Understanding the Purpose of Road Construction
It may seem ironic that road construction is supposed to make commuting faster and easier when it actually makes it slower and harder to navigate thorough while construction is actually happening. Even though it is quite possibly the most annoying thing you encounter to and from work each day, road construction actually does serve a purpose.

Understanding the Purpose of Road Construction
Tom Selwick is a public safety representative for 25 years and has authored hundreds of articles relating to public safety and wellness. He recommends (http://www.interwestsafety.com) as a reference to increase public safety.
Sometimes, the “road construction” is not for the roads at all; it is for what is under them. This can be sewer pipes, gas lines, sub-electrical systems, etc. all of which run underneath the streets that cars drive on.
Crews have to sections of the roads and tear up the pavement to gain access to these things and fix, add, or remove whatever they need. In the oil and gas industry, directional drilling involves laterally drilling of various wells through a zone of oil- or gas-bearing rock at angles from a vertical well-hole.
Horizontal directional drilling is also used in the installation of utility pipelines and conduits. A pilot borehole is drilled along a pre-determined bore path from the surface with minimum disturbance.
It is mainly used for making crossings under rivers, roads, and existing structures with the purpose of installing pipes and conduits to transport different types of fluids and materials. Horizontal directional drilling is a way to get utilities from one point to another without destroying the existing ground or obstacles that are in between the two points.
Directional drilling goes above and beyond traditional trenching; it connects utilities and services in places where traditional trenching is not possible. Open cut, or trenching, is the most common way to install and connect utilities, but it has some limitations.
This method can only be used when the ground above the utilities can be disturbed and there are no buildings, roadways or other obstructions in the way. Horizontal directional drilling can be used in the same situation where open cut is planned, but it can also be used to go under roads, sidewalks, rivers, even houses if there is a need for it.
These two technologies usually complement each other in the field. Trenching or plowing is more cost effective but it has limitations; and directional drilling takes care of everything else but at a higher cost.
The horizontal directional drilling machines are heavy, run on tracks, and tend to disturb or damage the area below them or where they transit. Another area that will cause some trouble is the water used for the boring.
The water will usually come up to the surface of the ground; which causes minimal disturbances unless it is an area where sod or grass seed needs to be replaced. For the most part, horizontal directional drilling will only disturb the location the machine is set up at and any place that utilities need to be connected.
In some circumstances, a drill can be set up on the side of the road, and the only disturbance will be from the footprints of the locator. If you are looking for minimal damage to your existing ground, HDD is the method to be used.
Concrete curb construction using slip-forms can provide several benefits and a better finished project. Concrete curbs are placed using a low-slump concrete which can harden in a relatively small amount of time, instead of longer periods when regular concrete is used.
The concrete used for curbs can be placed directly into hoppers of the slip-form equipment, and start placing it immediately. Concrete curbs are very important for preventing a rapid decay of road surface.
Concrete curbs strengthen the pavement surface, confine flexible pavement, and improve sub-base compaction. Concrete curbs also maintain the pavement edge’s integrity and reduces the space needed when ROW are being required.
It eliminates drainage swales and flat side slopes and minimizes drainage maintenance works. It reduces erosion and sediments going into storm sewer systems.
It also creates a visual border of the pavement; which is ideal for drivers at night. They also reduce the length of the driveway from the edge of the street.
Slip-form benefits are various as well. These give straighter edges can be obtained when compared to regular forms.
It reduces steel or wood forms use and consumption, and will allow for a better sloped surface finishing. It also reduces or eliminates the need for intermediate spacers or templates needed to achieve required slope.
Water will also flow better when compared to regular forms concrete curbs. This also reduces the waste of concrete material since it is placed directly into the machine.
