The Asphalt Content Ignition Furnace is a laboratory testing instrument designed to determine the asphalt (bitumen) content in asphalt mixtures using the ignition method. By heating the sample at high temperature, the asphalt binder is burned off while the remaining aggregate mass is measured to calculate accurate binder content. This equipment provides fast, reliable, and precise results, making it widely used in highway construction, pavement engineering, and quality control laboratories for asphalt mixture analysis.

Asphalt Binder Content Ignition Furnace

Model:TD735-2

I.Product Introduction

The TD735-2 Asphalt Content Ignition Furnace is developed and manufactured by Hebei Tianqixingzi Inspection Equipment Co.,Ltd.. It is a high-performance laboratory instrument designed for determining the asphalt (bitumen) content in asphalt mixtures by the ignition method.

The equipment removes asphalt binder from the mixture through high-temperature combustion, and the asphalt content is calculated by measuring the mass difference before and after ignition. It is widely used in highway engineering, pavement construction, and materials testing laboratories.

II.Standards Compliance

The equipment can meet or refer to international test standards, including:

ASTM International ASTM D6307

AASHTO AASHTO T308

European Committee for Standardization EN 12697-39

JTG 3410-2025

III.Technical Parameters

1.Working chamber size: 350 mm (L) × 440 mm (W) × 330 mm (H)

2.Power supply: 380V ±10%, three-phase (star connection), current ≤ 20A

3.Balance capacity: 10 kg

Balance resolution: 0.1 g

4.Maximum furnace temperature: 800°C

5.Maximum sample weight: 3500 g

Recommended sample weight: 1000–1500 g

6.Stability coefficient: 0.1%

IV.Working Principle

The ignition method is based on heating the asphalt mixture in a high-temperature chamber (up to 800°C). The asphalt binder is completely burned off, while the mineral aggregate remains. The loss of mass is automatically calculated to determine the asphalt content accurately and efficiently.
