Engineering properties of bituminous mixes

As part of the AAPA R&D program a limited pilot study was initiated to assess the viability of a nationwide study and to obtain information on the fundamental properties of typical asphalts produced according to current practice. Ten asphalt plants participated by producing Marshall samples from four typical asphalt mixes according to their current practices. The AAPA pilot study provided a broad picture of the creep and modulus results currently being achieved, and indicated the viability and the potential benefits of a nationwide study. As a result of the study, a specification for rut resistance (creep) was developed. The high recovered viscosities highlighted potential problems in the mixing or sample preparation procedure. The resolution of these potential problems, coupled with strict adherence to the creep specification, may lead to significant increase of pavement service life and riding quality.
