WHAT IS BEING DONE ABOUT THE AGGREGATE SHORTAGE

Various ways of salvaging aggregate or using substitutes are reported. The use of discarded battery cases for aggregate in making asphaltic concrete, and the use of glasphalt (asphaltic concrete with scrap glass) is mentioned. Aggregate stretching methods imclude those usinglime, cement cement or calcium chloride stabilization of base materials. Crushed waste sidewalks and other paving materials have been recycled. Practical ways to move aggregate from where it is abundant to where it is needed are discussed. This includes the greater use of precast and prestressed concrete forms. Comments are made on the use of manufactured sand. The economics of producing aggregates are discussed.
