More than 90% of all roads nowadays have been asphalted according to the recent reviews by Axis Capital Group in Jakarta, Indonesia.

Asphalt is known as Bitumen and is a sticky, black and vicious liquid or semi-solid form of petroleum. In addition to being smooth, durable, safe, and quiet, asphalt is the most versatile pavement material. Pavement structures can be designed to handle any load, from passenger cars to heavy trucks. Surface mixes can be customized to absorb noise, to reduce splash and spray during rainstorms, and even to help treat rain water.

Perpetual Pavement

What it is

Perpetual pavement main concept is for it to last, last and last in a very very very very long time, hence, the name. Perpetual Pavement combines the well-documented smoothness and safety advantages of asphalt with an advanced, multi-layer paving design process that with routine maintenance extends the useful life of a roadway.

Perpetual pavement ranges from the thinnest and thickest asphalt. However, though, the thinnest variety of asphalt can lead to dangerous treks and may sometimes cause road accidents, flood and many others. Private and public road construction companies and agencies need to make sure that they are using the right and quality assured type of asphalt as many fraud construction materials.

How it works

Perpetual pavements should use multiple layers of durable asphalt to produce smooth, sage, long lasting road which most of the time reduces noise. The pavement design begins with a strong, yet flexible bottom layer that resists tensile strain caused by traffic, and thus stops cracks from forming in the bottom of the pavement.

A Perpetual Pavement provides a durable, safe, smooth, long-lasting roadway without expensive, time-consuming, traffic-disrupting reconstruction or major repair.

Major advantages

When scheduled surface restoration is performed, Perpetual Pavements can be maintained easily and cost-effectively without removing the road structure for reconstruction, saving time and money while keeping motorists happy.

Asphalt is even recyclable, providing further cost savings and environmental benefits. United States of America saves $1.6 billion in recycling asphalt every year.

Asphalt has a proven safety record as a driving surface, offering stronger visual contrast with center stripes and other markings. Additional advantages can include reduced noise, reduced splash and spray, and greater skid resistance.
