Study Notes
Highway Development History
- Early Transport: Humans walked, used animals, and crude sleds for transportation.
- Ancient Roads: The invention of the wheel in Mesopotamia led to animal-drawn vehicles. Evidence of hard-surfaced roads dates back to 3500 BC.
- Ancient Structures: The Assyrian empire built roads around 1900 BC. The ancient civilizations of the Mediterranean island of Crete, as well as the Mayans, Aztecs, and Incas of Central South America, constructed roads.
- Roman Roads: The Roman Empire built a vast network of roads, many of which remain in use today.
Highway Engineering Pioneers
- Jerome Tresaguet (1716-1796): French engineer introduced new methods of constructing and maintaining stone roads in 1764.
- Thomas Telford (1757-1834): Scottish engineer improved upon Tresaguet's methods by using a foundation of stones and a flat subgrade with a slight crown for drainage.
- John Loudon McAdam: Scottish engineer developed the first modern roads using an inexpensive paving material of soil and stone aggregate called "macadam." He proved that massive foundations were unnecessary and that the native soil could support the road if protected from water and wear.
Highway Development Innovations
- Modern Road Construction: Modern roads are largely based on McAdam's methods with advancements in materials and construction techniques.
- Bituminous and Cement Concrete: The use of these materials has been a significant development in road construction.
- Equipment Advancements: Development of new equipment speeds up road construction.
- Local Materials: Laboratories test locally available materials for use in road building, resulting in cost-effective and durable pavements.
Early Transportation in the Philippines
- Early 1900s: Transportation relied heavily on trails, waterways, railroads, earth roads, and partially graveled roads.
- American Influence: The US government initiated the development of roadways in the Philippines to connect towns, cities, and provinces, introducing the widely accepted Macadam road type.
- Post World War II: After the war, the independent Philippine government continued repairing and constructing roads and bridges.
