Research on Mechanical Response of Thiopave Modified Bituminous Pavements

Based on the excellent high and low temperature stability of Thiopave bituminous pavements,the finite element software was adopted on the computation of the typical semi-rigid basic bituminous pavement,as a result,different bituminous pavement mechanical responses were obtained,then the contrast research was done and the main conclusion went as follows: the bottom curved tensile stress of the Thiopave asphalt pavement is obviously bigger than the SBS asphalt and common bituminous pavement;the road deflection value is smaller than the SBS asphalt and the matrix bituminous pavement;the Thiopave asphalt pavement layer bottom curved tensile stress increases and the road deflection value decreases gradually along with the increase of the SEAM quantity;the road deflection value and bottom curved tensile stress of pavements reduce gradually along with the increase of the bituminous pavement thickness.
