Final Report on Road Test One-MD


Book Description

Tests were conducted on a 1.1-mi. section of portland- cement-concrete pavement near La Plata, Maryland, to determine the relative effects of four different axle loads on a concrete pavement. The loads employed were 18,000 lb. and 22,400 lb. on single axles, and 32,000 lb. and 44,800 lb. on tandem axles. There were four separate test sections with trucks selected for each section to obtain the highest practicable rate of acceleration between 10 and 40 mph. on the existing road profile. Controlled-traffic tests were conducted from June through December 1950, soil and strain tests made in 1951. The analyses of these data, which included 6,000 soil tests and 12,000 strain and deflection readings, were completed in April 1952.

Pavement Asset Management


Book Description

Comprehensive and practical, Pavement Asset Management provides an essential resource for educators, students and those in public agencies and consultancies who are directly responsible for managing road and airport pavements. The book is comprehensive in the integration of activities that go into having safe and cost-effective pavements using the best technologies and management processes available. This is accomplished in seven major parts, and 42 component chapters, ranging from the evolution of pavement management to date requirements to determining needs and priority programming of rehabilitation and maintenance, followed by structural design and economic analysis, implementation of pavement management systems, basic features of working systems and finally by a part on looking ahead. The most current methodologies and practical applications of managing pavements are described in this one-of-a-kind book. Real world up-to-date examples are provided, as well as an extensive list of references for each part.




Paving Our Ways


Book Description

Paving Our Ways covers the international history of road paving in an interesting, readable and technically accurate way. It provides an overview of the associated technologies in a historical context. It examines the earliest pavements in Egypt and Mesopotamia and then moves to North Africa, Crete, Greece and Italy, before a review of pavements used by the Romans in their magnificent road system. After its empire collapsed, Roman pavements fell into ruin. The slow recovery of pavements in Europe began in France and then in England. The work of Trésaguet, Telford and McAdam is examined. Asphalt and concrete slowly improved as paving materials in the second part of the 19th century. Major advances occurred in the 20th century with the availability of powerful machinery, pneumatic tyres and bitumen. The advances needed to bring pavements to their current development are explored, as are the tools for financing, constructing, managing and maintaining pavements. The book should appeal to those interested in road paving, and in the history of engineering and transport. It can also serve as a text for courses in engineering history.
