IMPROVEMENT OF WEAR-RESISTANCE PROPERTIES OF NATURAL AGGREGATES BY MATERIALS IMPREGNATION
The highway construction industry uses several billion tons of aggregate annually in the construction of highway pavement and bridge decks. In the interest of highway safety and maintenance, it is important that the aggregates used for pavement surfacing systems possess a high resistance to polishing as well as a high resistance to wear and weathering. Unfortunately, the supply of natural aggregates satisfying these criteria is being rapidly depleted in many areas of the United States, necessitating the shipment of large quantities of high quality aggregate to these regions. The preliminary phase of a research program being conducted to investigate impregnation materials and techniques to improve the wear resistance properties of natural aggregates, thereby making them acceptable for use in pavement surfacing systems. Test results obtained during this phase of the research program are discussed.
