| Abstract: |
Cold-mix asphalts have several advantages regarding
economical, ecological and logistical aspects over hot-mix asphalts. But,
cold-mix asphalts have poor performance and are deteriorated in case of
additional external water entrance before mixture curing is completed. This
study has been focused on to solve these problems and present an alternative to
hot mixtures. Cold-mix asphalt specimens with dense graded aggregate were
prepared according to Marshall
method for emulsified asphalt-aggregate cold mixture design. Portland cement
has been substituted for mineral filler in an increased percent, from 0% to 6%.
Cold-mix asphalt specimens have been prepared with 4.2%, 5.2% and 6.2% of
residual asphalt contents. Indirect tensile test, static and repeated load
asphalt creep tests, and water damage test have been performed on the
specimens. In addition to these tests, the moisture losses of specimens that
took place in time are also measured. Based on the experimental work, it has
been concluded that dense graded cement modified emulsion mixtures are of great
performance compared to hot mixtures with the same aggregate grading and
bitumen content. A mathematical model has also been developed for determining
the resilient modulus of cold-mix asphalt.
