The new road construction company belonged to the third group of establishments. At that time, this division meant modest payroll opportunities and smaller investments.

In its first years of operation, the main focus of the young company was introducing a new asphalt concrete technology. Following the launch of the Lagedi asphalt concrete plant in 1961, much consideration was paid in the middle of the decade to the usage of surface-active additives that helped improve the adhesion of road cover and the levels at which the mixture could be processed. The Lagedi industrial base was the first in Estonia to implement the technology elaborated by Johannes Hint, which was further developed in the Moscow Research Institute. This technology allowed producing water-repellent fillers.

Vladimir Allikas, the manager of the company at the time, deserves praise for utilising crushed granite from Karelia. In fact, in the first years of operation of the Lagedi asphalt concrete plant, the company was only able to use crushed limestone for producing the mixture. Thanks to the personal contacts and acquaintances of Mr Allikas, the company was henceforth able to receive high-quality crushed granite from Karelia.
