Asphalt Concrete

Road pavement is very important to make vehicle, pedestrian as well as heavy machinery to mobilize on top of it with higher security. The properly paved road can act as decoration, practical sustainable movement support to promote longevity of the wheel, vehicle's body, passengers, foot of human as well as stability. Of course, many villages are still yet to develop the right pavement due to the budget in many states of the third world or developing countries. Anyhow, if a financial resource is not really an issue to the government with stable tax and other incomes from the domestic production, a healthy amount of infrastructure's part for the government will fork out the necessary working value for road paving.

The coverage of roads shall be as wide as possible to make sure citizen enjoy what they have paid off in term of income tax, sales & services tax or any specific taxes such as imported goods, stamp duty, alcohol or cigarette tax or more to the government tax department. The road is also an essential defence to any nation as tanks, troops or any armoured vehicles can move smoothly and promptly when in crisis. Definitely, police, ambulance and fire brigade those important team can also mobilize within borders of states, cities and towns quicker from a point to another point for greatest service to people. Transportation of goods, trading, logistics, construction materials as well as people can also be achieved at efficient cost.

There are plenty of types for classifying the road and pavement works and materials, but the majority of the road routes can be categorized into several ranges from its collectors, interstates, local roads to other arterial. There are main differences among the definition of pavement and road, but yet both are installed for the sake of places travelling, with the surfacing of either concrete road with modern materials or designs or with the traditional asphalt that is very popular applied on the highway of a long journey. They can be seen in urban and rural areas, for both directions to let vehicles speed without worry the structural strength. It can accommodate loads of both dynamic, static as well as other potential impacts.

At the meantime, we have seen pavements are also further divided into 3 classified kinds, from CRCP, JRCP and JPCP. Continuously reinforced concrete pavement (CRCP) is safely engineered with enough reinforced steel (roughly 0.6 to 0.7% through the cross-sectional area), that allows cracking to be holding together. Additionally, Jointed reinforced concrete pavements (JRCP) is applying contraction joints as well as reinforcing steel to make crack control, many of the times will have distributed steel (or also addressed as steel mesh reinforcement). Last but not least, would be the Jointed plain concrete pavement (JPCP) which put contraction joints for crack controls without any steel reinforced.

In term of pavement, flexible pavement is where the quite common type for surfacing, as it will be bituminous or also called as the common "asphalt" by most road contractors in Malaysia. This paving method has high flexibility as it can compromise with bending as well as deflects from its structural perspective. Traffic loads that are terrible could be compromised if the installation of flexible pavement to the road, from the highway to rural areas that allow heavy equipment, construction materials transportation and long trailers. Of course, all the restriction and road rules have been set by authorities after considering several factors, from the township development to pollution caused within the cities or more.

Rigid is another surfacing option backed up by the famous and most demanding materials in the building sector, the Portland cement concrete, this is rigid because of the compacted high-density concrete properties. Concrete needs this characteristic for its natural application which is also the originally developed purpose for the main goal to serve the construction industry. Further to the point, the concrete road has its own benefits such as safety, durability, lower wear and tear maintenance due to defects such as cracking, rutting, texture strips and potholes caused by flexible surface. Asphalt concrete pavement is basically used in combination of 5% minimal of asphalt cement with remaining comprises of stone, gravel and sand (also categorized as aggregates).
