Study Notes
Definition and Purpose of Highways
- Major roads designed for high-speed, efficient vehicle movement over long distances.
- Typically feature multiple lanes to accommodate large traffic volumes.
- Connect cities, towns, and regions, facilitating both local and interstate travel.
Historical Context
- Early roads (circa 3500 BC) were built for military movement and trade.
- Romans innovated with cement, constructing roads that lasted for 2000 years.
Construction Techniques in History
- Summum Dursum: Large stone slabs used in early roads.
- Nucleus: Layer made from small gravel and coarse sand.
- Rudus: Thick layer of concrete made from stone.
- Statumen: Layer of stones, each at least 2 inches in size.
Pioneers of Road Development
- Jerome Tresaguet: Introduced modern road building techniques; known as the father of modern road construction.
- Thomas Telford: Notable Scottish engineer; contributed significantly to road design.
- John Loudon McAdam: Developed the macadam road, leading to widespread acceptance in construction.
- Eli Blake: Invented the first stone crusher in 1858, enhancing road material processing.
Highway Development in the Philippines
- Pre-1900s: No formal highways; transport relied on trails and waterways.
- Post World War II: Emphasis on road development aided by Japanese and US financial support.
- 20 Years After WWII: Major highways and expressways constructed with World Bank and IMF assistance.
- 1950s-1980s: Road construction prioritized during the automobile age with the slogan "The nation is on wheels."
- 1980s to Present: Continued development along with technical advancements in highway construction.
Common Functional Categories of Highways
- Freeway: Designed for high-speed motor vehicles with speed limits of 120 km/h or more; features complete or partial separation from other roads.
- Expressway: Handles high-speed traffic (≥100 km/h) with controlled access and no parking; interchanged distances based on specific formulas.
- Arterial Road: Supports traffic mobility for various transportation means; maximum speed between 80-100 km/h.
- Boulevard: Separate roadways for different traffic streams with controlled intersections; maximum speed between 70-80 km/h.
- Collector/Minor Roads: Allows for vehicle and pedestrian traffic with designated parking; speed limit of 30-50 km/h.
- Local Road: Single travel way catering to all vehicles with unlimited parking; maximum speed of 15 km/h.
