	%X The paper shows examples for the (environmental)
optimization of production processes for asphalt mixtures applied for
typical road pavements in Austria and Switzerland. The conducted
“from-cradle-to-gate” LCA firstly analyzes the production one cubic
meter of asphalt and secondly all material production processes for
exemplary highway pavements applied in Austria and Switzerland. It
is shown that environmental impacts can be reduced by the application
of reclaimed asphalt pavement (RAP) and by the optimization of
specific production characteristics, e.g. the reduction of the initial
moisture of the mineral aggregate and the reduction of the mixing
temperature by the application of low-viscosity and foam bitumen. The
results of the LCA study demonstrate reduction potentials per cubic
meter asphalt of up to 57 % (Global Warming Potential–GWP) and 77
% (Ozone depletion–ODP). The analysis per square meter of asphalt
pavement determined environmental potentials of up to 40 % (GWP)
and 56 % (ODP).
