HIGHWAY BUILDERS

A British import containing full-color drawings and brief descriptions of ten types of heavy machinery used in the construction of a road. Inattention to detail all but eliminates its usefulness: Measurements are given in tonnes; some material is illogically placed (the mobile crane is grouped with earthmoving equipment); inaccurate labels, such as the names of various lights on the dump truck, mar the highly realistic illustrations; and asphalt is the only type of finished surface discussed, even though most US highways are paved with concrete. One entry in the glossary, diesel engine, is out of alphabetical order.
