The Research of the Bending Crack Resistance Ability of Reinforced Concrete Beam Mixed with Emulsified Asphalt
By four-point bending tests on the reinforced concrete beams with emulsified asphalt of different parameters, cracks, deformation and bearing capacity were observed and recorded during destructive process, and then a comparison were made between the experiment results and those of ordinary reinforced concrete beams. The results prove that lower emulsified asphalt dosage (1% to 3%) can significantly improve the overall deformation of reinforced concrete beams; while higher asphalt emulsion parameters (5% to 7%) reduce the beam intensity and do not improve the toughness and overall deformation capacity.
