Brief Description:

The Texas APT program was established in 1995. The APT loading device used is the MLS machine which is a transportable linear device capable of applying six single or dual-tire bogies with tandem axles loaded up to a nominal 190KN (42,000lbs), at speeds up to 20km/h (12.5mph). The test pavement length is 11m (36ft) with optional transverse tracking over 0.6m (24 in.). Up to 8,800 axle loads can be applied in one hour. A fully enclosed environmental control chamber is used for temperature control. The device can be dismantled and reassembled in one day and can be jacked up to allow in situ testing. The device was successfully used for test sections on in-service highways.
