In 1997 Finland and Sweden jointly invested in a Heavy Vehicle Simulator,
HVS, from South Africa.
After the first period in Finland the HVS-NORDIC was moved to Sweden and VTI
Road & Transport Research Institute) in Linkoping in September 1998.
A program for research co-operation in the area of accelerated pavement
testing has been agreed
between Finland and Sweden covering the years 1997-2003.
The general objective of the research co-operation is to learn more about
pavement response and
pavement performance. A second but most important objective is to learn about
the HVS-machine itself
and the way it simulate traffic and deteriorate pavements and how this is
related to real pavement
During the first year in Sweden, 1999, tests were performed as planned in the
research program on
typical Swedish low volume road structures. The results from these tests are
presented in this report.
The HVS-NORDIC is a mobile linear full-scale accelerated pavement-testing
machine (HVS Mark
IV). At VTI there is an indoors full-scale pavement test facility where
pavements can be constructed by
ordinary road construction machines.
During the first year in Sweden four structures were tested. The first two
tests (SE01 and SE02) were
performed on newly built pavements (gravel/bitumen type with thin asphalt
surface layers) while the
other two were performed after rehabilitation of the first two after
completed tests. The rehabilitation
measure was milling and levelling (overlay in the milled area) of the surface
layer to get a new even
surface without rutting.
The results evaluated in this report are the results from the pavement
(rutting and deformation). A large amount of data has been collected during
the pavement response
measurements. These data, stresses, strains and deflections during a variety
of test conditions will be
used later for comparison of the test structures and for analysis of
relations between pavement response
and pavement performance.
