Abstract:

The use of impregnation as a means of improving the wear resistance of natural aggregates was investigated. A series of tests were conducted using four aggregates of varying quality, selected from a sampling of 40 different aggregates. Tests performed to evaluate the effect of impregnation on the physical, mechanical) wear resistance and polish resistance properties of the aggregates included: petrographic analysis, Los Angeles abrasion loss, sodium sulfate soundness loss, the British polish wheel, aggregate surface microtexture analysis, and two circular test track studies. The strength of concrete cast with unimpregnated and impregnated aggregate was also tested, as was the affinity of asphalt to bind to impregnated aggregate. Impregnants studied included: MMA-based and styrene-based monomer systems, water based phenol formaldehyde resin, and sodium silicate.
