New machines are now coming to the international market, with Chinese firms producing a particularly strong showing. At the last BICES exhibition in Chinese capital Beijing, one of the most notable developments was how many of the country’s equipment manufacturers now offer ranges of soil compaction and/or asphalt compaction equipment.

Innovations in drilling and blasting and crushing and screening are bringing major economies of scale to aggregate production operations. Drilling and blasting is an area where new technology is offering major saving to quarrying companies. This is another important factor in the quarrying process, as inefficient drilling and blasting can have major financial repercussions.

MB S.p.A. of Italy has launched the first of a new generation in its bucket crusher range following the successful launch of the units in 2007. According to the company, which currently exports to more than 100 countries, applications for MB bucket crushers, which fit a variety of excavator sizes (and which also include an iron separator) are many. They include demolition, general construction, excavation work, earthmoving, quarry and mines, vineyard deep ploughing and environmental remediation. However,

Mexico-based Grupo Pinfra was one of the country's first aggregate producers to invest in mobile crushing and screening equipment. Twenty years on, the company is still confident that mobile equipment is key to meeting demand and has just expanded its fleet. In 1991, Pinfra took delivery of two Metso Minerals Lokotrack LT125 mobile crushers and these have now clocked up 30,000 working hours. Nonetheless, there is still plenty of life in these machines and while the newly acquired LT140 jaw crusher takes

A wide variety of new equipment and technology to assist production at asphalt plants is about to be launched onto the market, while asphalt producers are continuing to look at greener working practices. Guy Woodford reports Lintec, in partnership with Loesche, recently created what they say is the world's first containerised Coal Mill Plant for independent coal dust supply at the jobsite which offers mobility and high economic efficiency through the substitution of gas or oil with coal. The mobile co

A variety of systems are available for quickly and efficiently removing water from roads as Patrick Smith reports The presence of water in a highway layer reduces the bearing capacity of the road, and in doing so it also reduces the structure's lifetime. Indeed, the recent extremely cold winter in many parts of Europe has shown that in colder climates there is a risk of frost damage when water is present resulting in costly potholes, so drainage systems performing properly are important in road design.

A Colombian contractor tackles specifications for asphalt road work with Astec equipment.Award-winning Colombian contractor MHC has upgraded its Astec Portable Double Barrel plant to handle highway and other projects. The plant, installed in Bucaramanga, equipped with two RAP [recycled asphalt pavement] bins, a Double Barrel Green System, and one New Generation silo was bought by MHC in 2009. It has now received a second silo and a truck scale extension.

Marini has been involved for some years in supplying asphalt plants to Indian companies involved in road and airport construction programmes. Through Marini India, the Fayat Group company installed what it claims is India's "greenest asphalt plant" for Navayuga Engineering Company, which chose a Marini MAC plant for work on the PPP Armur-Adloor Yellareddy road project on the Nagpur-Hyderabad section in central India. Marini says that its new generation of energy-efficient asphalt plants has been devel

Bitumen technology is benefiting from years of research and development - Kristina Smith. On a 2.7km loop of road in Auburn in Alabama, US, a lorry driver drives his triple-truck round and round. During his eight-hour shift, he will have covered 544km, with another driver waiting to take over from him for the next shift. Their mission is to seriously damage the road. This is the National Center for Asphalt Technology (NCAT), where sponsors from states and private companies pay to test out new materials and
