Five paving mixtures typical to utah and nevada were prepared with and without 1.0 And 1.5% (By weight of aggregate) of dolomitic type s or normally hydrated high-calcium (type n) lime. The temperature and moisture susceptibility of each of the mixtures was determined. A slight increase in mixture stiffness resulted from the addition of either type of lime. Moisture sensitivity substantially decreasedfor all mixtures when lime, regardless of type, was used. The magnitude of the improvement appears to be unique for each asphalt-aggregate combination.
