Abstract: A system for repairing roads is provided. The system includes a highly strain tolerant, substantially impermeable, reflective crack relief interlayer. The interlayer includes a polymer modified asphalt binder mixed with a dense fine aggregate mixture. About 100% of the aggregate should be able to pass through about a 9.5 mm sieve. The interlayer mix is designed using volumetrics and verified using a Flexural Beam Fatigue test and a Hveem Stability test. Preferably, an HMA overlay that is compatible with the interlayer, as well as the demands of local traffic, is placed over the interlayer so that a protected, smooth road surface is provided. The system may delay the first appearance of cracks and the severity of cracks for several years compared with traditional hot mix overlays and extend pavement service life.

Abstract: A method of selecting an asphalt binder for use in constructing a high modulus layer of bituminous pavement is provided. This method includes measuring the complex shear modulus of one or more binders at a temperature of not more than about 30° C., measuring the creep stiffness of one or more binders at a temperature near the lowest in-service temperature at the depth of the layer at which the bituminous pavement is being placed, and selecting an asphalt binder for the high modulus layer using the complex shear modulus and creep stiffness measurements. A further aspect of the present invention is a method of formulating an asphalt binder that has a desirable complex shear modulus and creep stiffness for use in making the high modulus layer. This method of formulation includes mixing a stiff asphalt binder and a soft asphalt binder together to form a binder having a complex shear modulus of at least about 2 MPa at 30° C.
