Study on correlation between viscosity of emulsified asphalt mortar and suspended sand capacity
The study of the correlation between the viscosity of emulsified asphalt mortar and suspended sand capacity can provide a scientific foundation for a good homogeneity and fluidity of freshly mixed emulsified asphalt mortar with sandy fog seal layer at the same time.The viscosity test and suspended sand test of emulsified asphalt mortar are used to evaluate the influence of asphalt penetration grade,as well as the quantity and type of thickener on viscosity and suspended sand capacity of emulsified asphalt mortar.The correlation between viscosity and suspended sand capacity is established according to the fitting parameters of viscosity curve and settling curve.The results show that with the increase of penetration grade of asphalt,the viscosity of mortar decreases and the ability of suspended sand decreases.With the increase of the concentration of various thickeners,the viscosity of emulsified asphalt mortar and the ability of suspended sand are increased.For different types of thickeners,under the same cindition,the viscosity increasing effect is organic thickener,diatomaceous earth and silica-aluminate in descending order,but the suspended sand capacity ranked in the reverse order.According to the fitting results,the correlation between the viscosity parameter and the settling rate is analyzed,both show the same growth,and it is determined that the correlation between the viscosity and the suspended sand capacity is positively correlated.
