Rigid Pavement

Cast in-situ concrete generally proposed for roads with a design traffic loading of 5 x 10⁶ heavy vehicle axle groups (HVAG) or more. Since 2000 the Public Works Department of Indonesia has been carrying out road rehabilitation and or road betterment using concrete pavement technology. Furthermore, concrete pavements have a number of specific applications, even though they are second to asphalt pavements in terms of current popularity. Besides, asphalt is a rapidly depleting resource, which might mean that concrete is the chief material for the future. However, concrete pavements have their drawbacks, such as high construction cost, low tensile strength, and significant contribution to global carbon-di-oxide emissions.

Concrete Pavement was chosen as an alternative for various reasons, including the roads in the area being frequently flooded, the road network in the industrial area experiencing heavy traffic, weak subgrade, and the asphalt roads being frequently damaged. Generally the principal types of cementitious concrete pavements are:

• Jointed Plain (unreinforced) Concrete Pavements (PCP)
• Jointed Reinforced Concrete Pavements (JRCP)
• Continuously Reinforced Concrete Pavements (CRCP)
• Steel Fibre Reinforced Concrete Pavements (SFCP).

PT. Harap Panjang  has built a hundreds of kilometers of concrete pavements of various types on national roads and industrial areas in Riau and Batam Island. Below are PT. Harap Panjang concrete batching plant facilities and construction activities.
