FUD - SALA : stabilization of unbound layers on a road section

The objective of the project is to develop two applications, in which a subbase is stabilized using binders, for full scale demonstration. The binders that were used are cement, Merit 5000 and fly ash. The work indicates that stabilization of unbound layers are expected to improve the bearing capacity of the road construction though the total depth of the structure is reduced. The developed applications are durable against freezing and thawing cycles, will not be lifting due to frost and are not considerably insulating. In a life cycle cost perspective the applications are likely to be favourable. Next step is to perform a full scale demonstration where amongst other knowledge regarding determination of modulus, frost durability and cost aspects related to maintenance should be developed further.Godkänd; 2008; 20091112 (andbra
