Abstract:

The feasibility of including open-graded drainage layers in their highway pavements was studied. Before constructing actual pavements with open-graded drainage layers, frost penetration depths and moisture content profiles beneath several pavements in New Jersey were measured. Air and surface freezing indexes were measured at three locations during the 1975-1976 and 1976-1977 winters. Measured maximum frost penetration depths were compared with computed maximum depths for each of 30 test sites. The modified Berggren equation was used to compute the maximum frost depth at each site. Maximum frost penetration depths were computed for hypothetical pavements with open-graded drainage at four of the test sites. It was concluded that open-graded drainage layers would not significantly change the frost penetration beneath highway pavements in New Jersey. It was recommended that test pavements be installed to verify the computations.
