      <title>SIMULATION OF SALT DAMAGE TO ROADS WITH LABORATORY MODEL EXPERIMENTS</title>
      <link>https://trid.trb.org/View/177034</link>
      <description><![CDATA[It is shown by means of model experiments that evaporation from road bases during construction or service is a cause of upward migration of salt and its crystallization, with resultant damage to surfacings and bases.  However, heaving and loss of density also took place beneath an impermeable seal when specimens contining two per cent MgSO4.7H2O were heated in an oven at 50 deg C.  Water vapour pressure was partly responsible for much of the lifting of the seals encountered.  Downward migration of salt was significant in all cases and should be considered when sulphate--or acid-contaminated pavement layers are used over sulphate--or acid-susceptible supporting layers.
