Abstract:

Choosing the right material is half the battle in building roads for Alaska. The extreme conditions typical to cold regions require a ; durable, abrasion resistant and freeze-thaw resistant aggregate. Recently the state has been wondering exactly how effective and ; accurate its selection methods are. Currently there is limited information regarding the Alaska Testing Method 313 (sometimes known ; as the Washington degradation test) used by ADOT&PF to test abrasion and degradation value. This project will examine a new testing ; method, the Micro-Deval test — a wet test of how aggregates degrade when tumbling in a rotating steel drum with water and steel balls ; — to determine whether it can provide safe and cost-effective aggregate testing with reproducible results that correlate with field ; performance. The Micro-Deval test is easy, safe, and less costly to perform than traditional testing methods. It is suitable for smaller ; equipment, requires smaller sample quantities and uses a simple procedure. This study will provide data and recommendations on the ; suitability of the ; Micro-Deval test as a as a rapid, simple, repeatable and inexpensive technique for assessing the durability of Alaska aggregates.
