A major activity in the
project is full-scale tests of a section of the Guadalajara test
site on Madrid-Zaragoza high speed line. The 21 m long track box is
constructed and filled up with the same material used to build up
section S2 in the Guadalajara site.
Figures 1 and 2 show the filling and compaction operations at the
subballast and ballast levels.
In the course of filling
the box, the necessary tests are performed to control the placement
conditions (density and water content) and sensors are placed at
different levels below the track. Figure 3 presents a layout of the
track box at two instrumented sections. Figure 4 shows the testing
zones and the results of compaction control by means of the SASW
test.
Static
and dynamic tests are performed using the load application system
(servo-hydraulic jacks). Figures 5, 6 and 7 show different views of the track box.
