Introduction to Highway Engineering Presented By: Juniffen I. Tacadena
What is Highway Engineering? Highway Engineering is a specialized field within the discipline of Transportation Engineering that involves the planning, design, construction, operation, and maintenance of roads, bridges, and tunnels to ensure safe and effective transportation of people and goods. Highway Engineering considers all aspects related to the design of the roads themselves, as well as how pedestrians are managed. Highway Engineering has expanded to include a new area of focus for this discipline on the implementation and use of intelligent transport systems that will eventually revolutionize the way humans travel day to day.
What is Road Building? Road Building is defined as the art and science of construction, rehabilitation and maintenance of existing roadway facilities. It is a continuous process of study and research, for up to this time there is no definite solution yet formulated to avert road failures.
Brief History of Roads Early roads with hard surfaces were found in the land of Mesopotamia. These roads were constructed as early as 3, 500 B.C. These early road systems were constructed primarily for the following purposes: 1. For the movement of armies in their conquest and for defense against invasion.
2. For transport of food and trade of goods between neighboring towns and cities.
Who introduces the first Concrete Pavement? The Romans, who discovered cement, expanded their vast empire through extensive road networks radiating in many directions from the capital city of Rome. Many of the roads built by the Romans still exist after 2,000 years.
Brief History of Roads In 1700s, Jerome Tresaguet, French Engineer introduces new methods and maintenance of stone roads by improving the crown, the drainage and the grade of the road. He was accredited as the “Father of Modern Road Building”. England followed the ongoing highway development started by France. The Macadam road concept named after John Louden Mac Adam, a Scottish Engineer, was developed and widely accepted.
Highway in the Philippines In the 1900s, transportation in the Philippines depends mainly on trails, waterways, railroads, earth roads and partially graveled roads/macadam roads. The American government initiated the development of roadways in the country connecting towns, cities and provinces. After the second World War, the government continued the rehabilitation and construction of roads and bridges through war damages paid by the Japanese government. Others coming from financial grants by the US government. 50 years later , major highways and expressways were constructed through the financial assistance and loans from foreign banks.
Highway in the Philippines Statistics revealed that more than 80,000 brand new vehicles were added to their lists every year. The DPWH must open 400 kilometers new roads every year. With this statistics, traffic problems are expected to worsen year after year. The year 1960-1980 was considered an automobile age. It was during this decade that road construction becomes a matter of priority of the government. Today, the government is still on progress of developing our road networks through its “Build, Build, Build” Program.

Planning Difficulties Highway planners are confronted with problems categorized as: 1.
Financial
2.
Political
3.
technical
Financial – Appropriations of funds for road constructions and maintenance, meet severe difficulties that sometimes, highway development plans are shelves temporarily for lack of funds.
Planning Difficulties Political – comprehensive road development plans that are carefully studied by technical experts are twisted, or flexed down by political muscles, to suit political interests. Roads and highway plans were either deferred, amended or realigned for political reasons.
Politicians now control DPWH projects as their source of political funds. Highway District Engineers qualification is simply subservience to the politicians. Listing of projects given to the district engineer has the corresponding name of favored contractors.
Planning Difficulties Technical – as a consequence, public confidence tremendously eroded, not only in the government’s ability to abate these problems, but also the proficiency of the technical men to offer solutions.
