Abstract
This invention provides a safety device for quickly arresting the movement of vehicles such as aeroplanes and motor cars by forming a retarding bed of crushable material adjacent to a vehicle track. A foam is formed from an aminoplast resin composition and layed down in a bed adjacent to the vehicle track where it is cured in situ to produce a non-resilient cured foam body having a compressive strength between 15 and 50 p.s.i. and a density from 0.25 to 10 pounds per cubic foot.
