Bituminous road surfacing in high stress areas

The design of bituminous road surfacing materials in high stress areas such as climbing lanes is of considerable concern to pavement engineers. Past experience with conventional Marshall design mixes has indicated shortcomings even though the mixes are produced to within the required tolerances. This is evident by excessive rutting and shoving soon after construction. The solution recommended in this review is to design and build a structure whereby aggregates carry the load, and bitumen waterproofs and binds the aggregates. The aggregate grading structure should be formulated such that all the traffic loads are transferred through point-to-point contact between the aggregates.
