Abstract:

Quality aggregate availability in southern Louisiana has reached an alarmingly low level, while naturally occurring materials (sands) have been ignored due to their poor structural properties. Recent research reported by Chem-Crete Corporation indicates that structural properties of sand mixes incorporating Chem-Crete binder compare favorably with dense-graded asphaltic concrete. This binder, processed according to a new refinery technique, is purported to improve asphalt properties such as strength, durability, temperature susceptibility and water resistance. These attributes and other properties of sand/Chem-Crete mixes are examined in this report. Generally, upon curing, sand mixes utilizing Chem-Crete binder demonstrated properties equal to or superior to Louisiana's dense-graded Type 1 asphaltic concrete (1200-pound stability).
