Abstrait:

In order to study the effect of PVA fiber dispersion on the performance of cement-stabilized macadam as pavement base material, the dispersion factorFvcis introduced (Fvc = 1 − Cvc,Cvcrefers to dispersion coefficient of relative mass fraction proportion coefficient) as a factor to judge the dispersion degrees. Besides, the connections amongFvcand the compressive strength of the splitting strength of cement-stabilized macadam in various curing periods are analyzed. The research conclusions reveal that (1) when the mass ratio of PVA fibers to coal ash is higher than 1 : 50, resultingFvc > 0.95, it means the PVA fibers can disperse evenly in the cement-stabilized macadam; (2) both the compressive strength and the cleavage strength of cement-stabilized macadam with PVA fibers are proportional toFvc; moreover, both the compressive strength and the splitting strength of cement-stabilized macadam with PVA fibers are obviously stronger than those in the common macadam; and (3) under the same curing period and with the sameFvcvalue, both the compressive strength and the splitting strength in the first type of cement-stabilized macadam (volume content: 0.9 kg/m³ of PVA fibers) are stronger than those in the second type of cement-stabilized macadam (volume content: 0.6 kg/m³ of PVA fibers).
