The Experimental Research on the Material Properties and Road Performance of the Fly Ash Blended with Stabilizing Agent JNS-2

The reinforcing agent for the fly ash (JNS-2 Model) from San Xin Construction and Technology Corporation in Zhenjiang City was used to stabilize the fly ash. Then series of tests on the road performance of JNS-2 stabilizing fly ash were conducted systematically. First, tests about the optimal proportion of stabilizing fly ash were carried out, then the road performance tests including the unconfined compressive strength, indirect tensile strength, frost stability, drying shrinkage, temperature shrinkage, fatigue strength were conducted for JNS-2 stabilizing fly ash; at the same time, its test results were compared to those of lime fly ash gravel and lime fly ash macadam to determine its control parameters of road performance. The results from the experimental investigation showed that JNS-2 stabilizing fly ash had higher strength and resilience modulus, better frost stability and anti-fatigue performance and lower shrinkage. The research indicates that JNS-2 stabilizing fly ash has potential to be used as a pavement base layer material in similar applications and can be used as a sub-base material in highway pavements.
