(7) two pg70 asphalt concrete core samples are taken from an existing flexible pavement. each sample has a diameter of 4 in. and a thickness of 2.5 in. (a) if the first sample, tested in the indirect tensile apparatus, failed under a maximum load of 2,500 lbs, calculate the tensile strength of the pg70 asphalt concrete mixture. (b) under a dynamic load of 50 lbs, applied on the second specimen in the transducer arrangement for the diametral modulus test, a horizontal recoverable deformation of 0.076*10-3 in. is measured at 70o f. what is the resilient modulus of the asphalt concrete (ac) layer in the field (use the equation on page 283)?
