In this study, two different types of semi-flexible paving mixes were produced using two different types of injection materials. There is a discrepancy between the compressive strength of the two injection materials used, as the compressive strength of the first mixture, which consists of (96% cement, 4% silica fume (SF), was approximately twice the compressive strength of the second mixture, which consists of (75% cement, 25% sand). Study of the mechanical properties and durability of the two types of semi-flexible paving produced, in addition to the effect of the difference in the compressive strength of the two injection materials and their effect on the final performance of the paving. The results of Marshall and rutting tests show that the SFP material shows good stability at high temperatures. The effect of the difference in the compressive strength of the two mixtures was demonstrated in Test results: Compared with the 20.8 MPa sand mixture, the 48.1 MPa SF saw a 39.54% increase in Marshall stability. At a curing life of 28 days, the composite material (CM) also showed better rutting performance than conventional asphalt mixtures.
