Mechanical Properties of Road Base with Roadbood EN-1 - 岩土工程灾害研究实验室(晏长根)

In order to offer theory base for the widely use of Roadbood EN-1 soil firming agent in road base, triaxial shearing tests are performed on road base consolidated with Roadbood EN-1 soil firming agent, cement and lime to analyze its mechanical properties. Stress-straining curve, peak strength, remnant strength, elastic modulus and shearing strength of road base consolidated with Roadbood EN-1 soil firming agent, cement and lime under different ambient pressures are measured through triaxial shearing test. The conclusions are peak strength, remnant strength and peak straining have straight line relationship with ambient pressure. Its destruction procedure can be explained with impairment. The stress-strain relation curve also indicated that Duncan-Chang Model could not be applied to road base consolidated with Roadbood EN-1 soil firming agent, cement and lime, while the modified Saenz Formula could be used to describe the stress-strain relation of it,and good agreement was obtained.
