Recycling

Stabiliser/recycling machines are now well proven in road construction applications, giving a stable base layer on which to lay asphalt layers. A wide variety of technologies have been developed to help optimise this process and one proven road stabilisation product called Pavmax that has been used successfully in various markets including Latin America is now being made available worldwide. Introduced by NTI Holdings, Pavmax is a proprietary concentrated liquid, with a multi-enzymatic formulation that

Contractor Nyoni Projects is taking a new approach to two major road upgrades in the North West Province of South Africa. The company is refining its fleet and processes with the use of two new Caterpillarr RM300 reclaimer/recyclers. By introducing these new machines and the associated working methods, the firm believes it can help meet the country’s growing road repair, reclamation and building needs. The firm has seen an increase in productivity since it started using the machines. Maclaud Nyoni, m

Working in a rainforest area can be challenging, but in a rural area outside of Kuching in East Malaysia, a road construction crew was able to carry out a project successfully One of the biggest challenges came from the moisture levels as the area has an average annual rainfall of 4200mm. The saturated soil complicates the construction process on many levels, including stabilisation and compaction. However this heavy moisture content in the soil is a constant for Geocrete Specialist crews, which handl

Super-fine milling is a technique that has been used in Brazil to rehabilitate roads for the World Cup The rehabilitation work had to be carried out speedily and economically, while minimising traffic disruption. To meet these requirements, contractor Fremix Engenharia e Comércio has been using a Wirtgen W200 cold milling machine that is fitted with a super-fine milling drum.

Representing an investment of around US$113 million, Botswana’s A1 national road between Tonota and Francistown is undergoing a major upgrade This single-lane section is being progressively transformed into a north- and southbound dual carriageway, crossing four existing river bridges along the way. A strategically important transportation route for both Botswana and the southern African region, the A1 passes through Francistown, the nation’s second largest city, heading northwards to end at the Zimbabwe b

The market for milling machines is highly competitive and there is an array of firms offering equipment to the global market. German company Wirtgen is the worldwide market leader and has an enormous range of models available, but other companies too are keen to grow market share, with Caterpillar and Roadtec strong in North America and BOMAG, Dynapac and Caterpillar are also pushing hard to build share in Europe for instance. Other companies too are keen to grow their shares of global sales and several of

Chinese firms are growing their expertise in terms of products and international sales – Mike Woof reports China’s major off-highway construction equipment manufacturers have grown in a relatively short period and now number amongst the largest players in the sector. Some of the key firms are looking to boost exports and are providing tough competition, particularly in the emergent markets. Best known for its wheeled loaders, LiuGong has been developing its excavator range, with production of the E

XCMG has seen strong exports, with one deal in particular providing a major boost to turnover - Mike Woof writes It is rare that a single machine order can provide a substantial portion of a large manufacturer’s annual results. However the firm’s massive contract signed with the Venezuelan Government was a major boost to XCMG; the supply of no less than 6025 machines in a deal worth some US$750 million. This order came at an important time for the company when the world demand for construction equipment sl

Çesan has developed the King Batch 280 T/H for applications where customers face problems with a lack of infrastructure. The compact design allows it to be transported anywhere in the world, claimed the company, in just eight containers, significantly reducing transport costs. The company has also developed a mechanical base for the plant, allowing it to be assembled and commissioned on any surface. Previously, asphalt plants required purpose-built concrete slabs for effective installation.

The use of recycling and stabilisation equipment has played a key role in adding new lanes to a congested Italian highway. Running from Bologna to Taranto, the A14 Autostrade has seen a major increase in traffic volumes for several years. Data shows that traffic has increased around 4% year on year with some 110,000 vehicles using the highway/day. The traffic growth trend looks set to continue and this resulted in the Italian Government opting to upgrade and widen the route.
