Laboratory Evaluation of Trinidad Lake Asphalt
The Department has examined several asphalt cement additives over the last 6-8 years in an attempt to produce an increased strength dense graded asphaltic concrete or an acceptable mix using marginal sand aggregates. Trinidad Lake Asphalt, a naturally occurring asphalt, is another material purported to enhance mix properties. Trinidad Lake Asphalt in both an epure and a powder form was examined in the laboratory. Laboratory testing included: binder properties testing of combinations of Trinidad with three asphalt cements at three levels of addition; binder durability testing using the Thin Film Oven; Marshall optimization of mix design for a low stability dense graded mix, a high stability dense graded mix and sand mix each at three Trinidad addition levels; water susceptibility testing; and, fundamental properties testing. Also, an economic analysis was performed. An economic analysis on either a first cost or life cycle basis showed that a Trinidad mix would have to perform an additional two years beyond a conventional mix in order to achieve economic parity.
