. Volvo Construction Equipment takes a look at possible technologies for the roads of the future, looking at some innovations

New developments in crushing and screening equipment as well as washing technology will deliver benefits for materials production - Mike Woof writes Competition is tough in the market for quarry material processing equipment, with key firms introducing new systems that are said to boost capacity and performance. Firms offering crushing and screening equipment have expanded their respective ranges, offering additional capabilities for these segments. Mobility and versatility have been key factors in the d

A variety of complex factors are involved in the production of hot asphalt mixes, with the process vulnerable to sudden stoppages of the equipment. The problems caused by a need for unplanned maintenance are high, as the cost of a plant stoppage is high. In order to minimise disruptions to production, new technologies can be used for wear components. Electronic monitoring of asphalt plant motors during production can boost efficiency, replacing corrective maintenance with preventive and predictive maintenan

Marini is offering new versions of its Xpress plant. The first version was the Xpress 2500, but the range is now being widened with the addition of the Xpress 1500, 1500P, 2000 and 2000P models. Andrea Zanoletti is in charge of this range and explained that the plants are designed for maximum mobility. He said, “With only two trailers, you have a complete asphalt plant.” The existing Xpress 2500 model offers an output of up to 250tonnes/hour. However, the new Xpress 1500 and 1500P offer outputs of 150
