# experiments were conducted in the lab to determine the moisture resistance of an asphalt mixture. the tensile strength test result

experiments were conducted in the lab to determine the moisture resistance of an asphalt mixture. the tensile strength test results for conditioned and unconditioned asphalt mixture samples are given below. what is the tensile strength ratio (tsr) in percentage for this asphalt mixture (round to the nearest whole number)? tensile strength of conditioned samples: sample 1

1. The tensile strength ratio (TSR) in percentage for this asphalt mixture is 1.3533.
Given that,
Tensile strength of the three conditioned samples is 176 psi, 180 psi, and 184 psi, respectively.
Tensile strength of the three unconditioned samples is 136 psi, 133 psi, and 130 psi, respectively.
To find :  Tensile strength ratio (TSR) in percentage for asphalt mixture
Tensile Strength Ratio =
Tensile Strength Ratio of Conditioned Samples/Tensile Strength Ratio of UnConditioned Samples
Average Tensile Strength
Conditioned Samples- (180+184+176) /3
=180 psi
Unconditioned Samples – (130+ 133 + 136)/3
=133 psi
Tensile Strength Ratio=180/133
=1.3533
Hence, The tensile strength ratio (TSR) in percentage for this asphalt mixture is 1.3533
