Bitumen-based LASDs can be applied to trunk exteriors, floor pans, dash panels and other areas on cars prone to vibration and high levels of noise. Alternative sources of raw material are being researched, such as the production of synthetic asphalt from the liquefaction of sewage sludge. The different grades produced for suited applications are distinguished by two numbers to indicate the mid points of their softening point and penetration ranges. The Pitch Lake on the island of Trinidad was the first large commercial source, but natural sources have since declined in importance as petroleum became the major source.
