Cold Recycled Bitumen Emulsion Mix Design for Roads in the Tropics

A flexible road pavement structure must principally be designed, such that it will facilitate smooth and safe ride (or passage of vehicular traffic both in size and weight) throughout its design life. These requirements by implication pose the two challenges of ensuring structural and functional viability of the road pavement throughout its design life. The design of course must be within the budget constraints. These are accomplished by proper mix and structural design of the pavement. This book presents the process of cold recycled bituminous emulsion mix design. The cold mix design entailed optimising the volumetric of the materials involved using both the ITS and ITSM tests. Although the design principle adopted here is used for the well-established hot mixtures, it should continue to be used for cold mixes until their nature is fully understood. More importantly, the trend in the industry is that such cold mixtures should meet same requirements set for hot mixtures.
