Lab Equipment

Of the cracking tests gaining popularity for their correlation to field results, the Indirect Tensile Asphalt Cracking Test (IDEAL-CT) scores near the top of the class. If your department of transportation (DOT) requires you perform this test on your balanced mix designs (BMD) or other mixes, here’s how to do it.

There’s more happening in the world of quality control/quality assurance than finding the most expedient way to implement balanced mix design-favored testing protocol. Let’s take a look at what equipment manufacturers and lab service providers have to offer.

Preliminary testing with the mobile WLB 10 S laboratory plant from Wirtgen Groupenables foamed bitumen quality to be precisely determined in the lab prior to the start of construction by offering one-to-one simulation of the cold recycling process in the lab.
