CREEP INDUCED BEHAVIOUR OF RESURFACED PAVEMENTS. SOME STUDIES WITH THE AID OF BEAMS SUBJECTED TO A TEMPERATURE WAVE AND LOADED UNDER PLANE STRAIN CONDITIONS

One of the reasons for maintenance of asphalt pavements is hazardous rut formations. If the ruts are attributed to insufficient resistance to permanent deformations the proper maintenance procedure may be unclear. In this paper the effect of five different maintenance activities are evaluated. These have been performed on an unstable part of E-4 at Graenna on the East side of the Lake Vaettern. A loading test in the laboratory under plane strain condition is described. It operates under the influence of a temperature variation which is similar to what is expected in the road during a summerday. Beams taken in the cross section of each test surface have been loaded in the laboratory. A comprehensive part is devoted to the justification of the loading under plane strain conditions. Comparisons are made with the permanent deformation caused by a rotational symmetric moving load. The material is assumed to be homogeneous in dilatation as well as in shear. The analysis reveals that certain time dependent loadings under plane strain conditions produce the same result. One of these ought to be applicable in practice. The results with the used loading conditions in the laboratory are discussed. (Author/TRRL)
