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.
