ATS Rolling Thin Film Oven

March 13th, 2017

Applied Test Systems has been manufacturing custom furnaces and ovens since 1965, and entered into the bitumen / asphalt binder market in the early 1990’s with the introduction of Superpave! It only seems logical to expand our many years of industry and process heating knowledge into the creation of the Applied Test Systems Rolling Thin Film Oven, the RTFO Touch.

The NEW RTFO Touch from ATS has been designed to simulate short-term aging of asphalt binder according to ASTM D2872, AASHTO T240, EN 12607, Superpave, and California Test Method 346 test standards and now offers customizable options to accommodate a broad spectrum of users.

RTFO Touch Features

Double walled stainless steel oven capable of maintaining temperature of up to 220⁰C (428⁰F)
Precision NIST traceable Microprocessor -based Platinum RTD
NIST traceable digital flow meter
Heat-recovery time around 5 minutes after specimens are loaded

Dynamic Shear Rheometer

Industry standard Asphalt binder grade testing

Market proven worldwide, the Malvern DSR dynamic shear rheometer has been specifically designed to satisfy the demands of high throughput grade testing of Asphalt binders (bitumen), to AASHTO (American Association of State Highway and Transportation Officials) industry standards.

Overview

The Malvern DSR asphalt rheometer is proven as the benchmark system for Quality Control testing to industry standards in regulated markets worldwide.

Developed in close association with industry researchers to meet all instrument criteria and test protocols of AASHTO (American Association of State Highway and Transportation Officials) standards.
Compact, integrated unit designed specifically for ease of use and robustness in high throughput Asphalt binder (bitumen) test environments.
Air bearing and mechanical bearing options to provide robust and cost-effective measurement platforms for any industrial laboratory or remote field testing location.
Integrated fluid immersion cell specifically based on patented principle for temperature control of highly thermally-sensitive asphalt or bitumen samples.
Rapid thermal equilibration and elimination of thermal gradients in the sample - essential for consistent and reliable data, and optimized sample throughput.
Excellent temperature stability and accuracy, with a resolution of ± 0.01°C.
Rapid, robust manual gap set, with pre-set gaps for AASHTO tests for simplicity of use.
Active thermal mode to ensure constant gap is maintained for all temperature test points.
Plate measuring systems (both upper and lower plates) designed to comply with industry standards (AASHTO).
Dedicated AASHTO specification QC software package (TruGrade) available.
