Ever since the beginning of civilization, road builders have been working on securing avenues of travel for the inhabitants of the world. Beginning with dirt roads, they went to a mixture of rock and sand, moving to where we have today's multi-functional roadways. Whenever governmental organizations or individuals decide to pave streets in an area, they must first decide on the type of roadway to use.

Difficulty: Challenging
Instructions

Things You'll Need:

  • Construction contractor
  • Road machines
  • Plans for road construction
  1. Step 1

    Develop your sub grade. This decision is a choice between lime stabilized sub grade (lime mixed with soil for a depth of six inches) or flex base (a layer of crushed stone with a lot of stone dust) to act as a binder. When water is added and the sub grade is put in place, it will set up hard. This layer is the first you will pave.

  2. Step 2

    Realize that choosing the type of mix is a cost-valued engineering decision. Those in charge must decide what works best in an area at the best price. For high clay content soil, it is best to use a lime base. High residential traffic areas work well with flex base, but heavy commercial traffic neighborhoods need a more traditional concrete road base.

  3. Step 3

    Choose the right contractor to do the work when you pave. For this step, you will get the plans approved by the county or design engineer before putting the project out to bid. Have the contract signed and choose the staff. You will need an inspection staff and an engineer for plan review. Next, make a calendar-day deadline.

  4. Step 4

    Grade the trail that will eventually become the road by scraping it with a road machine made specifically to grade below the surface of vegetation layers. Smooth preparation and compaction of the bare ground is a vital step for preparing and paving the road.

  5. Step 5

    Roll out your sub grade mix onto the graded area prior to putting in your flex base, so that it will be solid and sturdy. Over a period of time, the sub grade will move and swell; but it is a continuous barrier between the raw soil and the paving materials.

  6. Step 6

    Select your type of mix for the top layer. The choices are seal coat (asphalt covered rock), multi-layered hot mix asphalt concrete (HMAC) and traditional reinforced concrete paving (RCP). Your contractor will oversee the application and rolling of the paving mix and the inspector will approve that the project has been done correctly.

Tips & Warnings
  • The reason for a calendar-day deadline is to hold the contractor accountable if the work (to pave) lasts beyond this date.
  • The information in this article is extremely simplified.
