Abstract:This report documents the construction of a Chemkrete modified asphaltic concrete field trial and presents first year performance data. Normal plant and roadway operations were maintained throughout the production of the Chemkrete modified mix. Initial binder testing, however, indicated the possibility of non-uniform blending of the Chemkrete additive. An additional problem surfaced during production control and acceptance testing: stabilities grater than the control mix, the low initial stabilities may require changes to control and acceptance procedures.
Performance evaluations will be conducted on an annual basis and will include Pavement Condition Ratings, structural evaluation and the examination of binder properties (as extracted and recovered from roadway samples). Similar to initial production testing, the recovered binder from the first year's evaluation seems to indicate non-uniform blending of the Chemkrete additive. There was no other discernable difference in performance.
