研究了在二灰中加入磷石膏后对二灰以及二灰稳定粒料的强度、强度发展、水稳性、抗冲刷性的影响,结果表明:磷石膏对二灰类路面基层材料有显著的改性作用,磷石膏改性二灰早期强度大幅度提高,后期强度发展稳定,水稳性特别是早期水稳性显著提高,改性后的二灰稳定基层的抗冲刷性介于二灰和水泥稳定基层之间,和二灰相比有大幅度提高,是一种性能良好的路面基层材料。
The effects of phosphogypsum on the strength, strength development, water stability and scour resistance of lime-fly ash and lime-flyash stabilized pellets were studied. The results showed that phosphogypsum had significant The early stage strength of phosphogypsum modified fly ash improved greatly, the late stage strength developed steadily, the water stability, especially the early water stability increased significantly. The anti-scourability of modified lime-flyash stabilized base was between two ash and Between the cement stabilized grassroots, and ash has greatly increased, is a good performance of the pavement base material.
