Disadvantages of Cement Concrete Road. 1. The initial cost of construction is very high. 2. They require skilled supervision and labour for their construction. 3. They are liable to crack and warp due to temperature variations. 4. They become noisy under iron-tyred traffic. 5. They are less resilient than bituminous or WBM roads. 6.
Context Sensitive SolutionsContext Sensitive Solutions These finishes have been selected based on their continued use in WSDOT construction projects. Aesthetic features are for the communityyy and corridor roadway sides, depending on the project. The State Bridge and Structures Architect is required to approve concrete surface treatments.
Proper design and construction are absolutely necessary if the pavement is to perform. Must be uniform throughout pavements life. Poor subgradesubbase preparation can not be overcome with thickness. Any concrete pavement, built of any thickness, will have problems on a poorly designed and constructed subgrade or subbase.

International Series of Monographs in Civil Engineering, Volume 4 Concrete in Highway Engineering focuses on the design and construction of highways. The book first offers information on concrete as a material. Cement, aggregates, water, concrete mixes, and curing concrete are then explained. The text examines the design of pavements.
The Durability of road structures depends on the quality of its maintenance amp minor renovations. Maintenance keeps the roadway safe, provides good driving conditions amp prolongs the life of the pavement, thus protecting the road investment. Currently in India more than 2000 km of concrete road is in the operation since last few years.
