Much Asphalt has upgraded all its plants to incorporate state-of-the-art control systems, as well as fitting filter baghouses to keep emissions well below legal limits. As a responsible manufacturing company Much closely monitors its carbon footprint and all branches are measured against world best practice guidelines.
One of the biggest contributors to carbon footprint is the furnace fuel oil used to dry and heat aggregates and Much is continually investing in advanced burner technology to reduce its fuel consumption. The flagship asphalt plant in Benoni has been converted to run on natural gas.
Much Asphalt has developed state-of-the-art technology for the automation, operation and process control of its asphalt plants.
Continuity of supply is assured through high level maintenance management, supported by teams of technically competent people.
Based on wholly South African designs, systems installed are designed to produce the highest quality products in compliance with the ISO 9001:2000 quality management system.
Much Asphalt has upgraded all but two of its 17 static plants in South Africa to include recycled asphalt in new asphalt mixes. These plants can now incorporate between 10% and more than 50% recycled asphalt. The two plants not enabled for recycling are located in remote areas where recycled asphalt is not freely available.
Asphalt pavement is 100% recyclable and reusable
Amman mobile plant is also capable of handling 40% RA.
Asphalt pavement is 100 percent recyclable and reusable, with recycled asphalt (RA) milled out of the surface layers of an existing asphalt paved road and then crushed, screened and combined with virgin asphalt mixes for new surfacing applications. RA is added to hot or warm mix asphalt in different quantities depending on the engineering design of the project and the capability of the manufacturing plant.
Reclaiming asphalt offers financial savings in material costs, energy costs and total job costs. Mixes with RA show similar performance to conventional mixes.
There is a strong case for higher percentages of RA in new asphalt mixes as the aggregates and bitumen used in the production of asphalt are non-renewable and increasingly rare resources. The ongoing shortage of bitumen in South Africa necessitates expensive long distance hauling when local supply is unavailable.
