Once it is necessary to carry out intensive repair and replacement of culvert structures. The serious ramifications of such undertakings and the financial constraints faced, make the successful carrying out of the project impractical.
Measures have been devised where it is now possible to carry out the rehabilitation and lining of the culvert structures that will result in more durable and effective functionality. While this is done, the interruption on the traffic flow and the impact on the public is greatly minimized.
Proper evaluation of the structural condition of the culvert that is to undergo rehabilitation and lining is the initial step that should be taken. Additionally, it is crucial that company assigned the project gets an understanding of the features of the structure type and the materials that were employed in its construction.
If the culvert rehabilitation and lining is to be successfully performed it is vital that the firm assigned the work considers the geometric characteristics that are specific to the culvert product and materials that are the subject of the assessment. Every material used in the manufacture and installation of the culvert is different and unique and must follow a particular process of evaluation.
An effective culvert rehabilitation will be done upon accurate assessment of structural adequacy and the ability to determine the lifespan of the culvert. This evaluation process also helps to determine if the culvert should be rehabilitated or replaced.
Effective culvert rehabilitation will only be achievable if the contractor undertaking the project has compliance to the necessary OSHA regulations. This will include inspector safety precautions and guidelines that govern confined space entry.
The company undertaking the culvert rehabilitation project must compare the assessment statistics that is available to them before commencing the work. In this regard the focus should be on the invert clogging, cracking and joint separation among others.
It is recommended to carry out the processes of measuring, recording and comparing the cross-sectional shape dimensions of the culvert structure to the measurements gained from earlier evaluations. The reason this is an integral component of the process is that it helps the engineer determine if there is existence of a definite sequence of deflection and movement.
Not only is the culvert rehabilitation contractor expected to note any changes that are on the surface of the road but must institute an investigation into it. Other structures that should be considered in the investigation will include the shoulders, the adjacent side fills and guardrails.
Noting and inspecting effects of erosion, signs of perforations and loss of abrasion will be required for the firm hired to carry out culvert rehabilitation and lining. In the interest of public safety, it is crucial to make other changes that could adversely affect the structural integrity of the roadway subjects of the inspection.
