TWO Australian resource companies have landed a construction contract for a coal hauling and access road in Indonesia.

Dust management and soil stabilisation company Reynolds Soil Technologies (RST) together with Proof Engineers will design and build the multi-million dollar road at Kalimantan coal mine.

Expected to be a one-year project, Proof Engineers director Sebastian Karsas said the haul road, once complete, will demonstrate how well designed and constructed roads can support Indonesia's growing coal mining industry.

"Though coalmining in Indonesia is an expanding market, distribution still remains a challenge due to difficult terrain and damaged roads," Mr Karsas says

"The haul road has been designed to ensure safety during the transportation process as well as significantly increase production rates, while RST's products will improve the road's structural integrity, reduce road maintenance and protect the road's surface from rapid deterioration and damage.

"We are estimating the haul road will take up to a year to construct, due to weather and environmental challenges that currently exist in Indonesia -however once complete, the haul road will perform well in these conditions:

RST Operations and Technical Director David Handel says they had specifically formulated their products to be used to cater for the Indonesian road after extensive research since entering the Indonesian market.

"RI-B is a powdered speciality blend which acts as an effective road stabiliser and Rl9 is a dust control agent, designed for use in the site standard haul road watering program to greatly improve water penetration agglomerate fine particles and consolidate haul road surfaces," he says.

"In addition Rl3 has been designed to cater for Indonesian clay soil types, and when applied over open soil material- it enables soil fines and gravel to attain a higher density and strength.

"This application allows the treated material to be compacted with less water, while improving material density by reducing the void spaces between the soil particles, simultaneously limiting the water's ability to permeate through the treated material.
