Title: TEST RESULTS AND ANALYSIS OF THE ALF TRIAL AT BENALLA, VICTORIA.
Abstract: The second trial was carried out with the Accelerated Loading Facility on a section of crushed rock pavement surfaced with spray seal and subjected to heavy traffic loading. The pavement was subjected to a total of 1 400 000 cycles of a nominal load of 80 kN and pavement response and performance was monitored in terms of residual and resilient deformation, the latter both on the surface and within the pavement. Although the pavement did not deteriorate structurally, the surface seal had to be fully rehabilitated twice and many minor repairs were carried out in order to maintain a waterproof surface. Analysis of the results indicated the stress (load) sensitive nature of the pavement. Ignoring the non-linear characteristics of the pavement led to significant errors in the estimation of pavement life under different load magnitudes and traffic conditions. Exponents for the load-damage function were found to be a function of the criterion itself; they also indicated load-dependent pavement response. The in situ CBRs of the material after the conclusion of trafficking were much higher than those indicated by preliminary testing.
