SUBSTITUTION OF CEMENT BY MICRO-MILLED RECYCLED CONCRETE IN COLD RECYCLED ASPHALT MIXES

Evaluation of the Mechanical Properties of the cement treated Cold-in-Place Recycled Asphalt Mixtures

Cold-in-place recycling (CIR) is an environmentally sustainable alternative for preservation of asphalt pavements. A major disadvantage of this practice is the lower strength of the cold-in-place mixtures. Addition of cement into this type of mixture is a method for increasing its bearing capacity. The effect of cement content on the mechanical properties of the cold-in-place recycled asphalt m...

Use of Recycled and Waste Fibers in Asphalt Concrete

A significant problem associated with asphalt concrete mixtures is the lack of durability resulting from an inadequate asphalt cement content. Additional asphalt cement added to increase durability results in flushing, bleeding and a significant loss In stability. Fibers have been used in stone matrix asphalt and open-graded friction course pavements successfully throughout Europe to allow high...

Creep of Concrete with Substitution of Normal Aggregate by Recycled Concrete Aggregate

Synopsis: This study presents the experimental results on properties of concrete with replacement of natural aggregate by recycled concrete aggregate (RCA). Experimental data on the creep behavior of concrete mixtures (basic and drying creep) was obtained. The replacement factor of natural aggregate by RCA were 0%, 15%, 30%, 60% and 100%, and the test conditions were 50% RH and 20°C. The result...
