HOW TO USE THIS MANUAL 

 
Before using the 

Troxler NTO (New Technology Oven) Asphalt 

Content Ignition Oven

 or “oven,” 

read this manual carefully. 

Of 

particular importance is the safety information in Chapter 2. 

Do not 

attempt to operate the oven before reading this manual and the 
safety warnings posted on the unit. Troxler stresses that 

the user is 

solely responsible 

for ensuring the safe use of the oven. Neither the 

manufacturer, its subsidiary, distributors, or representatives can 
assume responsibility for any mishaps, damage, or personal injury 
that may occur from failure to observe the safety warnings in this 
manual and posted on the unit. 
 
The oven allows measurement of the asphalt content of asphalt 
mixes. After ignition testing, the remaining aggregates may be used 
as sample for gradation measurements. The Troxler NTO

 Manual of 

Operation and Instruction 

describes the installation, setup, and 

operation of the system.
