By the second half of the 1940s, he had already formulated a method for analysing pile groups with the help of matrices, which he later generalised. In his period as professor of bridge-building and structural mechanics it is his scientific work on the matrix formulation of structural mechanics, with a view to its programming on the computer, that is especially noteworthy. From 1949 until his retirement in 1967, Asplund worked as professor of bridge-building at Chalmers University of Technology in Gothenburg in 1950 he was appointed to the vacant chair of theory of structures following the death of Sven Hultin. He generalised this elegant approach later for other loadbearing structures, making use of matrix formulation. In 1943 Asplund completed his dissertation On the Deflection Theory of Suspension Bridges in which he applied the Green function Π(ε) to this non-linear problem. After returning to Sweden, he set up a contracting company in Örebro specialising in temporary and permanent suspension bridges with small and medium spans for hydroelectric power stations. he also spent time with Robinson & Steinman in New York designing and calculating suspension bridges.

It was there that he was able to play an active part in the upswing in the market for large bridges in the USA at the Melan Arch Bridge Construction Co. Following his examinations as a structural engineer at Stockholm's Royal Institute of Technology, Asplund worked in the USA from 1925 to 1931.
