Material Properties Analysis of Acid-alkali Resistance Geosynthetics for Highway

摘要

In this paper,the engineering application characteristics for polypropylene filament geotextiles have been explored and analyzed.Besides,test about physical,chemical and mechanical properties has been conducted and conclusions have been drawn as below:engineering application characteristics for polypropylene geotextiles are good and corresponding physical parameters are excellent,especially good tensile property.The ageing resistance is outstanding,while breaking strength and elongation at break after aging test remain and show no obvious change.In addition,due to excellent acid and alkali resistant properties,the material can be applied to bituminous pavement and cement concrete pavement.
