Analysis of Physical and Mechanical Properties of Mud Brick Enhanced with Asphalt Recycling

Abstract

Introduction: In this work we have carried out a physical and mechanical analysis of the improvement of the material of mud brick (in Colombia it is known as "Adobe") with recycled asphalt. Objective: Evaluate in the laboratory, the behavior of the material of mud brick with the addition of recycled asphalt. Method: In order to meet the objective, quantitative research was conducted to characterize the physical evidence by analysis of particle size and density. The same tests characterize the mechanical strength in mud brick blocks, built with zero, two, four and eight percent recycled asphalt doses. It is based on laboratory testing Results: According to the results obtained in the tests, mechanical properties, such as resistance to compression and bending were improve, adding recycled asphalt to Mud brick and in comparison with samples without content of asphalt. Conclusions: The mud bricks stabilized with two percent of recycled asphalt have the best performance in compressive and flexural strength according to laboratory testing.
