This document provides an overview of the history and development of highway engineering. It discusses early Roman roads which had large stone foundations and slopes of 1 in 45. It describes the Tresaguet and Metcaff methods which further improved road design by adding larger kerbs and constructing 290kms of road. The Macadam method is introduced, developed by John Macadam, which used broken stones for stronger foundations and better compaction and drainage. Highway development in India is then summarized, outlining key committees, acts, and plans from the 1920s to 2000s that classified roads and set construction targets to expand the network.

Highway Engineering

3. Highway Engineering
• transportation - through road - more flexible
• history
By foot - used animals - wheels invented - proper path needed.
• Roman roads
large depth of road (.75m - 1.2m) - large stones (10-20cm) on foundation and top
surface - lime concrete as filling material - no slopes - not economical.
• Tresaguet method
Large stones embedded in subgrade - slope rovided (1 in 45) - large kerb provided.
• Metcaff method
290kms of road constructed
• Telford method
large stones used in subgrade but, placed to provide slope (1 in 45)

4. • Macadam Method of construction
John Macadam - contributions in 1827
1) no need of stronger foundation - load intensity reduces - broken stones
2) Subgrade drainage & compaction
modified forms - Water Bound Macadam
Penetration Macdam
Bituminous Macadam
