The operation is now using one of the EC220DL excavator models, which has helped boost productivity by some 30%. In addition, the machine is said to be delivering savings in running costs at the Alam Jaya volcanic rock quarry, through reducing fuel consumption by two litres/hour. The site is located close to West Java’s capital city, Bandung, at the foot of the volcano, Tangkuban Perahu. The city is home to 2.5 million people and sits at 768m above sea level, while it benefits from one of Indonesia’s coo

Trimble’s GCS900 3D system for grade control is now available as an upgrade from the 2D laser-guided and sonic/slope systems already offered by Bobcat. The Trimble GCS900 is extremely flexible and can be used on excavators, dozers, motor graders, compactors, scrapers, trimmers, and milling machines. The GSC900 cab be used both as a single unit, or as an upgrade from a GCS600 Grade Control System.

This month we look at two additives from natural sources: a rejuvenator derived from pine trees and naturally occurring asphalt - Kristina Smith writes One of the problems experienced with pavements containing RAP is that, although they exhibit good rutting resistance, they often fail early due to fatigue cracking. Biorefiner Arizona Chemical has just unveiled independent test results for its SYLVAROAD RP1000 Performance Additive that it says demonstrate that the rejuvenator can help create mixes that ar

Advances in asphalt plant design offer major gains in product throughput and quality, while also allowing for warm asphalt and increased recycling The asphalt sector is constantly looking for ways to optimise production, lower costs and improve product quality and consistency. Competition is fierce in the asphalt plant market, with several of the key companies working hard to develop new and more efficient technologies, as well as equipment that is more versatile and more mobile. Advances have been made
