Asphalt Road Construction is one of the most common terms in the road construction. However, the versatility of the Asphalt is beyond the road construction. Asphalt Road Construction is the technique of construction using aggregates, binders and fillers. These are the primary resources for the construction technique and it is used for construction on any surface.
It is important to understand the composition of any construction style to know more about it. Aggregate, Binders and Filler are used for Asphalt Construction. The aggregates are the mixture of stones, rocks, slags, pebbles and others. The aggregate is mixture and hence need binders to hold them. Bitumen is the most common binders used for the Asphalt Road Construction. The fillers are used to complete the construction process. The resources however differ as per the requirements. Different road conditions have different requirements. The traffic pressure and the conditions want specific strength on the road. To make sure that the road sustains varying pressure exerted, the composition and the mixture is varied. However, the primary resources remain unchanged.
Asphalt Road Construction is a different style and executed in different style. The construction is primarily made above the formation level. The pavement is prepared above the level with the bituminous aggregate and fillers. There is a reason for the style. If the pavement is applied above the formation level then the aggregate gets spread out. It henceforth gives the enough ability to sustain the traffic pressure. This is one of the construction style that gives strong and durable road construction.
Types of Asphalt Road Construction
Depending on the various roads Asphalt road construction differs. However, the difference is only in the composition type and how they are dealt. The types of the Asphalt construction is broadly classified into three different mixtures.
This Asphalt Road Construction is generally performed with the mixture made in temperature between 90-180 degree centigrade. Porus Asphalt, Mastic Asphalt, Stone Mastic Asphalt, Soft Asphalt, Asphalt Concrete, Asphalt Concrete with thin layers, Asphalt Concrete with thick layers, Double Porus Asphalt Construction are most common and frequently seen different kinds of Asphalt Road Construction. All the types of Asphalt Construction however is dependent on the material and how these have been used. The engineers know the composition required for the particular conditions. This is followed for highly trafficked roads.
The warm mixes are performed in the temperature in the range of 30 to 40 degree centigrade. The less temperature makes the construction faster. As far as strength is concerned it is also highly durable and used for moderate to high traffic roads.
This is the third type of mix that is used for the Asphalt Road Construction. The aggregate in this case is not heated at all. Multiple compaction generally used for the mixing of the aggregate. The frequent compaction provide the required strength to the road. However, this construction is used for lightly trafficked roads.
Asphalt Road Construction is one of the most used construction style used for the roads. It is also highly durable and reliable construction.
