Abstract:

In order to investigate the effect of some factors on the unconfined compressive strength(UCS)for composite soil stabilizer-stabilized gravel soil(CSSSGS), the orthogonal test is adopted to set up the experimental scheme. Three levels of each factor are considered to obtain the change laws of UCS, in which the binder dosages are 8%, 10%, and 12%; the curing times are 7, 14 and 21 d; the gradation n are 0.3, 0.35 and 0.4; and the degrees of compaction are 95%, 97%, and 99%. The range analysis clearly indicates that the influence degree of the four factors on UCS is in such an order: dosage, age, gradation, and degree of compaction. The variance analysis shows that only the composite soil stabilizer dosage can significantly affect UCS. In road construction, the examination of composite soil stabilizer dosage and base-course maintenance should be given much more attention to obtain satisfactory base-course strength, compared with gradation floating and the change of degree of compaction.
