5.1 The CPL test is intended as a performance test to quantify the benefits of geosynthetics in pavement structures, as recommended by AASHTO R 50-09. Performance is predominantly defined in terms of S-TBR. 5.2 The CPL test is a laboratory test used to accelerate rutting in a roadway cross section...
This recommended practice contains dimensions and tolerances for spindles in the interface area. Interfacing components include axle spindle, spindle threads, bearing cones, bearing spacer, seal, and wheel hub. This recommended practice is intended for axles commonly used on Class 7...
4.1 An electrical pulse is applied to a piezoelectric transducer which converts electrical to mechanical energy. In the angle-beam search unit, the piezoelectric element is generally a thickness expander which creates compressions and rarefactions. This longitudinal (compressional) wave travels...
This SAE Recommended Practice covers passive torque biasing axle and center differentials used in passenger car and light truck applications. Differentials are of the bevel gear, helical gear, and planetary types, although other configurations are possible.
Introduction Note: Nothing in this standard supercedes applicable laws and regulations. Note: In the event of conflict between the English and domestic language, the English language shall take precedence. Purpose. To demonstrate compliance to Federal Motor Vehicle Safety Standard (FMVSS) 126...
This handbook is applicable to all new axle counter installations and to alterations at existing axle counter installations. The handbook is based on multi-section axle counters, however the same principles may be applied to other configurations. It is recognised that...
Purpose This standard defines requirements and provides guidance to those involved in data preparation for axle counter systems used on Network Rail managed infrastructure that are configured by geographic data. This includes the requirements to make sure data design is verified and that...

The scope of this procedure is that of providing a method for presenting calculations in support of a safety case for the operation of electric trains over TI 21 track circuits. All components relevant to TI 21 track circuits are considered. The document only considers double rail...
ESDU 90035 provides methods for estimating the drag experienced by aircraft tyres running in a layer of water or slush (with specific gravity down to 0.8) on a runway. Configurations covered are single tyre, twin-tyres (side-by- side), twin tyres in tandem, dual-tandem tyres (two pairs of...
