Laboratory Equipment for Asphalt Concrete

Automatic Ultrasonic Cleaning Technology

The described system is a computer-controlled and operated machine via a touch panel, designed for the extraction and determination of binder content in Asphalt Concrete mixtures within a closed-loop system using non-flammable solvents. This machine complies with EN 12697/1, ASTM D 8159-2018, and AASHTO standards for Asphalt Concrete testing and analysis. It can be equipped to operate with solvents such as trichloroethylene, perchloroethylene, or dichloromethane. It allows processing up to 3.5 kg of Asphalt Concrete material, which is weighed and placed in a washing drum, then automatically cleaned using solvents and ultrasonic technology.

During the process, the aggregates remain in the washing drum, while the binder, solvents, and fines (filler) from the Asphalt Concrete are separated in a centrifuge and subsequently in a recovery still via distillation, allowing for solvent reuse. Two windows permit visual inspection of the recovery process. The aggregates and fines are automatically dried, enabling sieve analysis to be performed at the end of the cycle for Asphalt Concrete evaluation.

The machine is software-operated and allows for the programming of washing and drying cycle sequences for Asphalt Concrete samples. Its main advantages include a fast extraction time (35 to 45 minutes) and a significant reduction in environmental impact, with a solvent loss of less than 20 ml per extraction. It requires a continuous cooling water supply and approximately 20 L of stabilized solvent for operation.

The recycling kit (RC-Asphalt) includes observation windows for the recovery process, a sieve inlet for uncollected Asphalt Concrete components, and LED-equipped temperature limiters for distillation processes. It also features a connection for a rotary evaporator, utilizing solvents such as stabilized trichloroethylene (HI-TRI-SMG) or perchloroethylene for efficient Asphalt Concrete binder recovery and analysis.

What Our Clients Say

A team of professionals

“My experience with Strinso has greatly benefited the company through the timely delivery of measurement services and reports. I recommend Strinso because of their highly knowledgeable team of professionals and their cutting-edge equipment, which enable them to deliver high-quality results in pavement analysis.”

Reinel Leonardo Monroy Ibáñez

Project Director - Doble A Ingeniería S.A.S - Bogotá, Colombia

Specialized, High-Quality Consultancy

“We have worked with Strinso on the studies for 5G Concession highway projects; their advisory has consistently been specialized and high-quality, adding significant value to our pavement studies. They possess an expert team and their own equipment to execute and analyze the results of the necessary field work. A key recommendation: tender engineering projects are unique, as they are often executed within relatively short timeframes, during which many variations occur. These variations require great flexibility to be incorporated quickly. It is essential to keep the client's needs in mind when handling such tender projects.”
