Macadamised Roads and Dust

Characteristics of Fugitive Dust Generated from Unpaved Mine Haulage Roads

Fugitive dust is generated along unpaved mine roads from intermitlent equipment traffic. Typically. the majority of such traffic consists of trucks hauling either mine product or waste from the surface mine pit andlor the processing plant. Fugitive dust generated along these unpaved mine roads includes particles of all sizes which become airborne. The potential hazards include the deleterious e...

O1: Roads Safety and Neurotrauma

Road traffic accidents account for approximately 3000 deaths on a daily basis, and 50 million injuries and 1.2 million deaths each year. In low-income and middle income countries, road traffic accidents account for 85% of deaths and 90% of annual disability. Casualties of this magnitude are a serious problem throughout the world and create a significant impact on society. In addition, neurologi...

Electric Arc Furnace Slag and Blast Furnace Dust, Use for the Manufacture of Asphalt Concrete for Roads

This paper analyzes how feasible it is to use electric arc furnace slag as coarse aggregate, and blast furnace dust as fine aggregate in the manufacture of hot asphalt concrete for roads. Three mixtures were designed using the Ramcodes methodology, the M1 mixture of control with conventional materials, the M2 mixture replacing 50% and the M3 mixture replacing 100% of the conventional aggregates...

Evaluation of Dust Suppressants for Gravel Roads: Methods Development and Efficiency Studies

Long-Term Efficiencies of Dust Suppressants to Reduce PM10 Emissions from Unpaved Roads.

A 14-month study was undertaken to assess the long-term efficiencies of four dust suppressants (i.e., biocatalyst stabilizer, polymer emulsion, petroleum emulsion with polymer, and nonhazardous crude-oil-containing materials) to reduce the emission of PM10 from public unpaved roads. PM10 emission rates were calculated for each test section and for an untreated section for comparison purposes. E...
