Life-cycle Cost

The life-cycle cost of a road includes the money spent on initial construction of a road, maintenance over its lifetime, and the costs to users for their delays during maintenance and reconstruction Life-cycle costs of hot-mix asphalt pavements are significantly lower than those of Portland cement concrete pavements.

Asphalt Pavement Construction

At one time it was thought that a prime coat was an essential element of good pavement construction However, in recent years some engineers have eliminated the use of a prime, especially when asphalt layer(s) (surface and/or base) is 4 inches or more in thickness.

Asphalt vs Bitumen

Bitumen is cheaper, When you compare the price between bitumen and asphalt, bitumen is a clear winner Bitumen is cheaper to install and if you are planning to resurface a road with low volumes of traffic, bitumen can be a good investment However, asphalt is the most cost-effective.

The benefits of modified asphalts

The benefits of modified asphalts , agencies estimate that an additional four to six years of pavement life from a pavement constructed using a modified asphalt binder is a reasonable expectation , The AASHO Road Test (1958-1962) is still widely used for pavement design That research was based on a legal load limit of 73,280 pounds.

Bituminous Surface Treatments

Jul 19, 2011· Bituminous surface treatments (BST) refer to a range of techniques that can be used to create a stand-alone drivable surface on a low volume road, or rehabilitate an existing pavement Usually, the term is used to describe a seal coat or chip seal, which is constructed by spraying a layer of emulsified asphalt, and placing a layer of aggregate on top BSTs can be applied directly to a base.

Asphalt vs Concrete Driveways

Ignoring any maintenance costs, asphalt is generally much cheaper to install than concrete On average, the cost per square foot for asphalt will run between $250 to $400 Fluctuations in crude oil prices can cause fluctuations in asphalt prices but the price will remain around this range.

Why are they Replacing All the Concrete Roads with Asphalt
