Widening existing bridges is an important way to meet the surge in traffic demand, which often carried out a that does not interrupt traffic. To investigate effect of vibration on compressive strength high-strength concrete and splitting new-to-old interfaces, initial final set time C60 was first investigated this article. Then, disturbance parameters were determined. Later, at different stages under out. Finally, tensile specimens with loading modes tested. The test results indicated vibrated for 3 h cured 3, 7, 28 days increased by 4.3%, 5.7%, 11.9%, respectively; those 7 decreased 13.7%, 20.4%, 19.9%, 5 obvious. When loaded along old new joint, cracked joint; strengths specimen disturbed significantly decreased. perpendicular still decreased; while direction This study can promote widening improvement highways bridges, save resources improve land use.
