集料特性对集料改性乳化沥青胶浆黏度的影响
Effects of aggregate characteristics on viscosity of aggregate-modified emulsified asphalt mortar
摘要
Abstract
Limestone, basalt and granite fine aggregates with different sizes were selected to prepare aggregate-modified emulsified asphalt mortar.The chemical composition, specific surface areas, the surface charges of aggregates and the rotational viscosities of modified-emulsified asphalt mortars were measured.The effect laws of aggregate characteristics on the viscosity of aggregate-modified emulsified asphalt mortar were analyzed.The results show that the mortar viscosity increases and tends to stabilize during the demulsification of modified emulsified asphalt.The stabilizing time of acidic aggregates mortar is the shortest.For the mortars mixed with the aggregates with the same li-thology, the larger the specific surface area of aggregates, the larger the initial viscosity and the shorter the stabilizing time.For the mortars mixed with the aggregates with the same specific surface area, the bigger the ζpotential value on aggregate surface, the smaller the initial viscosity and the longer the stabilizing time.The shorter stabilizing time of mortar viscosity implies a faster demulsifi-cation speed of modified emulsified asphalt and the time available for construction would be shorter.关键词
