	%X This paper presents an experimental study on
structural performance of an innovative noise barrier consisting of
poly-block, light polyurethane foam (LPF) and polyurea. This wall
system (flexi-wall) is intended to be employed as a vertical extension
to existing sound barriers in an accelerated construction method. To
aid in the wall design, several mechanical tests were conducted on
LPF specimens and two full-scale walls were then fabricated
employing the same LPF material. The full-scale walls were
subjected to lateral loading in order to establish their lateral
resistance. A cyclic fatigue test was also performed on a full-scale
flexi-wall in order to evaluate the performance of the wall under a
repetitive loading condition. The result of the experiments indicated
the suitability of flexi-wall in accelerated construction and confirmed
that the structural performance of the wall system under lateral
loading is satisfactory for the sound barrier application. The
experimental results were discussed and a preliminary design
procedure for application of flexi-wall in sound barrier applications
was also developed.
