4 Ways Asphalt Paving in Colorado Helps the Community

Asphalt paving is a vital part of the transportation infrastructure for Colorado. This type of pavement provides a safe, cost-effective and environmental friendly for the roads, bridges and parking areas. It plays a significant role in the Colorado community. Asphalt pavements is a combination of aggregates of stone, gravel or sand that are bound together using some asphalt cement, which is derived from crude oil.

A large percentage (94%) of American roads and highways are paved with asphalt. Construction and maintenance of these smooth asphalt pavements is cost-effective, eco-friendly, and completely recyclable. They offer a safe and long-lasting surface for all types of transportation modes such as foot trails, bike trails, roads and airport runways.

Some benefits of asphalt paving are:

1. Quieter Roads

Noise pollution is everywhere. One of the best ways to lower road noise is to deal with the issue at its source. By using asphalt pavements on roadways, noise in residential areas and businesses can be lowered significantly. Stone Matrix Asphalt can reduce road noise by 3-5 dB(A). Using asphalt to combat highway noise is even more effective than noise barrier walls.

2. Recyclable

Asphalt pavement and processing facilities have very low carbon footprint. Asphalt Pavement Alliance says that production of asphalt pavements emits less greenhouse gases compared to other concrete pavements. Asphalt pavements are highly recycled in America. 100 million tonnes of this type of pavements are reclaimed every year, and out of that, more than 95 percent is recycled or reused, thus saving the taxpayers money and less use of landfills.

Sustainability is very important in today’s society. Asphalt can be used over and over again, like an infinite life cycle. This one of the biggest reasons why asphalt is popularly used across the country. Most companies strive to use environment friendly materials; the recyclable nature of asphalt makes it a great product.

3. Create new jobs

A career in the asphalt industry means job security. Road construction is always happening in Colorado; new roads are being installed while existing roads require regular maintenance to enhance safety. From repairing potholes, to filling cracks, asphalt contractors are always busy trying to keep the Colorado roads clear, smooth and safer for drivers. Furthermore, construction of new business buildings means a need for parking lots installation as well as regular maintenance, which means job security in this field is great.

The asphalt pavement industry offers: local jobs that are usually pay well and last for long, heightened community transport infrastructure, improved standards of living for the local people, eco-friendly products, and economic development.

4. Asphalt is great for winter roads

Winter can be hard on pavements; the freezing, thawing, deicers, plowing and the immense weight of plow trucks contribute more to the damaging effects of the cold weather. However, some pavements can hold up better than other during this season.

Extreme winter weather can ruin paved surfaces. Asphalt pavement is not only quick to install, but is resistant to harsh weather too. Asphalt roadways can be able to withstand cold temperatures during weather in both the low traffic and high traffic areas.

Hot-mix asphalt is the best when it comes to ensuring that the roadways are free of potholes and cracks during winter. It is asphalt pavement that is poured immediately after mixing aggregates of sand and stone with petroleum on to the road while the mixture is still hot. The hot-mix asphalt is strong and long-lasting, resistant to freezing and thawing, not affected by deicing agents, flexible, cost-effective, and needs little maintenance.

3 Variables To Consider When Determining Asphalt Paving Costs

Asphalt pavements are made from a mixture of stones, sand, and liquefied asphalt cement at 300°F. Upon cooling, the mixture forms a hard surface that is capable of accommodating heavy weights including vehicles. When computing asphalt paving costs, key among the factors to consider include soil, usage, and size. It is essential that you consult an experienced constructor to give you a quote before commencing on a project to ensure that your budget is capable of executing the task to completion.

Soil

The type of soil in the area to be paved plays a vital role in influencing asphalt paving costs. The kind of soil has a direct impact on the type of subgrade that will be used to support the load which will be transmitted from the pavement. The cost of paving increases with the increase in subgrade thickness. The subgrade is the working platform upon which the construction equipment is supported and is also the foundation to the pavement structure for supporting and distributing the traffic load. It is, therefore, critical to evaluate the how strong the subgrade should be before embarking on a pavement’s structural design. Failure to provide the required subgrade thickness can result in deflection rendering your work to be useless. Different soil types have to vary (texture) support capabilities which influence the depth of the subgrade. Soil texture is the average size of its mineral particles, and it defines how a type of soil can be used. Usually, most natural soils are made of different particle sizes which are used to distinguish one type from the other. Soils can be categorized into three main classes based on texture: Light, medium, and heavy-textured or fine grained. The three categories can further be classified as gravels, silts, sands, or clays.

Usage

The core function of an asphalt pavement is to distribute the weight on the wheels to the supporting subgrade. Asphalt paving costs vary with the type of load that will be accommodated on the pavement. Axle load can be classified into single, tandem, and multiple and can weigh up to 50,000 pounds. Asphalt pavements for use by tandem and multiple axle loads experience reduced load effects and thus, have a long lifespan. Asphalt pavements for use by single axle loads lack a diminished load effect and are thus, costly to pave due to the high-quality requirements to lengthen their lifespan. The volume and distribution of a load play a critical role in estimating the anticipated life of asphalt pavement and consequently, its cost. Usage of asphalt pavement can be predicted based on historical traffic records and truck percentage. To determine the effect of traffic, you require to establish the total volume of the two-way Average Daily Traffic (ADT). You can estimate a road’s ADT by use of a traffic map or a pneumatic tube on the road for some days. Traffic weight can have a dramatic effect on asphalt paving costs. Design differences have a direct impact on material, labor and equipment costs.

Size

The size of the area to be paved also impacts on the cost of asphalt paving. Size differences can be in parameters such as the gradient of the area to be paved, the extent of ground clearance required including the removal of physical barriers such as trees and buildings. Also, the cost of paving can be affected by whether the pavement will be flat or will have peaks and depressions to control the movement of storm water.
