Performance
The
performance of Trinidad Lake Asphalt has been consistent in
all cases in which it has been applied and has also proven to
provide significant savings in terms of pavement life cycles.
It has been proven to reduce road user costs by 4.0% per kilometer
and to provide overall benefits to society amounting to $1.9m/KM
for weak subgrades and $1.2m/KM for strong subgrades.
A
recent study was conducted to evaluate the economic viability
of airfield pavements incorporating TLA over a broad range of
hypothetical airfield design scenarios. Federal Aviation Administration
(FAA) design criteria were used to develop new pavement and
rehabilitation designs. The designs varied depending on subgrade
strength, traffic type and level, and type of material. The
designs were then compared on a life - cycle cost basis using
guidelines by the FAA. The results of the study indicated asphalt
concrete airfield pavements incorporating TLA (TLAC) can be
cost competitive with or economically superior to conventional
asphalt concrete (AC) or Portland Cement Concrete (PCC) pavement
design scenarios.
