Cement concrete roads provide dustless and sanitary surface. Cement concrete roads does not develop corrugations and hence it grants noiseless surface. It can be designed more accurately for load distribution. Cement concrete roads is practically unaffected by weather and temperature.
cement concrete, Pst construction, Pe content, Pr repair, Te road operation in time (in years), Pstc = 1,8#183;Psta) As it can be seen from Fig. 3, the total cost of construction and maintenance of highways made from cement concrete (c), after 10 years of operation, is lower than for the roads with asphalt concrete (a). Thus, the use of
#0183;#32;Cement Concrete Roads: The roads having their wearing surface consisting of cement concrete (plane or reinforced) are known as cement concrete roads or concrete roads. These roads are types of rigid pavements and remain in serviceable condition under all weather conditions. Thus concrete roads are also considered as all weather roads.
Joints in Cement Concrete Roads 14th February 2019 0 By Malay Sautya Joints are provided in cement concrete road to allow expansion, contraction and warping of the slabs due to the variation in the temperature of slabs.
INTRODUCTION 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.
What is cement concrete road? A properly designed and constructed cement concrete road is a pathway designed to carry heavy traffic. It has a base level of one to Six feet (depending on the soil conditions) of sand, topped with one to three feet o...

A concrete pavement is a structure comprising of a layer of Portland cement concrete (base) which is usually supported by a subbase layer on the subgrade. The terminology used in Australia is illustrated in Figure1. Concrete pavements may be either unreinforced (plain) or reinforced depending on how the designer prefers to
Introduction This paper seeks to explore some of the benefits gained by using processed, quality assured fly ash in the construction of concrete roads. In the UK, as in many other countries throughout the world, the use of fly ash concrete in the construction of pavement quality concrete for use in roads and airport runways is well established.
#0183;#32;Concrete Roads: PQC, Methods of Construction and How it is Made! Introduction to Concrete Roads: Concrete roads fall under the category of high quality/superior type of roads built with cement concrete. These pavements may or may not be provided with subbase/base courses, and they may be constructed directly over a wellcompacted soil subgrade.
2) High Strength Concrete: It is better than regular concrete as it can withstand more pressure. In this mixture, the water to cement ratio is lowered. It is also important to choose an aggregate with extreme care as a weaker aggregate could affect the strength of the concrete.
volume roads do not fail in this manner, they do not require subbases to prevent subgrade pumping, In kilograms per cubic meter) of concrete, with a maximum watercement ratio as given in Table 2, will significantly increase freezethaw and sulfate resistance of the concrete pavement.
Concrete is one of the most versatile and durable construction materials that has been in use for centuries, in one form or the other. Present day concrete provides innumerable applications with very few limitations be it in buildings, roads, bridges, railways, or dams.
