The term 'Road Crew Supply' refers to the materials and equipment needed for road construction and maintenance. Two of the most important supplies are ASPHALT and TAR, which are used to create a smooth and durable surface for roads. ASPHALT is a seven-letter word and TAR is a three-letter word. ASPHALT is a mixture of aggregate and bitumen, while TAR is a dark, viscous liquid derived from coal or wood. Both ASPHALT and TAR are essential components of road construction and maintenance, providing a strong and durable surface for vehicles to travel on.
