Studying the mechanical properties of improved cold emulsified asphalt mixtures containing cement and lime

Abstract

Abstract Cold emulsified asphalt mixtures (CEAM) is a cost-effective and ecological technique for bituminous road pavements construction. This investigation evaluates the mechanical properties and durability of CEAM modified using cement and lime as filler replacement. The initial and long-term stiffness modulus, water damage resistance, permanent deformation and fatigue cracking resistance were investigated. To achieve this objective, different laboratory tests were carried out, including stiffness modulus, water damage resistance, wheel tracking and fatigue tests. The results show that incorporating cement and lime in cold emulsified mixtures have an optimistic impact on the mechanical properties and performance. In addition, accelerate the curing time was achieved using such modifiers that are capable of absorbing water.
