Modern asphalt plants are a far cry from the early models, and are capable of producing a wide variety of mixes at the touch of a button. Patrick Smith reports Cutting-edge software-based control technology makes today's asphalt mixing plants simple and efficient to operate. The tightening of clean air regulations is reducing the emissions from the plants, and the current focus is on the goal of raising the processed portion of reclaimed asphalt (RA) towards 100%, says Ammann Group, which has been involved

Terex has acquired Hydra Platforms, a specialist manufacturer of access equipment designed for bridge maintenance and repair. This business is being brought into the group alongside its Bid-Well brand.

At Steinexpo 2008, Kleemann exhibited its MC 120 Z jaw crusher from the new generation of MOBICAT jaw crushers, as well as the mobile MOBISCREEN MS 16 D screening plant. The MC 120 Z, a classical quarrying machine, is also well suited for concrete recycling, says the German company, a member of the Wirtgen Group. With its 1,200mm wide and 800mm deep crusher inlet, it is designed for a feed capacity of up to 400tonnes/hr, and has a number of features that are said to contribute to its highly efficient operat

The cement factory with the highest output in Europe can be found some 130km east of Istanbul, Turkey, and belongs to NUH Cement. In 2007 the company's quarry in Hereke produced 4.3 million tonnes of limestone, and after on-site processing with additives such as gypsum, iron oxide and coal, this resulted in a yield of 5 million tonnes of Portland cement. Founded in 1966, the company's mission statement is to "serve Turkey's development programme with its production of cement, and huge investments in facilit

Hydrodemolition specialist Aquajet is offering an improved, low-noise power pack for its equipment. Redesigned to meet tough restrictions on noise emissions for equipment used in urban locations, the power pack is also more economical on fuel, an important point given fast rising fuel costs. The firm's hydrodemolition unit is aimed at concrete scarification and removal, and the noise levels from the new Ecosilence Power Pack are so low that normal conversation can continue alongside as it operates. Accordin

Telsmith is expanding its mobile crusher range with the addition of the QuarryTrax Model TI6060, a track-mounted, primary impact crushing plant designed for high-capacity production of up to 800tonnes/hour. It features the firm's heavy-duty PA6060 primary impact crusher, which is said to maximise uptime and minimise maintenance requirements. A key feature of the crusher is its massive, solid type rotor which is mounted on oversized 220mm, wide series bearings. The heavy rotor is said to deliver high inertia

A Dynapac PL350T cold planer helped carry out critical demarcation work on the roads used for the famous Isle of Man's TT motorcycle races. It was used to remove the road markings on the isle in the Irish Sea in readiness for the races. The Dynapac machine is equipped with a special micro milling drum which contains 117 bits, compared to the standard 38, spaced at intervals of 3mm as opposed to the conventional 12mm. In addition, to avoid a sharp edge at the sides of the demarcation area, the drum is slight
