Pavetest’s new thermal cracking test

Matest subsidiary Pavetest launched its new thermal stress restrained specimen test (TSRST) machine, the TSRST-Multi, at bauma. Designed for tests set down in the AASHTO TP10-93 and EN 12697-46 standards, the machine can test three specimens simultaneously inside a temperature-controlled cabinet which can vary in increments of 10 degrees between - 40 and +40 degrees C. “We decided to come up with a flexible approach where each station can test statically or dynamically. And you can have any combination,”

282 Matest subsidiary 7955 Pavetest launched its new thermal stress restrained specimen test (TSRST) machine, the TSRST-Multi, at bauma. Designed for tests set down in the AASHTO TP10-93 and EN 12697-46 standards, the machine can test three specimens simultaneously inside a temperature-controlled cabinet which can vary in increments of 10 degrees between - 40 and +40 degrees C.

“We decided to come up with a flexible approach where each station can test statically or dynamically. And you can have any combination,” said Pavetest MD Con Sinadinos. “It’s been in development for six months.”

Sinadinos highlighted a new approach to the design of the machine, where all the refrigeration elements are isolated within one detachable unit. This means transportation costs can be lower, because certain units are not so tall, and it makes maintenance easier, he said.

Pavetest has developed its control and data acquisition system so that eight channels rather than 16 are needed, which means that a smaller control unit can be integrated into the machine. “Normally you see a mass of wires coming out of these machines. Here they are all hidden out of the way,” said Sinadinos.

    Quicker, better, more cost effective materials testing - Kristina Smith writes. Most developments in materials testing technology involve updating and upgrading existing machines, either to meet changes to standards or to satisfy new needs in the market. And occasionally, a manufacturer will come up with something completely new. PUMA - the precision unbound materials analyser - falls into the latter category. It has been developed by Cooper Research Technology and Nottingham Transportation Engineering Cen

    Emerging markets, such as North and East Africa, are developing an appetite for materials testing equipment, but suppliers need to provide expertise and training as well as a broad range of machines, as Kristina Smith finds out Asking what sort of testing equipment is required for Africa is a little bit like asking what sort of food Europeans like to eat. The answer is that requirements vary enormously from the most basic and ancient of tests to the very cutting edge of dynamic testing. “You have some

    Today’s highways require high performance materials, and this means rigorous testing as Patrick Smith reports Highways are under greater pressure than ever today and asphalts have to grant high performances in order to withstand traffic and meet the standards. Studying the plastic permanent deformations in hot mix asphalt (HMA) is very important to obtain useful information for mix designers as an appropriate mix design will reduce the formation of unevenness on road surface. To investigate the effect of mi
