The Laboratory Reflux Asphalt Extractor efficiently separates asphalt binder from aggregates using a controlled reflux process. It provides precise measurements of asphalt content, making it an essential tool for laboratory testing, quality control, and asphalt mixture research.

Reflux Asphalt Extractor

Model:TDHY-II

I.Product Introduction

This method specifies a test method for determining the asphalt content in asphalt mixtures using a reflux extraction apparatus.

This method is applicable to the testing of asphalt content in asphalt pavement construction to assess construction quality,and is also suitable for testing asphalt content in old road surveys.However,for coal tar pavements,original measurement data of the free carbon content of the coal tar pitch is required.

Apparatus and Materials:The reflux asphalt extractor consists of a water condenser,extraction cylinder,copper mesh sieve,outer sleeve,and heat source.
