into a solid, rather hard state at a temperature
slightly less than 1370°k, in crystalline form.
This method requires more time and energy, but
will result in a material much harder and more
durable, and should not be separated into such
small plates, but could be prepared as a continu-
ous surface (of more interest for lunar tracks).
in addition, the lunar soil has the adecuate char-
acteristics for the manufacture of these basaltic
blocks or plates because, unlike terrestrial basalts,
are not affected by the weather or contamination
by external agents. The Table 8 exhibits the major
characteristics of these molten lunar basalts.
The pavement used in roads and highways on
earth has between 15 cm-25 cm thick, and 30 cm
for airport runways. Given that the gravity on the
Moon is one sixth of the earth and therefore the
weights applied on the pavement will be six times
smaller, the required thickness of pavement on
lunar roads would be between 2.6 cm-4, 3 cm,
while for landing runways might be sufficient with
a thickness of 5 cm. To build these tracks, nasa
has made several designs robots pavers, which
would be responsible for smoothing the lunar soil
to place the plates of basalt.
