The study deals with the possibility of reducing peak power consumption when melting snow/ice on pavements, by including meteorological prediction models. It is shown that if meteorological predictions are reasonably accurate e.g. more than 5 h into the future, the use of expensive fossil/electrical back-up fuel can be reduced in district heating systems based on bio fuel.

While Portland cement concrete (PCC) overlay has been increasingly used as a rehabilitation technique for deteriorated PCC pavements in the last decade, reflective cracking places a major limit on its durability performance. The use of ultra ductile concrete named Engineered Cementitious Composite (ECC) should arrest such failure mode and greatly enhance the long term performance of the overlai...

External pressures applied to a saturated pavement pore structure are often dynamic due to the repeated tire loading. Therefore, a dynamic permeability constant is more realistic representation of the response of a pavement pore structure than the Darcy’s permeability. To investigate the unsteady (dynamic) fluid flow in asphalt pavements, a 3D fluid flow model was developed using the lattice Bo...

The purpose of this paper is to present the results of various studies which have been made concerning lateral placement of vehicles on rural roads. The term “lateral placement,” as it is used throughout this report, is construed to mean the position of the vehicle on the road in relation to either the right edge of the pavement or to the centerline of the road. Only two-lane roads will be cons...

Of the many improvements in the design of highway pavements during the past two decades, it is doubtful that any have been more important to the life and service of the pavement than the incorporation of the granular base course as a design feature. The true significance of the base course can be more thoroughly understood if one considers the merits of this practice. First, the properly design...
