For road construction engineers, connections between two islands

separated by saltwater have always been a big challenge. Careful and

sophisticated planning is essential, as is choosing the best material to

ensure that this connection is long lasting and safe.

In Korea, the engineers who designed the Seohae Grand Bridge which

connects the island of Pyongtaek (Gyeonggi-do) with Dangjin

(Chungcheongnam-do) at mainland South Korea, conducted extensive

studies, and finally decided to use SMA with VIATOP® as the best

solution for the surface layer for this important connection.

Today, after 16 years in service they have received confirmation that their

decision was the correct one, as the surface layer of SMA with VIATOP ®

is still there, and still offers an excellent performance.

Spain has two basic climatic areas:

▪ The coasts (both Mediterranean and Atlantic):

average minimum temperatures around 10 ºC, and

average maximum temperatures around 30-35 ºC

▪ The inside with a mild continental climate with cold

winters: average minimum temperatures around -5 ºC,

and average maximum temperatures around 40 ºC (this

is the case of Madrid)
